How do you replace the water pump on a 1991 4.0l ford explorer?

Answer 1

I just changed my daughter's Explorer water pump and fan clutch. What a pain - mid summer - over 100 degrees. Here are the steps / lessons learned; 1) Park the vehicle in a flat area, near water source, and in the shade. 2) Obtain the pump - it cost me approx $66 via O'Reily Auto Parts Store, gloves, rags, coolant - $10, metal sharp putty knife, and gasket $4. 3) Also rent or borrow a fan clutch / pully remover - A MUST! 4) Obtain a socket set (metric and SAE), open end wrenches, rags, oil pan to catch water, and a plastic bowl to store bolts and nuts. 5) Remove the water hoses - top and bottom - will get very messy - use the oil pan to catch most of the water, 6) Using the fan clutch tool remove the fan clush and fan away from the pully - turn very large nut in front of pully. 7) once fan is removed - remove the fan shroud with a nbr 10 metric size tool. 8) pull all three out at same time - upwards. 9) remove surpintene belt with large socket and use gloves - you will pinch yourself without 10) remove pully - 4 bolts and store in safe location 11) pump has 10-12 botls - some hard to see. Use the new pump to account for every bolt. 11) once all bolts are removed pull pump and return to store for core refund 12) with a metal puddy knife remove all old gasket from engine - use rag to clean 13) spray all bolts with WD40 to lubricate and lossen crus from parts 14) install new pump - finger tighten all bolts first and then gently tighten in a cross configuration method 15) replace all parts in reverse order.
