If it is leaking anti freeze when it is closed or not letting you bleed anti freeze from system it is bad but most likely you still have air in the system or you may have a bad head gasket.

If you got a 2,4 liter or 2,7 engine it´s most likely your head gasket, (gasket fault usually appears around 80000 miles) check your oil. If you got white/yellow stuff on your oil dipstick that would be a indicator on leaky head gasket. If there is a radiator cap on your model change that ( 15 dollar fix) release spring to the overflow tank might be faulty.. Try that first. step 2 get the head pressure testet and take it from there. If the head gasket is faulty, then you have to change your water pump/ timing belt while your at it. this is a estimated 12-15 hour fix in a car shop. be prepared for a chock when you get the price of the fix. Get a couple of shops to give you an offer. I replaced mine my self, took me 25 hours and about 900-1000 dollars in parts.


would my engine light come on if it is my head gasket?

No, that would not be the case, Are you constantly filling fluids on the radiator system, is your smoke from engine more white than usual? what kind of engine 2,4 l or 2,7 ext does your car have ? If the car is burning water with fuel the sensor on your cad might be giving you the check engine light. Bit more info from you might be useful :)

Have you heard strange noises (squeking) when you start your engine up in the morning ? or when engine is cold.


I have a 2.7 engine and the coolant bubbles when I start the car then the car begins to run hot.

1 out of 1 people think this is helpful.

how many miles on engine?


and no none that other stuff is happening of what you said. but we did bleed the coolant of the bleed valve stem and more coolant came into the radiator. but it still running hot and bubbling.


about 142000-146000 miles. also will BlueDevil Head Gasket Sealer work if it is the gasket?

how many minutes until it start´s to bubble and overheat?


fist it took about 10 minutes know it bubbles like right when i start the engine.

99% sure,head gasket fault or crack in head, sorry to say. Take it to the shop, have it pressure tested (the head). First it sounded like it was your waterpump (would be if the car has gone that millage without replacement), leave that to the 1 % but unlikely. There is no easy fix to this with sealant´s. http://www.ebay.com/itm/01-09-Chrysler-2-7-V6-DOHC-MLS-Head- Gasket-Set-w-Bolts-Kit-167-EER-engine-parts-/160723706395? hash=item256be1221b&vxp=mtr http://www.ebay.com/itm/98-09-Chrysler-Dodge-2-7L-167-V6-Engine- Timing-Chain-Kit-w-o-Gears-Water-Pump-/151749843132? fits=Year%3A2009%7CMake%3AChrysler&hash=item2354fed8bc&vx p=mtr these are the parts you need, then find a handy man :) Hope this is useful , greetings from Reykjavik, Iceland.

These 2, sorry about the other mess


I took it to a shop n they said it was the thermostat thats why I changed it. But i guess its not but anyway thanks for information, i either take it to my regular mechanic or trade it in.

Good luck :)



Chryslers look nice, but the 2,7 L and 2,4 liters are known for these problems. And faulty transmissions (Watch ot for Avenger and Dodge too, they have the same engine and transmission) if you are trading your car in.


okay so can you answer this for me. are the 2010-2015 jeep wrangler unlimited good cars?

2010 and 2013 are the best years, keep away from the 2012 model. Also 2007 and 2008.


okay thanks what about 2014 and 2015?

In general, they are easy to maintain and come with a good drive train and engine. solid car over all.


okay thanks or the information.

the 2014 and 2015 models are solid models and look nice :)
