Tip & How-To about 1987 Jeep Wrangler

Replacing the water Pump

Here's a step by step to remove and replace the water pump on your Wrangler.

Be advised, all 4.0L engines, some 2.8L engines and some 4.2L engines have a reverse rotating water pump. You can ID these from the word REVERSE or REV imprinted or cast on the housing and/or fan. There will also be an 'R' stamped into the impellor.

Make sure your replacement pump is the correct type, If not, expect some major turmoil.

The procedure:
1. Remove negative battery cable
2. Open radiator valve - drain cooling system
3. Remove cooling fan and shroud
4. Remove belts (see my tip on serpentine belts if needed)
5. Remove water pump pulley from hub
6. Remove hoses from water pump
7. Remove accessory brackets from the water pump.
When removing the P/S pump and/or AC compressor, leave the hoses attached and move them out of the way.
8 . Remove the remaining bolts and detach the water pump from the engine. The bolts are three different lengths. Make note of where they came from.
9. Compare the new and old pumps. Make sure they match.
10. Scrape off the old gasket material.
11. Apply a thin continuous line of RTV High Temp sealant to the water pump side of the gasket.
12. Put a couple bolts through the pump to hold the gasket in place and mount the gasket.
13. Apply Another coat to the other side of the gasket.
14. Attach the pump to the engine. Screw the bolts in finger tight.
15. Attach the remaining bolts.
16. Tighten them up in 1/4 turn increments.
17. Re-attach all the stuff you removed
18. Refill the coolant, adjust belt tension.
19. Run the engine and check for leaks.

Hope this helps
Mike

replace fuel pumpand moddual on a 2001 jeep wrangler sport 4.0l in side tank assembly


Fuel Pump Removal & Installation To Remove:
WARNING
The fuel system is under constant pressure, even when the engine is off. This pressure must be released before servicing the fuel pump module.
  1. Drain fuel tank and remove the tank.
  2. Thoroughly wash and clean area around pump module to prevent contaminants from entering tank.
  3. The plastic fuel pump module locknut is threaded onto fuel tank. Install special tool #6856 to fuel pump module locknut and remove locknut. The fuel pump module will spring up when locknut is removed.
  4. Remove the module from fuel tank.
To Install:
CAUTION
Whenever the fuel pump module is serviced, the module gasket must be replaced.
  1. Thoroughly clean locknut threads and mating fuel tank threads. Use a solution of soap and water. Do not use carburetor cleaner to clean threads.
  2. Using new gasket, position fuel pump module into opening in fuel tank.
  3. Apply clean water to locknut threads.
  4. Position locknut over top of fuel pump module.
  5. Rotate module until arrow is pointed toward front of vehicle (12 o'clock position). This step must be done to prevent float/float rod assembly from contacting sides of fuel tank.
  6. Install special tool #6856 to the locknut.
  7. Tighten the locknut to 55 ft-lb (74 Nm).
  8. Rotate fuel filter/fuel pressure regulator until its fitting is pointed to 10 o'clock position.
  9. Install the fuel tank.

When removing the P/S pump and/or AC compressor, leave the hoses attached and move them out of the way.
8 . Remove the remaining bolts and detach the water pump from the engine. The bolts are three different lengths. Make note of where they came from.
9. Compare the new and old pumps. Make sure they match.
