I'm experiencing the following problem and am not sure what to start
checking for the solution.

I'll be driving along and the red coolant light will start flashing. I'll
stop and notice that the expansion tank is low on coolant, but the overflow
tank (behind the license plate) is filled to above the level of the cap.

I fill the expansion tank with water, and empty the excess from the overflow
tank. This solves the problem for about a week. There does not seem to be
any event or type of driving that precipitates this - except that usually 1
day before the van will start registering high temps (above the red led).

Any ideas on what to look for?

Also - anyone with an '88 with A/C : where does relay 53 go? I wonder if I
plugged it into the wrong place. It does not seem to go where the Bently
manual states.

Thanks
