Thanks man, I just got one of these last week and it's been leaking coolant from the reservoir and almost overheating. Fortunately I haven't been driving far enough to get too hot. I'm going to replace the reservoir, thermostat, and several hoses today and flush it, but I didn't know where the thermostat even was. I haven't picked up a manual for it yet and the thermostat on my old Nissan is at the top of the engine where the upper hose goes into the block. So far I really like the jeep, the only jeep I've had before was like a 96 iirc Grand Cherokee that had all of the electrical problems. This one is much better already. BTW I'm going to do a full maintenance schedule very soon, just had to take care of this first. I'm almost tempted to replace the water pump and serpentine belt today too but I kinda need the truck tomorrow and since I'm unfamiliar with the engine I'm not exactly confident i could manage all that before dark.
Thanks for sharing your knowledge. My jeep was running hot while driving and cooled down at idle. Turns out the thermostat bypass bleed was facing downward. Issue now fixed jeep running good as new. Thank you
I had to diag an overheating jeep this week, that just left another shop. You know how long it took me to realize he put the thermostat in backwards!!! It fit in there, and generally looked right, at a glance. Wasn't till I looked up procedure, did I see a picture of the thermostat installed. And it hit me. So much harder to diag bad work, vs natural failures!
Only thing I would add to this video is a warning about using the pitcock or drain cock on these new plastic radiators, I never use them you don't want to be that guy, that can't get it to stop leaking or break it off completely, then you have to replace the hole radiator for a few hundred dollars. I have been working on cars sence I was 10 years old and even raced NHRA drag cars. I allwyas break the lower rad hose loose to drain, much safer. But other then that you nailed it brother.
Great video, Stant had advised to change both the rad cap and thermostat every 5 years, both have springs that get weak over time and the rad cap also has three rubber gaskets that dry out. Stick with Stant brand or OEM.
I usually wait for the cap to fail. To replace it. Don't do this. The last time. I didn't get all the pieces of the seal, out of the the reservoir. First leak later. The fluid level dropped, and pieces of rubber got sucked into my electric water pump, and killed it. It's a good thing I don't have to pay for labor. But an extra $300 on a dead water pump that was fairly new, isn't nothin.
@@emilyhofland8219 Long before the cap fails you lower the boiling point as the spring weakens and the rubber gasket dries out, cheap maintenance item to replace..
Quick question, might have some input. My 02 Liberty starts getting hot if my heat isn’t cranked. Have got hot air, drives at operating temperature but slowing down for trail crawling or spinning tires in 2wd (mud/snow) it starts to creep
That can kill an otherwise good V-6 quick. I'm currently about to replace the one that failed in mine. The on board computer reader can save you potentially loads more $ and headaches than it costs. This is engine #2 and the second it ran a little rough I plugged in. Faulty thermostat... $5 A faulty thermostat is what killed the first motor.
Hey I recently changed my thermostat because it was leaking from the seal now my car still over heats after 40 mins or so of driving it but I didn't know mess with the brown thing you showed on the video to lift up. Do you think that's whats causing it to over heat ?
Avary Carter several different things can cause overheating. The thermostat position is important in order to allow trapped air to get out of the system. Air in the system can cause overheating. It is also important to check the cap on the expansion tank. If it is not holding correct pressure it can cause overheating. Make sure you radiator fan is working as well.
I have a 2002 Jeep Liberty 3.7 which overheats after changing the thermostat. Checked the orientation of the thermostat while installing to make sure it was in the correct position. Attempting to release the air from the system and bleeder screw is stuck to the point I have distorted the hex socket. I have put acetone and other penetrating liquids to no avail. I need another way to release the air without the bleeder screw. Any thoughts?
dave dutcher make sure the small line that comes back to the coolant reservoir has coolant flowing back to the reservoir. Then drive the vehicle on to a small hill from various angles to help move any air pockets.
Great video. Question I had my water pump, thermostat and housing, both radiator hoses replaced, radiator fan, temperature sensor, and the dam module. But my temp gage on the dash will go up way past mid line. When I’m driving. Not sure what to do
@@YourCarGuyDR well it had stalled out on me on the road twice last week, then it wouldn’t start after coming out of Walmart. I had topped off the reservoir previous weekend. Long story short I thought it was the fuel pump replaced. The fuel pump started driving home went to a store again and it did the same thing it wouldn’t start. I took it to a buddies house and put a bunch of water in it. That’s when I started replacing everything only thing I have left to replace is the radiator. It’s possible that the thermostat bleeder hole could be upside down. I’m gonna check it out when I replace the radiator.
@@EricMdy definitely check the air bleed. If it is wrong it can cause your symptoms. Make sure to check the underside of your oil cap for any chocolate milk type residue. This could indicate coolant in the oil.
