To install:
  1. Clean all gasket mating surfaces.
  2. Guide the water pump and new gasket into position while connecting the bypass hose to the pump. Tighten the water pump bolts to 30 ft. lbs. (40 Nm).
  3. Install the bypass hose clamp.
  4. Spin the water pump to ensure the pump impeller does not rub against the timing chain cover.
  5. Coat a new O-ring with coolant and install it to the heater hose coolant return tube.
  6. Install the coolant return tube to the engine. Ensure the slot in the tube bracket is bottomed to the mounting bolt. This will properly position the return tube.
  7. Connect the radiator hose to the water pump.
  8. Connect the heater hose and clamp to the return tube.
  9. Install the water pump pulley and tighten the bolts to 20 ft. lbs. (27 Nm).

How to change a heater core in a 93 jeep grand cherokee


When I turn my heater on, after my 1993 Jeep Grand Cherokee has warmed up, there is a dusty, watery smell for a few minutes, then it goes away. Also, it doesn't put out as much heat as I think it should. I don't think the heater core has a leak, because I always seem to have the same amount of coolant in the radiator and the heater core is not leaking on the inside of the truck.

My 1993 Jeep Grand Cherokee with a 4.0 liter 6 cly, will start up but not stay running, I've replaced the fuel filter and rotar, any suggestions?


at the front of your engine there's a fuel pressure regulator and it has a small vacuum hose connected to it. after you start it and it stops, pull off the vacuum hose and see if gas comes out of it? if so your fuel pressure regulator is bad! i changed mine and it was easy only needed a snap-ring pliers to take it out. new pressure regulator comes with a new snap-ring in the box! hope this helps!!

Just replaced leaking radiator in my 2001 Grand Cherokee,I can hear antifreeze running through the heater core,heat works fine on # 2 fan setting anything higher air starts to cool,got to be the heater...


Hi

You need to bleed the heater system, suspect you still have an air lock in it.

Slacken off outlet side of heater, hose clip. and run engine at 1000rpm, pull off the hose, once the flow is coming out constant, refit hose and tighten clip, and top up coolant.

Good Luck !

A FixYa would be appreciated !........ Thanks....John

Heater hose coolant return tube


Yes you can remove the tube if its a V8. If its an inline 6 cylinder you have to remove the pump in order to repair the heater pipe.

1996 jeep grand cherokee limited v8


With the water pump removed, you have to heat the body of the water pump. There is a O-Ring that seizes the tube into the water pump. Sometimes you can just loosen the bolt and heat the pump with it still bolted up the engine. Use some pliers to wiggle the tube while pulling the tube. When you put it back together replace the o-ring and add some rtv sealant around the o-ring too. This helps the seizing problem. Hope this helps
