Did you check the coolant level in the main pressure tank? The system may be low due to a bad pressure cap allowing coolant to burp out when warm and then not sucking it back it. When cold, lift the engine cover before starting the engine so you can see. Then start the engine and immediately go back to see the level in the main tank. If it is low, then you need to find out why. As the coolant warms up it is expanding so it will cover the sensor probes and turn the light off.

However, I have a new potential problem (i.e. that's to say I don't know if it is a problem or just a nuisance) with the water temperature indicator light on my '87 Westy. Normal operation: when I start engine from cold, light flashes for several seconds & then goes out (it behaves this way most of the time) Occasionally: light continues to flash (I've only waited about a minute). If I switch engine off and on again, it behaves normally. Occasionally (after switching engine off & on again); light comes on again, a little later (perhaps half a minute later) and continues to flash. If I switch engine off and on again, back to normal operation. This only seems to happen first thing (morning, not particularly cold here in northern CA) and does not come back later in the day. I can then drive all day (well, use the van for trips up to 50 miles, that's as far as I have gone recently, at up to freeway speeds) without the light flashing again. Coolant level is normal (i.e. b/w the full/empty marks on the expansion tank), no recent coolant changes or leaks. The (analog) temperature gauge behaves normally, starting from cold and settling just below midpoint marker under normal use. Engine is stock 2.1l and has 112k. Any ideas?? Thanks, Mike '87 Westy
