I just got a really clean 2002 civic as my first vehicle and its been burning coolant for about a two months now with no visible leak. me and my friend who is a mechanic have a few ideas on what it could be but "he's been a mechanic for 5 years and I wont lie I don't know jack shit about vehicles but I like learning and i mean I just got my first vehicle 5 months ago lmao" anyway I have like 2 hours until school so I figured I might as well watch some videos to get some ideas, thanks for the video ! simple and easy to understand.
Did you ever figure it out? I got a 2002 crv with the k24 engine and got it at 243k miles. I drive it like a project car, shakey but still takes it. Only thing is.. I burn through oil and coolant before I'm due for an oil change or right on that mile mark. No leaks. Shit weird... but also old and had things like engine mounts come off while delivering pizzas lol. It's crazy what these older honda's can take for a beating. Like old trucks. I'm at 254k miles. Got the AWD too... Just likes to drive hard I think (or say to feel like I'm not killing it). One I get a cherry picker going to take a look cus if the engine is still strong.. .maybe make a sleeper and boost it?
In my case, I'm literally consuming water with " no visible trace". I eather have a physical phenomena going on, or I can consume 1-1/2 gallons of water an hour, with no leaking on the ground or steam out the tail pipe. The water that is getting into the combustion chamber is being turned into energy in order to stay in complience with the conservation of mass.
@@CKG1973 Yes I did! I towed it (cold) a block away from the title pawn place. Then drove it there, pawned the title, walked to the wreaker, drove to the bank and cashed the check! I literally theft the keys in it, in their parking lot. LOL
Thanks for the video! My 2005 civic has been over heating especially more now in the summer. It's never smoked as I pull over quickly. I brought it to two mechanics. (First mechanic) The pressure test went well apparently and no signs of leaking. (Second mechanic) ran dye through and speculates a head gasket issue but is uncertain. When I add coolant, it's 95% into the radiator and not the resevoir. It's hard to want to pay for a head gasket without knowing for sure if that's the issue. If you stumble upon a situation like mine, maybe you could post another video 😊
Alicia Greeley head gasket should have shown up with a pressure drop during the pressure test. Many times the water pump will be your leak but because it is difficult to see can be overlooked. Fill your coolant and then let the car run. While it is running look for drips underneath. Make sure your a/c is off when you do this. If you see a leak to the inside of your passenger tire replace your water pump.
@@YourCarGuyDR thank you! I've seen that issue with a few other videos I've watched. I can definitely see how it can be overlooked! I will give it a try for my next measure. Thank you!
Hey Alicia, did you ever figure it out I am dealing with this now as well. Pressure test came back good, both the engine and rad pressured up and worked good. I do not want to have to pay for a head gasket either.
I have heard that some 8th gen Honda civics have had the engine block crack due to a problem during the casting of the block which will cause a loss of coolant
I had the same issue but I was losing coolant through the expansion tank whenever I was going highway speeds changed multiple things before finally figuring out that the system was over pressurized due to bad head gasket
Hey my 2010 Honda Civic LX is whistling i thought it was alternator bearings but is it the head gasket or what ?? Im getting chest pain driving it which i usually get im sensitive to chemicals
My problem is identical to this. I already had checked the cooling system with no visible leaks on radiator or hoses. I did notice my radiator cap was looking rather.. crusty to say the least. After 3 test drives i had coolant at the bottom of engine bay. Lets see if new cap fixes the issue
@@idkanythingiamme9365 It seems that changing the coolant cap helped a little bit. Not losing coolant as rapidly as before. But there seems to be a wet coolant spot constantly under my radiator. So its like partly fixed. (need to do pressure test)
Gamer Cat some steam will be normal with the cap off. You can get a combustion gas tester which is relatively inexpensive and see if you are getting combustion gas in the coolant. This is an inexpensive way to determine if you have a head gasket issue.
Hopefully this is my problem. I have a 2003 civic and every time I remove the radiator cap to check the coolant level it’s always a little low and yes the coolant overflow bottle is full. I haven’t had time or money to go get a pressure test done. Hopefully it’s not my head gasket. It’s not over heating.
I have the exact same issue on a 99 Civic. It's a slow leak or coolant disappearing somewhere. If I fill my radiator it will take 2-3 months before it will start overheating again. Everything I have replaced coolant related is Honda OEM except the radiator. The radiator is from O'reilly's. It's been driving me nuts because I don't see any visible leaks.
