Larry,

When I first got my 88 GL I had a cooling problem. My mechanic was
checking the rig over forme, had the engine idling after a quick run
around the block, when the cooling system literally blew the expansion
tank level sensor completely out of the tank!! We were all surprised!
That indicated at first that the pressure cap was faulty, and wouldn't
open to bleed expanded coolant over to the over flow tank.

I had a new cap on hand, so it wa sinstalled, and the coolant level
sensor was re-installed. Warmed up the engine and bang, the sensor blew
out again.

Upon checking, it was obvious that the threads on the sensor and tank
were not good, so I ordered a new tank and sensor.

New tank and sensor installed, new pressure cap installed, warmed the
engine, and BANG! coolant sensor was again blown out of the expansion
tank. Really puzzled now, I got a new thermostat for the system,
mechanic installed and rand the engine. No more problems. Been good ever
sense, and all that happened 60,000 miles back.

For what it's worth............!

Regards,

John Rodgers
88 GL Driver
