Q: How to replace the oil cooler in Ford Expedition?
A: To replace the oil cooler in some V8 models, disconnect the oil and coolant hoses. Pull the cooler from the block adapter. If also removing the oil cooler adapter, remove its bolts. Clean the block and adapter, then install the adapter with a new gasket. Clean the adapter and cooler's sealing surfaces and install new O-rings. Apply thread-locking compound to the threaded tube and tighten it. Finish by installing a new oil filter, refilling the cooling system, and checking for leaks.
