TO:
ALL CHEVROLET DEALERS
General Motors has determined that certain 1988-89 K30 series trucks with 7.4L V8 engine and engine oil cooler option may have oil cooler line/filter
adapters that were machined incorrectly. These adapters allow oil to by-pass the engine oil cooler and/or the engine oil filter.
To correct this condition, it will be necessary to replace the engine oil cooler line/filter adapter. In addition, new oil and oil filter will be installed.
