Question about Jeep Grand Cherokee

1 Answer

My name is Alan:I am helping a neighbour with some over heating problems and coolant loss from a 99 5.7 litre motor. I have located the thermostat and replacing it with a new one. The hand book tells us we need to refill the radiator via a special method but does not explain how. Could the information be made available to us it would be much appreciated. Thanking you. Longy.

5.7L
1. Close radiator draincock. Hand tighten only.
2. Install engine block drain plugs, if removed. Coat the threads with Mopar® Thread Sealant with Teflon. WARNING: When installing drain hose to air bleed valve, route hose away from accessory drive belts, accessory drive pulleys, and electric cooling fan motors.
NOTE: It may be necessary to install a bleed fitting on the 5.7L engine.

3. Attach a 1.5 - 2 m (4 - 6 ft.) long 6 mm (1/4 inch.) ID clear hose to bleeder fitting

  • Plug Location (5.7L): Located on the front of the water outlet housing at the front of engine.

4. Route hose away from the accessory drive belt, drive pulleys and electric cooling fan. Place the other end of hose into a clean container. The hose will prevent coolant from contacting the accessory drive belt when bleeding the system during the refilling operation. NOTE: It is imperative that the cooling system air bleed valve be opened before any coolant is added to the cooling system. Failure to open the bleed valve first will result in an incomplete fill of the system.

5. 5.7L ENGINE - Install a threaded and barbed fitting (1/4 - 18 npt) into water pump housing.
6. Attach Filling Aid Funnel Tool 8195 to pressure bottle filler neck.
7. Using hose pinch-off pliers, pinch overflow hose that connects between the two chambers of the coolant bottle (2).
8. Open bleed fitting.
9. Pour the coolant (Refer to LUBRICATION & MAINTENANCE/FLUID TYPES - DESCRIPTION) into the larger section of Filling Aid Funnel (the smaller section of funnel is to allow air to escape).
10. Slowly fill the cooling system until a steady stream of coolant flows from the hose attached to the bleed valve.
11. Close the bleed valve and continue filling system to the top of the Filling Aid Funnel Tool 8195.
12. Remove pinch-off pliers from overflow hose.
13. Allow the coolant in Filling Funnel to drain into overflow chamber of the pressure bottle.
14. Remove Filling Aid Funnel Tool 8195. Install cap on coolant pressure bottle.
15. Remove hose from bleed valve.
16. Install fitting into thermostat housing. Coat the threads with Mopar® Thread Sealant with Teflon.
17. Start engine and run at 1500 - 2000 RPM for 30 minutes. NOTE: The engine cooling system will push any remaining air into the coolant bottle within about an hour of normal driving. As a result, a drop in coolant level in the pressure bottle may occur. If the engine cooling system overheats and pushes coolant into the overflow side of the coolant bottle, this coolant will be sucked back into the cooling system ONLY IF THE PRESSURE CAP IS LEFT ON THE BOTTLE. Removing the pressure cap breaks the vacuum path between the two bottle sections and the coolant will not return to cooling system.

18. Shut off engine allow it to cool down for 30 minutes. This permits coolant to be drawn into the pressure chamber.
19. With engine COLD, observe coolant level in pressure chamber. Coolant level should be within MIN and MAX marks. Adjust coolant level as necessary.

Hmedmy Audi a4 1996 2.6 litre is over heating and leaking coolant, i dont know what the problem is


More than likely they're related. First locate the leak - hose, waterpump - repair the leak & I suspect your overheating will stop. Note; you might consider replacing thermostat also, they damage easily when overheated.

Losing coolant about 1.5 Lt per short trip , had heat now I have very little even on high , I'm thinking heater core ??? Not sure where on a 93 is the core??? It's a 1.3 thanks


The core is located inside the heaterbox, this is located inside under the dash but i would locate the leak first, a bad heatercore will leak inside the carpet or leak out the drain, if its full of coolant then you may have other problems, try reving the engine and see if the heat gets hotter, this may be due to a bad thermostat or plugged core, the core can be flushed with a waterhose, remove the hoses going to the heater core and use the hose to flush it, go a few times both ways to flush out, but you still have the coolant loss problem, you will have to preasure test the cooling system and look for a leak, hopefully it not bruning it, it exhaust gets into the cooling system it will cause loss of heat depending on how big a leak and would explain the coolant loss, theres a test that can be done to see if its exhaust entering the cooling system. hope this helps, good luck.

Trying to find thermostat can you help


Not Familiar with vehicle but can give you some basic info.The Thermostat could be on top or bottom of engine.It is in a bell shaped housing,follow the Hoses from the Radiator.If you get heat when the Engine shows warm and you don't overheat it's not the Thermostat.If your not getting heat check the level of coolant first.If coolant is low you wont get heat or low heat.If your overheating it could be other problems,Blown Head Gasket.Clogged Radiator,insufficient coolant.Good Luck.

99 Oldsmobile Alero coupe running hot


well, usually in this case, if your coolant resovior is full and you are still holding psi in your system, it is a bad thermostat. what the thermostat does is when the engine block heats up, the coils of the thermostat expand and let coolant through to cool the engine block. so what might be happening is your thermostat is bad, and not letting coolant through, which will cause your motor to over heat.

99 deville head gasket leak?


A head gasket leak is usually indicated (among other things) by continous overheating of the motor, and subsequent loss of coolant.
It can also be indicated by the presence of engine combustion gas bubbles in the coolant resevoir.
Ensure the coolant system has no external leaks, such as faulty hose/s, radiator etc.

Ensure motor tune or other motor mechanical condition is not the cause of overheating.
I assume the motor is actually running hot.

Check cooling fans are operating ok (as necessary when car warms up):- if not check
1) fuse,
2) relay operation,
3) heat sensor switch.

Check/replace the thermostat,
Check the coolant pressure cap is serviceable & of correct rating,
Ensure cooling system is correctly filled, bleed off any airlocks as necessary when re-filling,
Ensure radiator hose on suction side of waterpump is not collapsing at engine revs above idle (due softening),
If the motor has been severely overheated, the head gasket could be blown - look for combustion gas bubbles in the coolant resevoir.

Replace the engine thermostat, it is probably stuck open.

It is located where the top radiator hose enters the engine block and is supposed to close when the engine is cold, thus prevent coolant from going to the radiator while the engine is heating up.

At engine operating temperature, it opens up, sends the coolant to the rad, and keeps the engine coolant at that constant temperature.

99% of the time, this is the culprit.

The other 1% could be a clogged/partially clogged heater core, or a busted heater core (accompanied by a coolant leak/loss over time) which fogs up the windows even more when the heater is on defrost.

Thermostat replacement is an easy, quick job and cheap.

Heater core replacement is a little bit more time/money consuming

Over heating/ loss of coolent


If you are not loosing coolant on the ground. You may have a problem of a bad intake manifold gasket or worst a bad head gasket. The two things to look at are coolant in your oil, manifold gasket. Coolant out the exhaust, head gasket.
