Where is the engine coolant drain plug on a 98 expedition?

The engine coolant drain plug location on a 1998 Ford Expedition depends slightly on the engine type (4.6L or 5.4L V8). However, it's generally found on the lower radiator hose, near where the hose connects to the engine block.

It's not typically a separate plug on the engine block itself like some vehicles. Instead, you'll drain the coolant by loosening the hose clamp on the lower radiator hose, carefully lowering the hose, and letting the coolant drain out. You may need a drain pan to collect the coolant.

Before attempting this:

* Consult your owner's manual: This is the best source for the exact location and procedure for your specific vehicle.

* Allow the engine to cool completely: Hot coolant is under pressure and can cause serious burns.

* Use appropriate safety gear: Gloves and eye protection are recommended.

If you can't find it easily after looking at the lower radiator hose connection, consult a repair manual specific to your year and engine size, or seek assistance from a qualified mechanic.
