Thanks for the reply Stuart.

I've looked at the pic of the coolant light, and I dont think it's
that one. Its on the LHS of the instrument panel, and is roughly
recrangular, with the bottom half lit up. Unfortunately its only
intermittant, and I can't get it to go right now to draw a diagram!!

Will try to shine a torch or something on it, hopefully I can see it
in order to draw a picture.

Any more suggestions appreciated!

Phil
