Ref. No.: 87-208-1
Corp. Ref. No.: 738105
SUBJECT:
INOPERATIVE COOLING FAN WITH HIGH A/C HEAD PRESSURE
MODELS AFFECTED: 1987 CENTURYS WITH THE LB6 2.8L MPFI ENGINE (VIN CODE W) AND C60 AIR CONDITIONING
Condition:
The engine cooling fan may not operate when the A/C head pressure is high, which could lead to insufficient A/C cooling, or an
overheated engine.
Cause:
The retaining ramp on the cooling fan pressure switch is backwards. This was changed in production early in the 1988 model year by first
using a tie-strap and then by changing the ramp on the switch.
