What was found
OIL COOLER CRACKED AT OUTBOARD FLANGE, AT BAFFLING MOUNT. THIS IS THE TENTH OIL COOLER ON A/C THAT OUR REPAIR STATION HAS SEEN WITH A CRACKED OIL COOLER IN THE EXACT SAME LOCATION. MFG HAS AN OPTIONAL SB22-71-03 BAFFLE MODIFICATION THAT SUGGESTS THAT THE BAFFLE BE MODIFIED TO PREVENT THIS PROBLEM. MY SUGGESTION IS THAT THIS SB BE MANDATORY AND/OR TIED TO AN AD TO PREVENT THE OIL COOLER FROM CRACKING AND CAUSING A POSSIBLE OIL LEAK.
