Hello all, I am having overheating issues with my parents van, it is a 2005 Chrysler town and country 3.3L. The van started over heating a couple months ago and has not been driven much since. The radiator had a small hole in it so I replaced it. The van will blow water out of the radiator without heating up. I can see the water circulating in the radiator with the cap off. I read that these vans had problems with heads cracking. I pressurixed the radiator to 15lbs and the next morning there was no pressure in the cooling system. I have never deals with a problem like this so I figured you all would be my best bet for help. Thanks in advance.

 

more then likely a leak iv personally never seen cracked heads on the 3.3 or 3.8

 

You may need something like this example:

 

Leak iv?

 

coolant in oil ? or oily coolant ? probably a head gasket if you seeing blowby in radiator... or , of course a head crack... did it overheat badly at one time or another ? usually the reason... good tech should be able to diagnose fairly quickly.. best of luck

 

COOLANT LEAK and iv i have sorry short hand with as much typing and txting i do all day.

 

I have 05 town and country with the 3.3 it runs good it don't overheat but after it runs for little it will push water back out the resivor jug any ideas.

 

A pressurized cooling system is only there forr very hot climates, so that the coolant may get to OVER 100*C without boiling. If you're getting a lot of pressure at modest temperatures, it's likely that combustion gasses are getting into the coolant water, usually due to a defective head gasket, or a warped cylinder head. If you've a good snifter, lifting the filler cap and having a good sniff usually confirms. Keep your face away from the filler cap when loosening. That's all hopeful -- it could be a cracked head -- not good for the wallet.
