So 2 days ago (I think lol) I noticed that my tstat housing has been leaking a tiny bit of coolant, it turned into nasty looking gunk around the edges :p so I decided to change my Tstat gasket and i noticed today that it's still doing it
My question is, can I used some RTV on the housing to seal it up some more?

Notice the yellowish gunk around the housing :p

 

Clean the mating surfaces with a piece of sandpaper on a flatboard, then apply a thin coat of RTV to both sides of the gasket to fill any slight imperfections in the mating surfaces.

 

Did you file away too much making it shiny???

They make black RTV gasket sealer, use it

 

Well the housing doesn't have a gasket, just on around the lip of the thermostat which sits inside the LIM

 

Sorry about that. I was answering an email about a SBC and had it on my mind. After cleaning the mating surfaces with a flatboard apply a thin coat of grease to the o-ring and a thin coat of RTV to the mating surface of the housing.

 

nope I only sanded lightly to clean up the mating surface
I wanted to polish it but I gave up haha I really need a dremel to get all the details
I'm debating wether I should get this right now or a tune up for monte



And btw look what I parked next to yesterday haha yep it's a purple one


I'm think I should get the red one? Lol

 

Lol it's all good and yep I'm buying the red RTV , it's high temp Haha

 

I always use black, I have used stuff that stays flexiable and ended up leaking again

 

I already bought it I guess I could give this a try, it's only $5

 

Did I say black a few posts ago

I hope the red works for you lol.

Isn't that a beautiful purple?!?!
