    So. I had thermostat issues. Changed it last week and fixed it, all was well! Cool! Noted that I was loosing about a cupful of water a day, it was dripping from
    The housing, culprit bein me using An old gasket (yes i know). Anyway, I go to fix tonight and this happens:

    So it's sheared off leaving the screw still in there. Will the garage be able to remove this You reckon? It's in a right tricky area :(

    If you remove the plastic housing can you get a grip of the bolt shank?

    If not you'll need to drill it and use a stud extractor.

    It sheared because you over tightened it the hex bolt or am i not seeing this clearly ... ?

    You could always weld another bolt onto the end of the shank if there is access.

    You might not need a drill, Now its snapped it wont have any tension on it, so if you can get a grip on it it'll just wind out.

    The thermostat housing is aluminium? Only the elbow is plastic...

    Take the plastic housing off and see if you can grip onto the remains of the snapped stud.

    Ok will try that. And then B and Q for another screw, they should stock something similar I hope.

    Yeh thats a coolant drain.

    B&Q should have a suitable machine screw. I think its an M6.

    If you can't grip with anything use a flat head and try loosen it by tappin it anti clockwise, it's not so bad as you sheered it tighten it as f this happened when loosing it you'd have no chance, although I think the bolt is a unusual side as I tried getting one myself
