My 4.0 explorer is over heating. A shop replaced the water pump and thermostat. Still overheating. Cap and both hoses are cold. Fan is working, heater blower is working. Water in radiator is not hot.

Something is plugging it, if both hose of the cooling system is cold to touch something going on with the water pump. Or something is plugging the cooling system, when you feel the radiator hose make a comparison to it with the heater hoses

The waterpump flow has to be tested, another easier way is remove the thermostat, and if it overheats quickly, and both radiator hose are cold to touch, you have a blockage in the hoses or the waterpump has issues

This is an involved process but straight forward. However, I recommend you get a good repair manual with step by step instructions and pictures to help identify parts. For me to try and explain it via the Internet allows too much room for error.

If you're finding a cream-colored goo under the oil fill cap? That is typically condensation from many short trips. The moisture comes in through the PCV system and doesn't get warm enough to vaporize and burn off. I get that at times on my '88 Grand Caravan after making numerous ten-mile trips to town, but not when regularly making a 30-mile trip once a week.

The fan clutch is threaded onto the water pump shaft. This is a LEFT-HANDED thread. Ford has special tools for removing the fan from the pump, but you can remove it another way. It is much easier with a helper.

Use a large wrench - an adjustable will usually work if it is not too thick. Fit the wrench to the large hex on the rear of the fan clutch. Have a helper wedge a long screwdriver between two of the bolts holding the pulley to the water pump. Tap the end of the wrench in a clockwise direction with a medium sized hammer. After a few tries, it should break loose, and then can be turned off by hand along with the fan.

Alternatively, you can do this with the belt installed to keep the pulley still, but some of the time, the belt just slips, and makes it difficult to break loose.

Hope this isn't too late, and is of some help.

Ask them if it is getting both spark and fuel to the engine. One will be missing.
