Thermostat Housing Removal

Post by trussers »

There has to be an easier way :-?

My 1098 overheated this week - top of rad hot, lower cold. Aha...thermostat I said. Easy peezy, three bolts, little tap, out with the old in with the new.

Little taps turned into big taps, WD40 and then I gave up and read posts here. Toilet cleaner has been sprayed, still not budging. My blood pressure is now through the roof, and the advice on another posting on here to use a cold chisel and belt the thing is probably the way I will now go, as the old housing is now stuffed! But...angry as I am, swinging a lump hammer at a cold chisel does not sound such a great move, and surely risks cracking the head? If this is the way to go, where is the weak point to whack it?

On other BMC's I have had this is a five minute job........any advice hugely appreciated, but I should warn you...I am a novice, so please treat me like an idiot, and you will not go far wrong :-)

Cheers

The rad is SUPPOSED to be hot at top/cold at bottom. Nothing wrong with the stat I suspect. The removal problem is simply down to age - the alloy housing rots against the steel studs - and grips them like h3ll... Heat and proper release oil (so NOT WD40) - and then try to unscrew the studs from the block - using two nuts. When you refit - run a drill bit down the holes in the stat cover to open them up slightly and smear everything with lots of grease....
