I have a 92 Ford Explorer. I recently thought I had a leak from the water pump. I changed the pump to find that the leak was not the pump but coming from something else. The hoses seem fine but it is still leaking somewhere. I can see the coolant drip down but can't pinpoint where it is coming from. It also makes a hissing sound when hot. Could this be the engine. Thanks in advance for your reply.

Coolant will normally leave a white stain when dried. The hiss is quite possibly the leak. Look for stains above the waterpump. Usually the highest piont will be the leak.

Good hunting. :)

Suggested Repair

With the engine hot, trace the hiss and look for white dried coolant stains, especially above the water pump. The highest stained point is usually the leak source.
