How to Install & Remove a 60 Series Detroit Oil Coolerby Andrea Walk
Detroit Diesel released its 60 Series truck motor in 1987. This inline six-cylinder, four-cycle diesel engine for big rigs was one of the first engines to ever feature an overhead camshaft. The oil temperature in the 60 Series can range quite high. As a result, an oil cooler (or oil circuit kit) is used to help cool the oil. The oil cooler is a small radiator-like unit that mounts to the engine. It takes about one to two hours to change an oil cooler on a 60 Series engine.
Raise the hood on the Detroit diesel.
Locate the oil cooler on the right-hand side of the engine block. It is rectangular in shape.
Use the socket set to remove the oil cooler housing from the side of the engine block.
Unscrew and remove the old cooler thermostat and seal rings. Slip the new seal rings over the replacement thermostat (which comes with the oil cooler kit) and then screw the new thermostat in.
Remove the core element from the inside of the cooler housing and the gasket that lies on the rim of the cooler housing.
Remove the cooler hose and the oil supply tube from the oil cooler filter beneath the core element by hand.
Install the new cooler filter inside the cooler housing along with the new core element from the kit, then reconnect the oil supply tube and cooler hose to the new core.
Place the cooler housing with the installed parts to the side of the engine block; insert the retaining bolts and tighten them with the socket set.
