- WHY COOLANT COMES OUT OF RADIATOR CAP OR OVERFLOW TANK RESERVOIR ON A CAR
If you have a car that has coolant antifreeze coming out of the overflow bottle or coolant coming from the radiator cap in this video we will explain what often can cause coolant to come out of the radiator cap or coolant to come out of the overflow reservoir tank. Often coolant coming out of the radiator cap or overflow tank is a sign of engine overheating or blown head gasket but in other cases it could be bad radiator cap or bad coolant overflow reservoir cap or even maybe the cooling system not being bleed correctly. Hopefully the video will be helpful to any of you that need to fix coolant coming out of the overflow reservoir tank or the radiator cap.

How are you doing? I looked for you on CZcams just wanted to say thank you so much. My Jeep cherokee 2001kj 3.7litres was having cooling system failure and I flashed the cooling system a number of times but the problem continued. Tuesday nigh after watching your video then my attention moved to the radiator cup which I knew was in bad shape but I didn't know the importance of it being in good shape. Today I bought a new radiator cup and went for a test drive and the results were amazing, no boiling of coolant, engine no longer getting hotter than the normal temperature and no coolant coming out of the reservoir whenever I just stop or pack. Thanks to you my baby is back on the road. Continue with the same spirit. The radiator cup is almost $3 dollars here in Zambia just $3 dollars would have killed my baby and I would've spent more on the gasket
Great job. My Guy... You explained that perfectly,but there is 1 other way .
Great info 👍🏻👍🏻 need help on R36
That was awesome 👏🏿
Hello, i have a problem with my bmw e60, the climate controll only blows air through the vents in the middle of the car, on the middle of the dashboard, and in the back of center consoll towards the backseats) not on the sides on the dash or in front of the dash. Do you know what can be the problem?
Awesome video....great explanation
I had a cracked head, but didn't notice it, when I had the upper intake gasket go out on my 2002 Grand AM GT 3.4l V6. So I took everything apart and check that all clearances we still within standards. I missed a small crack between the valves. So when driving the car, everything seemed fine until I would step on the gas hard. Then I would noticed bubbling in the cooling system. It would leak off a little throught the overflow tube. But granny driving was fine around town. When I decided to pull each spark plug, one was stuck. It stripped the thread when took it out. So when I pulled that head, I was able to see it, now that it was bad. So I changed the head, put it all together, then it was noisy, knocking sound, until it warms up. Wasn't exactly sure what was causing the knock now. Thought something happened to cause rod bearings to wear out, so when I was replacing those, I noticed when that cylinder was at top dead center, it would clunk to the side. It seems the time driving it and it kept trying to over heat only when stepping on it at full throttle, must have caused the one to wear out more, when it would keep getting heated up. So I now have piston slap on that cylinder. The original upper intake gasket on that GM 3.4l V6 is a terrible design. The replacement one has metal spacers, to prevent the gasket from being crushed too much, during installation. The one that failed was just plastic with the silicone seal bead. I just wish I noticed the crack in the head when I had it all apart. Lesson learned.
Is it the same with the 4.3 liter?
@anthonymurlowski8521 IDK
Sorry I took so long to respond. My wife has been sick, and I have been forgetting to check my email.
Thank you I put too much in my white reservoir plastic. Is it safe to drive it for 20 minutes or so?
Awesome
Do one on the northstar 4.6?
i recently got a 2014 veloster turbo. replaced thermostat,waterpump and cap. noticed every few days it would start to run hot and i would need to add coolant. just noticed after every drive the coolant is seeping out the reservoir tank drain hose and the reservoir is full. will check the sensor next. if it continues how can i test if is the head gasket or head? thank you for the great video...
Leakdown test.
I have a problem
When i turn on the engine the water get out of expansion tank
I checked the cooling systems but to no avail😢
Hi and great videos. Question is… just bought a 2.5 Sentra that blows air and coolant through the filler cap and acts like a blown head gasket. There is no coolant in the oil, no residue on oil cap and the car does not smoke. It does still get hot. I bypassed the heater core since I’m in Florida. Both thermostats were changed also. The radiator seems new but looking forwards to seeing if something is clogged. Any suggestions my only bet is radiator clogged or water pump bad. Everything looks new but coolant did seem brownish. Never had these symptoms before and only thing I can think of would be worst case scenario the head gasket regardless it was changed. Only 100k on the engine. Any idea would be appreciated
Have you fixed this?
The coolant on my 1964 ford econoline overflows via the tube attached to the radiator cap after or once I turn the engine off. While running it doesn't leak and the engine does not overheat.
It is not leaking from radiator, hoses, or any other place. I don't believe it could be head gasket because the engine has been rebuilt. I did recently change out the radiator cap, need to know if that's what is causing to overflow? Appreciate any response and/or information you provide.
