Featured Service & Repair Tech
Since diesel engines are typically operated in high load situations, its various components endure demanding conditions that necessitate a strict maintenance schedule. While diesel engines are known for the their ruggedness, strength, and long service life, these characteristics quickly disappear if routine service procedures are neglected. OEM recommendations are published with the intent of helping owners get the most from their vehicle and should be followed religiously.
1995 and older 6.5L GM diesels utilize an oil pressure sensor that doubles as a switch. It is not until oil pressure is built that the switch supplies power to the lift pump.

Does your clutch pedal need to hit the floor in order to avoid grinding gears in the ZF 5 speed? Clutch throw was an ongoing issue with both generations of F-Series pickups that used the ZF 5 speed manual transmission, however the bushing setup is much weaker on 87 to 91 model year trucks. While there are many areas to check, clutch pedal bushings are a good start.
