Question about 1989 Jeep Cherokee
Managed to fix mine by replacing the bottle and cap and installing a bypass filler/burper , cut the hose in half and install with a few clamps then fill radiator from there,best of all you can just connect the water hose to it to fill when draining and refilling.(it comes with directions)i put mine in the hose that comes off the goose neck(thermostat)to heater core.this way u dont get air/steam pockets which can cuase over heating.too

Several things cause Cherokees to overheat...the biggest problem lies with the overall design of the coolant system itself, namely adding fluids to a reservoir rather than directly to the radiator. I've had this problem on-going for most of this year and have replaced everything so far.
Leaks began from a faulty lid on the reservoir which eventually led to it blowing off while driving. Found a used reservoir at wrecker for 5 bucks without lid, then had to purchase a lid from the dealer for 13. It also shows up black oil, which shows high running temps..which was not indicated by the temp. sensor (unplugged it). Over the summer, had several problems with running at high temps including having the car not start at all. In conclusion...the rad was plugged causing the coolant to not ciruculate and finally blew a hole through the front of it. ...replacing it tomorrow. The high heat temp of the car was also causing the Crankshaft Sensor to fail... solved this by resetting the computer.
With the key on but vehicle not running, disconnect the negative battery cable for about a minute. This should reset the computer until you can get it serviced or moved to a repair shop. Mine ran fine as long as I didn't go far, or run it for more than 30 minute trips...which is good since I'm in a small town. Now that the weather has gotten cooler..no more problems with it not starting...but the rad will be changed tomorrow. Have also already changed the water pump & thermostat, but the latter will likely have to be replaced since it's been running hot all year.
