1998 Ford Windstar Oil in Coolant
Suggested Repair
Inspect the radiator, since the contamination may be transmission fluid from the cooler. If the radiator is not the source, pressure-test the cooling system for a bad head gasket, which is common on these vans. Also check the engine oil for coolant, which can damage the crank bearings.
Conversation Summary
The owner of a 1998 Ford Windstar reported oil in the engine coolant and asked for the possible source. One expert said the radiator could be involved and that the fluid might be transmission fluid. Another expert advised pressure-testing for a bad head gasket if the radiator is not the cause and recommended checking the oil for coolant to avoid crank-bearing damage. A later non-expert reply suggested a blown head gasket or cracked head and a sealant product. An unrelated comment about four-wheel-drive lights was also posted.
