Hi

My car is a dodge charger 2010 se v6 3.5L


I down the both heads out ,send it to Machine and replaced the full gasket (up &down) I changed the timing belt, pulley, water pump , coolant with 2 pipe ,thermostat and spark plugs.

The car seem ok now except the overheating.





But I believe that, the thermostat should be there for a purpose.

Do you think, I need to down the head again and replace the gasket

 

maybe you got a bad thermostat out of the box. Or did you installed the thermostat inside out?

I don't think it is a waterpump failure or a bad head gasket, because you said it doesn't over heat when you run without a thermostat.

Also, what happen if you blast you heat at full speed?

Or yeah, does the cooling fan work?

 

thank you for replay

the car with the dodge dealer right now, they put another new thermostat again but its same !

the cooling fan working fine

 

If that's the case, I got a feeling the Head Gasket wasn't seated right, or the deck of the block wasn't clean.
Or possibly the machine shop mess up the head. (Had that happened, found out the hard way)

 

yes, I am think to replace the head gasket and do the machine job for the head again

thank you very much for the help

 

Sometimes I like to use those Spray on Gasket sealant. It helps a lot on sealing.

Just make sure the CAN says OK for Head Gasket, waterpump gaskets, etc...
I use that on almost everything except exhaust gaskets. It works great. Just make sure sealing surface is clean, and after you spray the gasket, do NOT drop it on the floor, it will collect dirts.

Or just go to the dealer and buy the Mopar Spray on gasket maker, their
parts guy will know what you are talking about. Tho I think they are made by permatex.




Make sure the Machine shop check for CRACKS on the head.

 

thank you very much for the advice .. I will start the work next week

hope this is final

I will updat the thread, after that

thank you again

 

Hi were you ever able to fix it I’m having the same problem except I bought the car and it has no thermostat and runs fine but wanted to get rid of the check engine and put a new one in and overheats. Bled the system twice too.

 

He hasn't been here in 11 years. I doubt he even still owns the car.
