Car had not been getting up to temp and rarely going out of the blue so i fitted a new thermostat today and now the damn thing leaks!!

I removed the old one which was stuck open and cleaned all the mating surface,fitted the new rubber seal and bolted it all back up and its leaking from around the top mounting bolt.....any advice??

if you installed it correctly and it leaks then it is faulty...

Sounds simple but you have tightened all of the bolts correctly?
I have tightened all the bolts but did not want to overtighten them as they are only small and i'm scared of snapping them....did them up as tight as i dared.

Anyone know the torque settings for these bolts?

Got it off someone on ebay and it was brand new in box for £40.Don't think its a genuine BMW one.

Hello mate the ones from E*** C** P**** are absolutely useless, its worth paying the extra for a genuine BMW one mate. I had the same problem as you as well as the stat working it self loose from the housing. The BMW one is so much more peace of mind. Hope that helps mate.
