The top of the thermostat housing has a weep. I fitted a new gasket when i fitted the new thermostat but hasnt worked.. So will fit a new one with silicone top and bottom... Does anybody know fhe torque specs for the two bolts?


The last time i did it i damagdd the threads on the inlet and had to change it and scared as such of repeating myself again :-/

Run a file over the mating face when you get it off, may be a little distorted?

Or you could get one of thesescratchchin

Presonnally I don't like "silicone" sealants, with both faces flat and a new "Cornflake packet" gasket a smear of Hylomar should be fine, is on mine.

No idea on torque, just nip up "sensible tight" (use a short spanner not a huge great 1/2" drive ratchet if you don't trust yourself).
It's not the tightness but the good contact between the faces that make the seal (if that makes sense!)

That's what i was thinking but wasn't going to say encased it sounded daft.


I have some hermatite and RTV silicone i could use.



The one that came with the new thermostat was a universal one and is alot thinner then a cereal box type.

Tbh Mike, its the best way.


Right the deed is done, the old gasket was just silicone. At some going clearly i and my dad thought it was better then the crap tissue paper that came with the thermostat so, cherrios has better have a whole lot of goodness in then little 'o's bbecause thats what now is my new gasket.


Cleaned the faces up and dried. Rtv on the bottom (couldn't find my hermatite ) then basket then rtv silicone again. Top on, bolts in, hand tight, socket in hand tight then small spanner about half a turn then a quick nip.



I'll give it a few hours to set then fill up and find out :-/

Brilliant!!! What i have done is used a small spanner and so far seems ok.


Did notice a tiny bit of water earlier so double checked and nipped it up a 1/8 of a turn. Seems ok now... However we'll see

Some of those 'replacement' gaskets are utter crap, and as you say, very, very thin. I have a sheet of thicker gasket paper I bought from local car shop, and have made up my own, and yes I have used a cornflake/food cardboard box too.

I reckon as the engines get older, they do develop some slight warps (especially the ally bits), and that's enough to weep - thicker gaskets (and sealer) can compensate....
