SOURCE: 2000 jeep grand cherokee is leaking antifreeze

Have a shop pressure test the cooling system, this will make the leak easier to locate, if I have to guess I would go with a leaking water pump.

You may have a stuck closed thermostat or the impeller has failed on the water pump.

Replace them both. You never trust a stat that has gotten hot, and there is no sure fire way to test. You can take it out, put the car back together and see if the engine still gets hot to determine if it's the stat, or the water pump, but once you do all that, you might as well just replace them both.

You also need to make sure the radiator is not all slugged as well, and make sure the radiator cooling fans are both working.

There is a cooling fan relay that is prone to failure as well. Mine did in my '03 Jeep Cherokee. It's located behind the right headlight, and requires that you remove the headlight, drill a hole in the plastic shield, and replacing the relay. You can get a new one at the auto parts store.

Everyone automatically assumes that oil and water mixing means a blown head gasket or cracked engine block. Of course common sense is usually not that common. Oil in coolant is a different problem than coolant in oil. The former is a low pressure leak, and could indicate only an intake manifold gasket. It could also be an early or small head gasket leak. Coolant in oil is usually a cracked block or torn head gasket, and has concomitant symptoms of white exhaust smoke and milky oil on dipstick. If you replace the head gasket and the problem persists, an intake gasket could have fixed the problem.

My 04 jeep grand cherokee is smoking from the radiator. the radiator fan doesn't appear to be running. i've had to put more and more coolant in the resivior because it keeps going right through it...

well,probably needs radiator replaced,burning off fluid smoking problem?if not going out exhaust or in oil,have radiator checked-replaced,if fan not running check relay and fuses,might need fan replaced,if you overheat engine to bad you will blow head gaskets and this is costly.check your oil,see if gray and milky,if so blown head gasket and water-antifreeze in oil,if going out exhaust will be blown head gasket inbetween the cylinders,fix radiator and fan first,but check out to see where all fluid is going.

The car keep overheating, there is water in the radiator and the resevior tank 2000 jeep grand cherokee i check the oil their is no water found in the oil the water from both unit stays full

Sounds like your thermostat is stuck closed. Shouldn't be more than a $20 part from autozone and is simple to replace. Follow your top radiator hose to the motor and it will connect to your thermostat housing. Disconnect the hose (antifreeze will run out) unbolt the housing, and replace the old thermostat. Refill radiator and bleed the system.

Just had the oil changed in Jeep Cherokee and antifreeze is leaking into the oil. What could cause this?

Hi and thank you for using fixya:
This problem is caused by having a bad head gasket water will leak into your cylinders eventually passing on to the carter where the oil is kept. I suggest you change this as soon as possible as your car can malfunction .
Good luck

I have a 1995 Grand Cherokee out a new thermstat

If the engine is getting hot enough it sounds like the flow through the heater core is restricted. When it is hot turn the heater on and feel the radiator hoses. One should be real hot and the other a little cooler, not much. Try taking the heater hoses off and run water from a garden hose through them. Run both directions and maybe it will break something loose. You won't lose much antifreeze by unhooking the heater hoses.

1994 jeep grand cherokee, over heats and dont get more than 3000 rpms, what you think?

I think you need to service the cooling system on this 15 year old car. But first, turn on the A/C and the cooling fan should run continuously. If not, the fan motor is bad, the fuse is blown, or the relay is defective. Also if the fan runs with the A/C on but does not run when it is not on even when the engine overheats, the thermal relay is bad. Check the water pump closely for leaks. If you see a leak at the pump it is bad and must be replaced. If you see white smoke from the exhaust or a white foam on the underside of the oil fill cap, and are loosing coolant with no apparent leak, you may have a blown head gasket. If so, have it looked at by a professional for diagnosis. If you do not think you have a blown gasket then proceed. Inspect all hoses and replace as necessary. Purchase 1 gallon of antifreeze and 1 gallon of distilled water or 2 gallons of premixed coolant. Also purchase a new thermostat. Set the heater to hot, drain the coolant, flush the system, and replace the thermostat. Pour in a 50/50 mix of antifreeze and distilled water. Leave the radiator cap off and start the engine. Keep the radiator topped off and you watch for air bubbles escaping from the radiator. When you see no air bubbles escaping replace the cap and check for leaks.

Where do one out water for the coling system and

Two systems used on Jeeps...On those with a radiator cap, add to radiator then top off recovery bottle. On those with no cap, there is a tank with a screw on cap usually on the right fender. Add coolant there. Use antifreeze, not water or inside of engine will rust. Keep mix at 50/50. Never open either system with engine hot. Best to fill either system with engine running and heater on hot.
