TECH TIP FOR JULY, 1992

ON 1981-87 CHRYSLER "K" CARS, HAVING A 2.6L W/O FI, IF YOU
EXPERIENCE REPEATED ALTERNATOR FAILURE, CHECK FOR A SHORTED
COOLING FAN RELAY. THIS WILL CAUSE THE DIODE TRIO IN THE
ALTERNATOR TO FAIL PREMATURELY.

ON 1990 CHRYSLER VEHICLES WHICH MAKE A CHIRPING OR SNAPPING
NOISE AT THE FRONT OF THE ENGINE, IT IS POSSIBLE THAT THE
ALTERNATOR MOUNTING BRACKET IS MISALIGNED AND IS CAUSING THE BELT
TO " WALK " ON THE SERPENTINE PULLEY.

TO CHECK, SPRAY WATER ON THE GROOVED SURFACE OF THE BELT
WHILE THE ENGINE IS RUNNING. IF THE NOISE SUBSIDES AND THEN
RETURNS AS THE BELT DRIES, BRACKET MISALIGNMENT IS PROBABLY TYHE
PROBLEM. IF THE NOISE DOES NOT SUBSIDE THEN THE ALTERNATOR BELT
IS NOT THE PROBLEM.

DO NOT USE BELT DRESSING, SILICONE SPRAY, OR BRAKE FLUID AS
A SUBSTITUTE FOR WATER.THESE MATERIALS WILL ACT AS A LUBRICANT
AND TEMPORARILY MASK THE PROBLEM.

IF YOU DETERMINE THAT IT IS PROBABLY BELT MISALIGNMENT WHICH
IS THE PROBLEM, CONTACT A CHRYSLER DEALER FOR A COPY OF THEIR
SERVICE BULLETIN DATED SEPTEMBER/1990, AS THE REPAIR IS TOO
DETAILED TO BE OUTLINED HERE.
