Thermostats - K series

[Ben_SS]

Are these a standard part I can pick up in a motor factors?

[ewenm]

Should be, I've got one sat in a MG-Rover branded box at home. A good motor factor should have original or equivalent parts.

Yes.

I got a 82 degree one after a bit of a search through a book.

Top tip - drill a couple of 4mm holes in the thing so that you can bleed the system more easily and it's never really shut. OK, the car will warm up more slowly. Not really an issue.

: Hmm, I'm not convinced...

 

I've note had much problem bleeding my (heaterless) k - and all of the recent stats I've fitted already have a small (2mm-ish) hole. My current stat has a much larger hole with a bobble-valve and on a cool/cold day, the engine runs some 10-degrees cooler than the stat rating.

 

Might just be a duff stat, opening too eagerly, but my suspicion is that the 'bleed' hole is allowing enough flow for the (rather efficient) Radtec to overcool the engine.

Another data point - when I fitted my new engine I installed an 82 stat (from Eliseparts) . In this I drilled two 3mm holes. Very easy to bleed down (but then I have no heater), and the engine sits at 80C , even yesterday in the heat. It does take a little longer to warm up though. I have the standard Ali rad.

additional holes for bleeding, or none for cooling?

To add, I would drill 2 small holes in it 3-4mm. 😬
