    You have this a little bass ackwards...Your water heater is your engine (which technically is nothing more than a heat pump)....
    If you are overheating in traffic, either your electric fan is not coming on, the radiator is externally or internally obstructed, or you are low on coolant. Which of these problems do you have?

Change the Radiator Fan Relay. It's located under the Passenger side headlamp, below the plastic area the headlamp sits in. Remove headlamp then carefully drill out the plastic (on side closest to fender) with several holes to create an opening for your hand. Be careful not to allow the drill bit to break through and actually destroy the connection below. Just be careful and you will be fine. Anyone with a basic mechanical knowledge can do this. The relay is held in place by 2 8mm bolts and the part is about $60.
Good luck and you can do this in about 1hour or less.

My engine overheat when A/C is running on a slow moving traffic or on parking.


I would check and see how much air is actually moving thru the radiator. The fan may not be running fast enough or you may have debris blocking the air flow. Also make sure the system is full of coolant and no air pockets.

Check the fuse for the fan and use a test light to make sure that the circuit is functioning. Warm up your car then feel along the top and bottom of the radiator to check for cold spots. If you find any then you may need to replace your radiator. If your heater isn't currently working it may be that since it is a part of your cooling system.

While driving my cherokee jeep , heard a flapping sound from the engine. Car cut out. On investigation car had lost all its water. The car was able to re start.


Is the drivebelt still there? Look for leaks...where did the water go? After any overheat, I suggest you replace the thermostat. They aren't expensive but after an overheat they can become unreliable even if it did not cause the overheat and so should be changed.

2001 jeep grand cherokee has little or no heat from heater


I would recommend flushing your cooling system and especially your heater core.With water and compressed air. Possibly replacing your thermostat while your doing that too

Engine overheating


Try to flush the system And inspect radiator. When moving the engine is also cooled by air. Make sure the water is circulating trough the manifold and the heater core. You can do this by atching a garden hose to each hose one at a time. You may also want to check the waterpump & thernostat..

2001 Jeep Grand Cherokee Laredo Overheating


Three possible solutions:

1. Bad Thermostat

2. Fan Relay (most likely)

3. Bad Fan

When the GC reaches a temp of 180 Deg. F the fan relay sends a signal to the fan to turn on, once the temp lowers (around 155 Deg. F) the relay turns off the fan, and so the cycle continues. If the relay is bad there will be no signal to the fan to run. While you are driving your vehicle there is ambient air moving thru the radiator, cooling the engine, but once you encounter slow/heavy traffic or stop there is no air moving and the temp goes up, the fan will not kick in and the vehicle will overheat.

If the fan motor is not working the same will happen, but a more expensive fix, as the motor comes with the fan.

If the Thermostat is stuck in the open position, the water travels to fast in the engine and heat exchanging is not an efficient process, therefore the vehicle might overheat when stopped or in slow traffic.

2001 Jeep Cold RAdiator


Does your temp gauge read normal? if it does then the thremostat is ok,but sadly the water pump is going bad this is typical of jeeps at an idle the heater cools off because the water pump fins are worn enough to not circulate through the heater core and when you step on the gas the increased rpm move the water fast enough to circulate through the heater,it is possible that the heater core is plugged but I doubt it as a plugged heater core would not get hot either it would be cold or just luke warm all the time.
