I have replaced the t-stat about 8 months ago now its leaking again. Has anybody had problems with the housing. I'm going to buy another gasket or stat and thinking of replacing the housing. Is this a common problem.

It's a 2004 ram 1500 with the hemi.

Thanks for the help.

 

Nope, not too common. Put you some RTV on the gasket this time and you should be golden...

 

Thanks for the help. I will try rtv when i replace it.

 

ditto. I always use RTV sealant with paper gaskets. If there is ever an o-ring type gasket for those, a small bead on the outer edge helps as well. It'll help if the contact area the o-rings rests against isn't prefectly smooth/clean because oxidization of the aluminum is inevitable with coolant.

 

my 2004 does the same thing and has from day one. replace termostat and gasket twice.. still does it..its a very small leak though. few drops an hour at most..

 

Don't know if this is a contributing factor or not but....the Tstat housing is supposed to fit one way on the 5.7.
It should have "front" stamped on it Si it faces forward.
Just a thought??

 

Make sure you tighten the houseing evenly, 1/4 turns at a time. If not in can warp the houseing and put uneven persser on the gasget and the leak in a short amout of time.
