I've just found my thermostat on the shelf after replacing the coolant switch and pipes and filling the system with fresh anti freeze and water... ;D I don't have a spare stat housing gasket at the mo - has anyone used just liquid gasket on a stat housing? If so whats generally the best method? Apply to both faces, leave two minutes then press together? And how long do you need to leave it till you can run the car? Ill probably get myself a new gasket but not replace it just yet - I can do without the stat for testing etc... A bit annoying Ive wasted so much anti freeze though when the budget is at an all time low!!

TBH, I'd get (or make) a replacement gasket - instant gasket can fail, leaving you needing even more antifreeze.
You could always catch and re-use the antifreeze that's in there - just make sure it doesn't get dirty.

Blue hylomar like you said, or glue it together with the orange silicone RTV stuff. I've never been a fan of Hermetite Red though.

Ay fair play I'll hunt down a gask wet.... I'll attempt to catch the anti freeze out the lower rad hose and inspect it... Feel like a right skav but needs must at the minute.....

Normal orange instant gasket is fine, i use it all the time on pintos cos the stat housings rot and are rarely flat on the gasket face, just pop off the bottom hose and catch the coolant i do that on every customers car unless they want to pay for new A/F which they never do ! Just slap the sealant on and by the time you've re fitted the hoses it's be set ok, try and reuse the ols gasket with it if poss, seals better i've found

Gasket paper and a scalpel? +1 I hate gasket compounds with a passion. Great as a quick fix but a right orrible mess to clean up afterwards. It's worth taking the time to flatten the surface of the stat housing if it's corroded and make a gasket.

If you use it properly and in the correct application RTV silicone is great stuff, you need less than you think andd it's ideal for flat waterway gasket surfaces. Clean the surafces to be bonded, apply a very thin layer of gasket goo, lightly oil the surface of the housing wait a short while untill the gasket goo just starts to skin off, then press down lightly with the housing, remove wait half an hour or so (before it has fully dried then bolt it all up together this way it's not glued together so you have a perfect seal, and if you need to you can remove it again without having dried curse word everywhere..
TBH I almost always use a thin smear of it even on a new paper gasket in such applications never had one leak yet! on an old engine there's almost always some surface damage on these types of components and you'd never know it had been used..
used correctly there's nothing wrong with it, it has just got a bad name by being squirted everywhere and anywhere by D.I.Y wallys much like polyester bodyfiller, used correctly it's brilliant stuff

The Internet, like all tools, if used improperly, can make a complete bo**cks of even the simplest jobs...

Frosty packet and a smear of blue hylomar, that'll seal it

I've used this: for everything except the exhaust manifold and headgasket Clean the surface well, I like to gently sandpaper them too, and apply to one of the faces (very little is just enough) leave for half an hour or something. I've probably done over 10 termostat housings, a few diff covers, fixed leaking rocker cover gaskets etc.. Never had a problem. (touch wood ) I've even glued a piece of alloy over a hole in a sump using it and sikaflex! Only a "temporary" solution of course... Edit - And it comes off easily enough too! ;D

I have some proper Loctite sealant for this type of thing, it cost 30 quid for a small tube. You can borrow it if you want, you're only up the road.