You sort it after ? I have overflow issues yet garage done all testing hg was done months ago very odd ..it did recently overheat again or at least coolant temp was high
Have you solved that issue with your car mine is doing the same
What fixed it ?
Blockage in old vehicles can be a major cause . Big headache.
I replaced my radiator with a new one..temp sensor replaced..replaced my thermostat multiple times..new water pump and new reservoir cap and it still gets hot quick
So it can range from a bad seal on the resevoir cap, all the way to replacing the entire engine head. Got it. You explained there is about 10 different reasons that it can happen lol you mightve well just said "if u have a coolant leak, well it could really be anything"
Yup, which is why you pressure test and/or block test
@@babypinkbean turned out it was just my thermostat. Replaced it and no problems since
You car was thrwing the coolant to the reservoir?
@@westcoast2372 yeah thanx tips🤦♂️ welcome to mechanics. Its process of elimination. If you wanted a direct answer then take it to a mechanic instead of seeming irritated for the options it could be
I opened my rad cap and was hoping to bleed the system but coolant started coming out. Do you think blown head gasket.
Same 😢😢 this happened after coolant flush
I've got the weirdest car, not long after buying it I noticed the Coolant expansion chamber was way below minimum so topped it up assuming the previous owner just hadnt done it in a while, checked it again two weeks ater and same thing so topped it up again, after that I checked almost every day. Never had any leaks, no warning lights, no overheating or anything, no signs other than the visual check with missing coolant. Then not long after the 2nd top up it started to show some leaks/drips under the car, nothing major just very light loss. Kept topping up and keeping eye on it until eventually taking it to garage who diagnosed a crack in thermostat housing, they said it was common on the age and model of vehicle I have (2012 citroen DS3) they also said some work had been down around this area as parts were new and mustve had work done recently. Again a month or so later from fixing small leaks like before but not very much, very very light patch.on driveway every so often, usually after a longish drive leaving car overnight id notice a small patch, nothing like before and nowhere near the coolant loss as before. Because of these issues I've been obsessively checking the coolant level and today noticed it had risen to over the max line? Despite as I say the odd drip i expected it to go down slightly, I released the cap slowly expecting a slight rise as sometimes happens when releasing the pressure out the chamber but the level just kept rising to the point where its running out the top onto the floor. I've topped it up twice with approx 500ml of coolant since having it fixed around 6 weeks ago but haven't needed to the past couple weeks as its been consistently on the max.
It's making me think are the levels even consistent when I'm checking it, is it not regulating properly and perhaps when I've thought it needed coolant maybe it didn't? I've not seen it like that ever rising up and out the top. Needless to say I've soaked the excess out with a cloth for now. What could this be?
Potentially an air pocket traped in the system could cause irregular coolant levels, but to be safe, do a hydrocarbon test to see if you're getting exhaust gasses in your cooling system. The tester is relatively inexpensive. If you are, it could be a sign of a blown head gasket.
@midwestfatass coolant has been drained and replaced several times recently could there still be an air pocket there, new water pump was recommended and replaced along with a new thermostat housing where they said it original leaked via a crack, but this problem is still there slightly, I'm sure these mechanics just change things for the sake of it
@campcop9214 if the shop isn't versed on bleeding procedures, the problem could remain. I would, however, do a head gasket leak test as soon as possible. The kit to test it is around 30 bucks, and it's very diy. Super simple. Then at least you can be confident in the health of your engine. Look up testing head gasket on youtube.
@@midwestfatass I've heard of this, I'll try it, I've literally seen nobody say pressure build up could be a failing water pump, 2 recovery breakdowns "specialists" said it looked like a water pump issue so idk feeling quite ripped off by not just who I got the car from but the 4 different people who looked at this car to discover the issue. I don't know what to think.
Thanks for you replies aswell buddy I do appreciate it
I changed out my water pump and thermostat plus new top and bottom hoses new radiator.. and new radiator cap .. and it's still leaking coolant from my overflow bottle .. I have a 2000 Toyota camry 4 cylinder .. please help .. I don't know what else to do
Same issue. Once I figure it out I will come back to this comment and hope it helps you. Unless you’ve already figured it out ?
Is it running hot?
So, my truck does not overheat but the reservoir tank builds a lot of pressure. Also if I keep cap off and turn on truck and mash the gas it will raise up and start overflowing. Don't really notice any loss of coolant at all. Don't have any rough idle or overheating. No kind of misfire. Heat works no heater core problems. Just changed my thermostat. So, just wondering ehat the issue could be.
My EXACT Problem..Did You Find An Answer?
Mine is the same, except it does overheat a bit, I'm wondering what's the problem.
I'm in the same boat here
@@LeetosBeetos No, not yet haven't had the time or money. I have started having a little misfire though. Slight rough idle. And coolant loss but no smoke.