Ginger You will know it’s the coolant if it has a metal cap, follow the hose beside the metal radiator and it will lead you to the coolant reservoir. Under any circumstances do not take metal cap off after the vehicle has been recently running. Please allow 2-3 hour cooling time for your engine before even touching the metal cap if you do not have a coolant reservoir. If you take that metal cap off while the vehicle is hot you are risking serve 3rd degree burns sprinkled all over your body. Please take what I say serious I do not joke around.
I got a 2004 Honda Civic with a mystery water leak. It was venting through a bad radiator cap that problem has been fixed. The system seems to not hold pressure but here's the mystery. How to lose about a quart of water per 10 miles. Recovery tank does not overflow water and recovery tank cold and up to the top no over flow. A blown head gasket would make the radiator puke and it is not puking. Also I got no oil in my water and no water in my oil. No water or steam out exhaust. The engine is not overheating the engine gauge stays right where it is supposed to be until it runs out water. I can't find no pin holes in a radiator hoses or anything. When you turn the engine off you cannot hear no hissing or see any steam. The water just disappears into the Twilight Zone.
Check your water pump. They leak near the passenger tire but often will only leak when running and the coolant/water travels along the chassis and can be difficult to find.
Hi, I just recently bought a used 2008 Honda Civic Si coupe and I noticed there was no coolant in the reservoir. After letting the engine cool down, I fill the reservoir till it hit max. A day later, I took it for a drive and the temperature seemed fine, it was in the middle as it always is, however when I checked the reservoir again and the coolant was all gone! No visible leaks whatsoever. I thought it might be the head gasket, so I turned on the car, warmed it up, and revved the engine. I had a friend check if there was any fluid or white smoke come out of the exhaust and there was none. I checked the radiator cap and it didn’t seem worn out...any theories as to what it could be?
Nick Algiers first check your oil level to make sure it isn’t over full. If the oil looks good the best thing to do is make sure the coolant is full and just let it idle while watching underneath for any drips at all. I would suspect a water pump. They tend to only leak when driving and you may never see any drips.
Might be the heater core too because i think mine is leaking I can definitely smell coolant without the bypass i had on the heater core but now its cold ill have to replace it.
Hi, i have issues with my prestone with my Honda civic 2002. There's air build up in the engine and the prestone goes right into the reservoir, and spilled through the reservoir, and stay full. I have changed the radiator cap and thermostat. No white smoke coming off the muffler, no white desposits in the oil. When i remove the radiator cap after engine cooled up, there's a big bubble of prestone coming off the radiator. I noticed I only started to have issues after I did an oil change. I did not go behond the max. mark. Could be the head gasket, but any other areas that it could be? Mario, Nova Scotia, Canada
Mario Cyr I would go to the auto parts store and get a combustion gas test kit. They are not expensive. It will tell you if you have a blown head gasket or cracked head. It is the most likely issue.
yesterday my civic engine started smoking and engine warms up...i opened the bonet and seen coolant is leaking and there is no coolant and car didnt runs perfectly its all jerking while i rev the engine.. engine sounds like crap and smoke coming from exhaust tooo....help me what would have happened...😣😣
JMP News that doesn’t sound good. You want to refill the coolant (you can use water as a temporary coolant). Then look to see if you have a visible leak. Based on what you have said you may have a blown head gasket which would mean a significant amount of work to repair. Hopefully you just have an external leak. Make sure to check your oil level.

I have an O2 Honda Civic. I replace the radiator and the reservoir because it was having his shoes overheating. My fans work but it was burning through coolant really quickly. Since I have changed out the radiator and everything it's still burns through coolant kind of quick, not as fast as it was. It doesn't overheat anywhere near as much, but now the reservoir has a black buildup in it. Any clue what that could be?
It sounds like you may have a blown head gasket. There is an easy test for this. I will include a link to my video showing this. Easy Test for Blown Head Gasket
There are a couple of tests that can BWE done. One would be a compression test. Low compression on one or more cylinders could indicate a blown head gasket.

If you have combustion gas in your coolant then you likely have a blown head gasket or cracked head.
@@YourCarGuyDR Hi, I did a compression test and the results were good but my coolant overflow tank is empty and smells weird, like gasoline or something.

@@makimano1990 you can fill your coolant and pressure test the cooling system. Look for an external leak. Also get a combustion gas test kit and check for combustion gasses in the cooling system.
I’m having an issue where it seems like fluid is spraying out of the radiator and building up around the battery, causing a lot of steam to billow up. It started yesterday because my serpentine belt broke. I replaced the belt and it’s been running well, but by the end of my commute to work, the battery was steaming again and I opened the hood to see where things had sprayed. Any suggestions for how to remedy this? Should I replace the radiator cap? I don’t really know much about cars, but I rely on my vehicle for literally everything, and I will be completely fucked if it stops working… Don’t really have money to take it to a shop or spend a lot on parts.
