I had the same symptoms and this was what I had going. But I think other things could cause the same trouble. Like a plugged radiator. But for me.....

I had the same problem after I replaced a water pump. Turns out the new water pump went faulty with in one month. It made no sounds and had no leaks. Plastic impeller broke off shaft and it would not pump water. The over flow would start to fill up almost immediately and the upper hose would get really hard. I removed the thermostat to rule out a bad thermostat and while it was removed I turned the motor over with out the upper hose attached. I found no water was being pumped. My solution was a new water pump. Not the cheapest one either. What a head ache my car was out of commission for 2 months. Good luck

How long as the radiator cap been on the car? If it is from the factory, replace it with a new cap and see if that helps.

Good Luck

Cooling system


Raise the car front end as high as possible with a floor jack, fill the coolant tank to the top, run the engine until it reaches just short of overheating, shut it down and run water over the radiator, this will burp the air out. Repeat as needed. Don't let the coolant recovery tank run dry during procedure.

1999Jeep cherokee leaking gasoline from top of the tank


From what I can uderstand, the leak is coming from where the filller neck attaches to the tank. If this is the case there should be a clamp that should be tightened. This should turn off the engine light. If engine light is still on check for a leak in the cap.
Other wise do not over fill the tank for fire issues.

I live in central ny Very cold here. My 99 Cherokee over heated guage warning came on and the cooled back down and overheated again. Resivoir was empty, I filled it and drove 40 miles and it was empty...


hi ,trust me you have a leak somewhere ,first fill the radiator/resiviour with water while your engine is running ,when its full and no more air bubbles are coming out ,put the cap on . now keep the jeep running for at least 30 minutes and every 5 minutes check underneath the engine for escaping water .you should spot the leak this way ,if not ,then your head gasket in your engine is probably leaking water into your exhaust and evaporating your water away without being seen ,this would require a large repair by a mechanic.

I have a 1997 Jeep Grand Cherokee Laredo that the top hose that leads from the radiator to the thermostat blew the other day. I replaced the hose with no problems but the gauge in the jeep keeps indicating...


The sensor would not likely have shorted, but the sensing material may have changed due to overheating. The thermostat may also be in trouble. Replace both, then take the car to Autozone or similar business for a free computer scan, which can remove any error codes. Then drive the car to see if it resets further codes. Make sure the cooling system is topped up in both the radiator and the overflow tank. Check your other hoses for condition and replace if necessary. If the entire engine overheated, be on the lookout for antifreeze leaks around the heads and for strange misfire codes. It may have warped the heads from excess heat. Hope this helps!

Where can i get an evap chart for 1999 jeep grand cherokee


Check under the hood for the complete chart of the vaccum routing of the EVAP.
The weak spot in the Jeep is the solonid valve and the EVAP cansiter.
If you fail the emission because of EVAP then look for the the gas fill neak for leak.
There are many potential leaky spot.
The key is DO NOT TOP OFF the gas when refilling. They excess fuel can damage the valve and canister.

Coolant low light came on?


you have a overflow container that ties into your radiator it should be white plastic with black cap check the level and fill with straight antifreeze up to the fill line not the top but if it is already full and you have low coolant in the radiator then you most likely have a bad water pump this is if the light is acurate and not malfunctioning

You need to instal an over flow container which you can get at the local parts store.. this way it catches any over flow and when engine cools down it will **** it back into the radiator... thanks Jerry
