Chrysler 300: Why is my 2006 300 2.7L overheating? Ive replaced

This answer was rated:

Why is my 2006 300 2.7L overheating? I've replaced the thermostat twice now, replaced the water pump, replaced the cooling sensor, both fans are working.

I am at a complete loss.

Please advise.

hi


 

tim's auto repair :

sense you have worked on the cooling system


 

tim's auto repair :

lets try something here


 

tim's auto repair :

i think you may have air in the system


 

tim's auto repair :

lets bleed it this way


 

tim's auto repair :

1,you need to remove the radiator/reservoir cap when engine is cold


2-start the engine and let it idle


3-turn the heater on high


4-keep coolant on hand and add it as needed...some coolant may gush out with the air,so be careful


5-keep doing this until the engine is at operating tempeture,the heater is hot and the coolant in the radiator settles down


6-then install the cap


 

tim's auto repair :

if it is still getting hot after you dio this,,


 

tim's auto repair :

you may have a blown head gasket


 

tim's auto repair :

 

Customer:

Thanks for the response. If it was in fact a blown head gasket, how would I test for it?


 


Also, wouldn't I be able to smell something in the exhaust? I'm not sure that I smell anything in the exhaust..?


 


Assuming that I do not smell anything from the exhaust, what else could it be?

tim's auto repair :

hi


 

tim's auto repair :

you wouldnt need to smell anything


 

tim's auto repair :

the head may be equalizing the cooling system


 

tim's auto repair :

causing the coolanyt not to move


 

tim's auto repair :

coolant


 

tim's auto repair :

this would cause it to get hot


 

tim's auto repair :

try bleeding it first
