Make sure that all the air is out of the system. One of the best ways is to start filling from the top and remove the bottom hose. Let it do this for about 1 minute then attach the bottom hose. stop the water flow and squeeze the top line a couple of times and look for air bubbles

Coolant isn't circulating in the engine of a Jeep 2002 Grand Cherokee V8. Radiator was just replaced as well as the water pump and thermostat.


Hi Jonny, While the engine is cold the thermostat will be closed, allowing coolant circulation around the engine block and cylinder head but not through the radiator. Only when the engine has reached normal operating temperature will circulation be noted in the radiator. A good test is to remove the thermostat while the engine is cold , start the engine with the radiator pressure cap removed and observe flow. If as I suspect it is there, refit the thermostat and check the heat gauge. If all remains well there is no problem. If the engine overheats replace another thermostat. If there is no circulation with the thermostat removed, there is a blockage in the cooling galleries of the engine. If chemical flushing does not clear it, it will require disassembly of the engine with careful step by step inspection at every stage. If the cylinder head(s) had been removed I would suggest making sure of the galleries not being blocked by installing the gaskets incorrectly. Regards John

What causes water blow back in 1999 4.7 grand cherokee after starting


Sound like a head gasket is leaking. The coolant is leaking from the water jacket through the failed gasket in to the engine crankcase. The "blow back" is caused by the combustion inside the cylinder to leak into the water jacket, pressurizing it.
Drain the oil immediately and do not attempt to run the engine until you have the gasket replaced. Water in the oil will destroy the engine beyond repair.

2001 Jeep Grand Cherokee Limited v8 4.7 with 155,000 mi. It recvently began burning oil and blowing white smoke.


Check the water to see it there's oil in it ...and...check the oil to see if it has water in it or if it's higher on the dipstick or not.

Sounds like a blown head gasket or cylinder rings.

How to replace a fuel pump on a 1994 jeep grand cherokee?


I'm assuming that your Jeep have a 5.2L V8 engine (as mine), then check this procedure...

Grand Cherokee 5.2L Engines
(see Figure 6)
  1. Disconnect the negative battery cable.
  2. Open the radiator valve and drain the cooling system.
  3. Remove the cooling fan and shroud as an assembly.
  4. Remove the accessory drive belt.
  5. Remove the water pump pulley from the hub.
  6. Disconnect the hoses from the water pump.
  7. Loosen the heater hose coolant return tube mounting bolt and nut and remove the tube. Discard the O-ring.

Fig. 6: Water pump mounting bolt locations
  1. Remove the water pump mounting bolts.
  2. Loosen the clamp at the water pump end of the bypass hose. Slip the bypass hose from the water pump while removing the pump from the engine. Discard the gasket.
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).
  10. Install the accessory drive belt.
  11. Install the cooling fan and shroud.
  12. Fill the cooling system.
  13. Connect the negative battery cable.
  14. Start the engine and check for leaks.

Other details can find in your repair manual ZJ-Secc-7-Cooling-System

Hope thats help.

How to replace timing cover gasket on a '97 jeep grand cherokee


Pull the alternator brackets and front engine brackets off until you get to the water pump. You will also need to remove the fan shroud and then the fan. Remove the water pump and then you will see an aluminum cover and that will be your timing cover. remove the cover and clean all the gasket off the engine and the cover. use a razor blade, and make sure there in no oil or grease on the parts where the gasket lies. Put your gasket on, bolt the cover back on with the new gasket and repeat the teardown process in reverse.

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.
