How do you change the thermostat. Its a 1980 hl auto with a 1275cc engine. I cant seem to get at the thermostat because the housing is attached. How do you get it off. I've undone the 3 bolts but it still wont budge

Any help much appreciated.

Assuming you have taken off the bracket for the radiator too. Then its a case of wiggling the housing until it comes clear. The gasket can be holding it all together

a light tap with a wooden mallet can help

They can really stick themselves to the studs, be careful not to lever something between the iron cyliner head and the alloy housing to pry it up, a few small taps should work!

Thanks. I have taken the bracket off but there is a a square cover over the housing and I cant get this of.

Can you post a picture? I'm not sure of any square cover but I'm not familiar with auto's

I cant get a picture atm as the car is at a lock up as its being restored. Wont be able to get one till the weekend and it is an auto.

I am sure the theromstat housing is the same as a manual, ie round-ish. When I was servcing a friends car for the first time after he bought it, I ended up breaking it away in bits it was that stuck, but I had a spare in my garage I used that was in good nick. It must have been the original, it was very warped and backfilled with silicone as a temp fix  / bodge.

Thanks for the help

Are you talking about the engine steady bracket?

Can almost guarantee its just the bolts in the thermostat housing have rusted, give it a good soaking in penetration oil and give it a few taps till it comes loose.

 

In a few cases i have had to cut the aluminium housing, round the bolts to get it off.