Hey! I think I need to start fixing our car myself because the bills are adding up. We have had an issue with our coolant for multiple months now. The mechanic suspected a broken thermostat, but it actually opened when tested. However only half of the radiator was hot when put back in. Now he took it out completely and the coolant level stays kind of the same, the engine doesn't appear to overheat, but it's not optimal, because sometimes I'll drive a bit, have the car parked and the reservoir of the coolant will overfloat although it isn't supposed to be full... Do you now that it could be? I think I'll order a new water pump, thermostat and sensor just in case and try to replace all those things myself.
If you have air trapped in the cooling system you could open that plug and let out the air while the engine is cold and you are filling the system then close it when it is full to that point. Because of the way the system is designed it doesn’t have much issue with trapped air as long as the return line to the reservoir is not clogged.
we have super cold temperatures here in southeast kansas today ....car heater blowing cold& over heating in my 2003 jeep liberty... do you think its the thermostat??....no issues unitl today
Hi I have a question so my car started overheating it’s a jeep just like the one you have but it only overheats when I have the AC on,could it be the thermostat that needs to be replaced or what do you think? Help!
When you a/c is on it adds more load to the engine. I would first verify that the radiator fan is working properly. Then check airflow across the radiator, make sure it isn’t plugged with leaves or debris between the a/c condenser and the radiator. Next I would check for proper pressure in the cooling system. If the cap isn’t holding correct pressure it won’t cool as well. Also check your belt and tensioner.
Jorge Jimenez the bolt only need about 17ft/lb of torque. There may be a crack in the housing if it is coming around the bolts. You could try sealing the bolts with a liquid gasket material.
That can be tough. If the bolts won’t come out you risk breaking them off. Some PB Blaster and heat can help but if the bolt breaks you will likely have a lot more work on your hands.
@@YourCarGuyDR thanks for your response, actually I just changed with new hose as the previous one already expanded from the original shape so just worry it’s going to blown because more I put accelerated more expanding the top hose. Any ideas? Such as blocked radiator or something else but the temperature is ok and the engine never overheat.
Nice video. I have a 2006 Jeep Liberty that provides poor heating for me but was overheating yesterday. Do you think replacing the thermostat can help both problems? Could there be some other common root cause? Appreciate you work for this community.
@@YourCarGuyDR thank you for your suggestion, it was the sensor and it is doing better. I have another problem, sometimes it does not start but it startles but not start. I disconnect the battery for 30 minutes and it cranks up. Any ideas?
@@carlosgomez9220 that one may be a bit more difficult to diagnose without seeing it. I would clean the battery connections really well and make sure they are tight. You may have something drawing down the battery when it is hooked up.
Did you orient the thermostat with the air bleed up? Have you verified that you got the cooling system bled of all air? What prompted you to change the thermostat?
Stephen Smith check your cap on the expansion tank. If it is not sealing well and holding the proper pressure the cooling efficiency of the system goes down. Under pressure the coolant has better heat transfer, while climbing the engine is under higher load and will generate more heat. If the cap isn’t holding proper pressure it can allow overheating under load.
My 2005 3.5L Jeep Liberty 6 clyinder cooling fan doesn’t work. Hasn’t overheated yet but do you know what the causes of a failed cooling fan is? I also suspect that my radiator hose is soft like easy to squeeze
The fans will fail over time and the brushes for the electric motor wear out. Remember the fan only comes on when it needs to due to coolant temp or a/c pressure. It’s probably time for new hoses.
My 2004 Jeep Liberty over heats and is not blowing hot air, do you think is a good idea to start by replacing the thermostat or do you think this may be a water pump issue? Thanks!
Jose Trejo if your overheating but not getting hot air most likely your system is low on coolant or has an air pocket in the cooling system. It is also possible that the water pump isn’t flowing at all but that is rare.
If anyone is still having an issue with this please take a look at The Clay Way video. He explains about there being a certain way of placing the thermostat in the housing.I hope it helps. I’m currently still trying to get a mechanic that will listen to me & do it this way since I keep having issues with it but they just won’t. I don’t know if it’s because I’m a girl or it’s just an ego thing. Anyway, I hope it helps & if it does let me know please so I can show it to a mechanic as proof. Thank you in advance.😊 czcams.com/video/THySqnGmrWk/video.html
wrwatson39 a couple of things to check. 1 was it overheating before you changed the thermostat? If so you likely have a plugged radiator. If not did you make sure to orient the the thermostat correctly?
wrwatson39 I doubt your heater core is bad unless it is leaking. Otherwise it sounds like you have a large air pocket in the heater core which will cause it not to heat. Make sure your reservoir is full and when running you should see coolant coming back to the tank from the small return line. Run it with the heater on full heat and the cap off the coolant tank. Keep adding coolant as needed.
Thank you so much, I just replaced my fan, and I have never worked on a car in my life. Husband didn’t want to help and I found you!! 🥰😘
Hopefully you have rightly embarrassed your husband with your mechanic skills.
