Transmission Cooler

The cleaning process of oil cooler repairs must always keep foreign material out because any entry into oil or coolant passages can result in engine failure. Placing the vehicle on a hoist in NEUTRAL while emptying the cooling system should be the first step. First disconnect the two quick disconnect oil cooler coolant tubes before removing and discarding the oil filter. The next step requires removal of the oil cooler mounting bolt. A professional inspection of the oil cooler tube assembly should occur when metal foreign materials are detected within the cooling system. Begin by installing the oil cooler together with its tube assembly and mounting bolt before tightening to 35 Nm (26 ft. lbs.). Install the new oil filter by applying clean engine oil to its seal then secure it with half a turn when the gasket makes contact with the sealing surface. Connect both quick disconnect oil cooler coolant tubes before filling the cooling system while performing a bleeding operation.

Cleansing procedures are necessary during oil cooler servicing and maintenance because contaminating particles that infiltrate oil or coolant channels would cause engine breakdown. The first step involves placing the vehicle in NEUTRAL position on a hoist and conducting a cooling system drain. Detach the quick disconnect oil cooler coolant tubes before you eliminate the oil filter and dispose of it. The next step should involve removing the mounting bolt of the oil cooler. The presence of metal or aluminum foreign material in the oil cooler indicates the need to diagnose mechanical problems through cooling system examination. The oil cooler and tube assembly passes inspection before you reinstall them while tightening the mounting bolt to 35 Nm (26 ft. lbs.). Place the new oil filter on the housing while applying clean engine oil to its seal and then tighten it 1/2 turn after the gasket touches the sealing surface. After reconnecting both quick disconnect tubes then proceed to fill the cooling system and perform a bleed process.

Services to the oil cooler require clean conditions to avoid foreign objects from entering the oil or coolant pathways because engine failure may occur. The first step should position the vehicle in NEUTRAL mode on a hoist then drain the cooling system. You must first disconnect the two quick disconnect oil cooler coolant tubes before filtering away the old oil filter. Providing service to the oil cooler starts with removing its mounting bolt. An inspection of the oil cooler assembly along with its tubes must occur when metal or aluminum pieces are discovered in the coolant. Position the tube assembly with the cooler and fix it by torquing the mounting bolt to 35 Nm (26 ft. lbs). Befo re tightening the new oil filter install a filter layer of clean engine oil on the seal before setting a 1/2 turn of torque when the gasket achieves surface contact. Connect both fasteners which link the oil cooler coolant tubes then start filling and bleeding the cooling system.
