89 Cavalier 32K - 2.0 - Auto - AC
Replaced radiator - thermostate - temp sensor in head the one with 2
Overheats with ac on or off. 70 or higher outside temp. Faster with ac
off because the radiator cooling fan never comes on. Replaced the 2
wire temp-sensor in head no change. The fan works with the ac on and
the overheating takes a little longer. Also the overheating is only
when the car is stopped at redlights or moving slow in heavy traffic.
When the car starts moving, more than 20mph, the temp comes down to
- What dose the temp-sensor in the head with 1 wire control.
- Are there 2 relays that control the fan. 1 for when the ac is on and
another for when the temp gose up with the ac off.
- One other problem - the speedometer has a pulsing squeak that is
always there ( have a 90 Cavalier with same problem ). Is it fixable
by removing the housing and oiling a part inside the housing. Got a
used housing for the 90 Cavalier, it is allot better, but it still
has the pulsing squeak (changed the speed cable on the 90 squeak still
