Richardman, I'll be interested to hear how you get on with the thermostat replacement and whether you need to remove the alternator to get access to the bolts (it looked that way to me). I planned to change my thermostat last weekend but decided to postpone after seeing the tight access to the bolts. It didn't help that I initially made a wrong assumption that the 'stat was located in the housing where the top radiator hose attaches to the cylinder head (RHS as looking at engine). After removing the housing I found it was empty :unsure: Still, with the housing off, it made the coolant temp sensor change much easier :) BTW, this is my first post so thanks to all contributors to this great forum - I've been a reader for some time but having now purchased an '02 115BHP Ghia I expect to become a more active member.