I have changed a few things but started having some coolant loss slight rough idle and misfire but no smoke. So, not sure what's going on with mine at the moment. Have started having a little hesitation issues where it seemed like it wanted to stall but once going it's fine only does it when first start it up.
What if the fan isn’t turning on?
May be due to a bad thermostat or bad radiator fan valve or relay.
Hi
My car getting heat i change radiator cap pump also fine thermostat also But my all coolant coming in external box not going back in radiator i can see some air buble in external tank when water getting full hot
You have air in your cooling system. Watch some videos on how to correctly burp the cooling system
Is it normal if i take the radiator cap out. And turn the truck on for the coolant to overflow and drop outside?
Same thing is happening to mine, I was trying to see if the coolant would bubble when I turned on my car but instead the coolant would just go up and overflow.
@@209MainstDB Someone here in youtube comment me saying that was normal since the cap is off and the truck is on. What i did yesterday i went to buy a new cap. Later during the day im going to check if there wasent any coolant dripping while i drove it yesterday. What i did notist when i got home my truck engine was very hot. Good luck in your vehicle. I'm trying to find why is caussing this issue on my own because here where i live not all mecanics are honest. They like to ripp off clients specially women. They gave a estimate of $350 i advice to let me know first what was the issue i took a video of the problem where it was leaking. I told them to change the spar plugs and transmission oil and motor and the issue of the dripping coolant. Took my truck in at 2pm
They said it was ready next day at 11am. He had a sheet saying i have to pay over $500 i told him you never call me to tell me the issue. And you gave me an estimate of $350 so thats what i only paid. Later when i drove my truck i notist it was getting hot when i turn my cooler system off. Went to see if it had a leak and yes it did. But this time it wasent coolant was just clear water. They tried to make me think i had a problem with my coolant system. Which i didn't believe. I checked my antifreeze bottle which i had added orange antifreeze and was pure water also my radiator had pure clear water in it?? I told this person where they fix it he told me if i tasted it and that i should of taste it i told you come and taste it for me 😂 later next day i call another mecanic and told him why my coolant was overflowing when i took the cap out and turn my truck on he said it was the head gaskets and that it will cost $600 i said why so much he said because we need to take half of your motor out. I said no thank you. Than i said im going to coment here in youtube to experts so they said it was completely normal for it to happen. And to try to buy a new cap too see if when i drive it with the cap on to see if it was because it needed a new cap replacement.
@@AgustinaQuinteroFelix sheesh! Thanks for replying. Yeah hopefully it is normal. Cuz it's gonna be a hassle for a broke person like me lol. But good luck with your truck and your situation, hopefully it gets better and you get everything fixed.
@@209MainstDB Thank you so much. Good luck too you as well. Im broke also. 😔
@@AgustinaQuinteroFelix Put a new cap on did it again
My coolant ends up all in the expansion tank, I’ve tried everything and I’m down to two things, bad water pump or head gasket. 2010 Infiniti fx35 taking it to the shop this week. Not planning on getting a new car so I may end up with a hefty bill.
You get it s9rted after ? I had hg done but still had coolant getting into ex. Tank and over engine . It dies go back in once cooled very odd
@@kevinhancock4064 My HG, water pump timing chain and all other gaskets have been changed.... car isrunning like new, the only thing i've noticed now is that when i picked up the car 200 miles ago, the coolant in the ex tank was at max, now its in between min and max. i was told that there may be air in the system to just top off the expansion tank... idont have any signs of coolant leak anywhere. If you got your HG replace,make sure you get a new Radiator cap. that may the culprit. Make sure its an infiniti one as well. they're pretty inexpensive part.
@David Tufino Photography when you say infinit you mean oe/genuine yes ? Sounds similar to all that I've had done .I was gonna get car today but get it Monday. Its had a new cap which initially they thought it was the issue . The bleeding pressure on my cat however is rev with cap on and up to temp to 2500 revs for 5 minutes then 3000 revs for 5 seconds and of it needs topping up repeat procedure once topped up. . I had a dash coolant temp high warning recently..I know air pockets can also cause this . The garage said they've done all checks etc inc hg checks . Obvs that's their word. They do have a good rep . It's odd. I'll ask them if cap is genuine etc . I just wanted to get some good use from car as I'm not in a position to buy another . Its had new timing chain skim & pressure test intake clean lifters rickers turbo so if I can sort the issue I'd have a good functioning vehicle . That wouod likeky last some time
@David Tufino Photography one thing I do have here only to rule out the smallest of leaks if any . Is dye I used ot on my last vehicle for confirm (found already ) my therm. Housing gasket leak . Cost me 7 quid and coolant to fix .
Mine just leaks on the ground.... a mechanic really messed my car up
You forgot to mention water pump. If water pump fails car will overheat and cause over flow
You think shooting water out the cap is a water pump?
I can't really understand what your saying