@@YourCarGuyDR No actually it got so hot it reached the maximum on the gauge and I had to rush it to the nearest certified Honda mechanic. Time will tell…
I have a 03 civic. It starts overheating periodically, like it goes a week or 2 without overheating then all of a sudden it starts. I have changed the thermostat about 3 months ago. I don't see anywhere that it is leaking... But a few minutes ago I was looking at it and there was a small puddle of coolent on the radiator, not from pouring coolant in. There isn't steam coming from around the radiator cap but rather closer to the puddle. Could this be because I have a cracked radiator?? Please help!
@@YourCarGuyDR or could it be possible for something to be on the verge of going bad inside the radiator? Thank you so much for taking the time to try to help me btw.
Jenny Spencer a lot of times they will leak when cold but seal up when hot due to the expansion of the materials. This particularly happens when the seal between the tank and core is starting to fail. When your car overheats is it low on coolant?
If I am missing half a glass of water in the radiator, I do not fill water and then they disappear that way this is the situation regularly. Is it okay? And in a condensing tank everything is fine
If the radiator continues to lose coolant then you likely have a small leak. I would keep an eye on it and check it regularly. Particularly if you see the temperature run higher than normal.
@@YourCarGuyDRi replaced the radiator a week ago and since that is the situation the amount of water does not continue to drop, I went back to the garage for a test, he checked air pressure and checked that there is no leakage and said that everything is fine, but still continue to monitor that it does not continue to drop. He said that if it keeps going down then there is a problem and if it does not keep going down then everything is fine. The question is is this small lack of water normal? (Half a glass of water) Regarding engine heat there is no change everything is fine
@@os4635 your mechanic has given good advice. The small amount of water is likely due to some air pockets that were in the system from changing the radiator. If it stops losing the small amount there is nothing to worry about.
A proper system should not have any loss. If you have recently had work to the system you may be adding some regularly as all of the air pockets work their way out.
You could have a blown head gasket. These engines also have a metal pipe that runs from the front cover behind the water pump that can crack. It is very difficult to see a leak in that area.
Romantico Poeta the air conditioning shouldn’t have any effect. With the car running look for any drips underneath. Particularly near the passenger side front.
John sarab it was overheating due to low coolant. The first sign the owner noticed was the overheating as most people do not often check their coolant.
Hi im from South Africa I search whole day for a answer. I realy realy realy hope someone can help me. I got a Fiat 128 rally 1974 The radiator cap vacuum part is gone and have no rubber seal on bottom only big top rubber seal. So the water is going freely to the coolant bottel. The cap is open inside. So the water have no pressure and can go freely back and forward without any valve have to open. Now.. can this be the reason my kar overhead after so 10 km or in traffic light it get FAST overheat?
It is possible that this is causing your overheating. The cooling system is significantly less effective when it is not pressurized. If the radiator cap is not holding pressure you will have overheating issues. However there are many other things that can cause overheating issues. But the radiator cap is inexpensive and must be checked.

@@YourCarGuyDR it had no antifreeze 💀
My car coolant gets empty quick especially when i turn on the A/c what's ur recommendation?
Romantico Poeta the air conditioning shouldn’t have any effect. With the car running look for any drips underneath. Particularly near the passenger side front.
Romantico poeta did you fix it i have the same problem
"It gets empty sometimes i dont know why maybe its when u leave ur car parked with the a/c on
Still, why was it losing coolant?
Overheating and losing coolant are two seperate things!
John sarab it was overheating due to low coolant. The first sign the owner noticed was the overheating as most people do not often check their coolant.
So it’s a head gasket it’s going out the tailpipe
Hi im from South Africa
I search whole day for a answer. I realy realy realy hope someone can help me.
I got a Fiat 128 rally 1974
The radiator cap vacuum part is gone and have no rubber seal on bottom only big top rubber seal. So the water is going freely to the coolant bottel. The cap is open inside. So the water have no pressure and can go freely back and forward without any valve have to open.
Now.. can this be the reason my kar overhead after so 10 km or in traffic light it get FAST overheat?
It is possible that this is causing your overheating. The cooling system is significantly less effective when it is not pressurized. If the radiator cap is not holding pressure you will have overheating issues. However there are many other things that can cause overheating issues. But the radiator cap is inexpensive and must be checked.
why don't you show how to replace the part you're suggesting?
There is a separate video on the channel showing how to replace.
your moving the camera too much annoying to watch
You should look in the mirror lol
