Well... fixed my thermostat and changed the gearbox oil gearbox feels smoother and its less noisy, haent tried to throw the gear in yet becauseeeee when i fitted the new thermostat with was the problem when engine was cold all the time( thanks peeps for the help) when i got it all together nippy the bolts up on the housing one of the studs SNAPPPED now ive only got one nut holding it on, but its leaking the tiniest bit and i see a little bit of steam coming off it, anybody thought about extracting the stud and put a bolt in its place? yous reckon i could drive a 70mile round trip to pick my new wheels up with this 1 nut on the thermostat housing?
