Dear Friends,

Since I replaced my coolant reservoir, the temp gauge on my 83.5 has been
acting screwy: flashing warning light goes on and off, temperature gauge
shoots up, then drops down etc. I do think the engine is actually running
hot, but not as hot as fast as the gauge sometimes indicates.

The sensor in the old tank was cracked, so I replaced it with one from my
parts car, on which the terminals weren't quite as thick (hence, bad
connection perhaps?). Now I am wondering whether the sensor has anything to
do with the temperature gauge or measures only  coolant *level*.

Also, a flashing light in the temp gauge means either low level OR
overheating, right?

Will a new sensor (which I have already) solve my problems?

Do I need a new Temp 1 sensor?

Please send your thoughts to my personal address. Thanks. And thanks for all
the advice on the O2 sensor light. I finally got it to go out.

Woody
