Engine Cooling problem
2000 Jeep Cherokee 6 cyl Four Wheel Drive Automatic

Six months ago I replaced the water pump. I recently replaced the radiator because of a leak. Both radiator hoses are new. The car was pulled into the driveway and idling and the hose blew off of the connection at the engine. I thought it may have been a bad thermostat or radiator cap and replaced both of them. I refilled with antifreeze and started the car back up and within ten minutes the hose blew off again. There is no water in the oil or steam coming from the exhaust. What is going on?

Could be that the metal pipe that the hose is going onto is out of shape or damaged by corrosion, your hose clamp might be at fault or could have a serious blockage in radiator / cooling system.

Is the vehicle over heating when this happens? If not maybe the clamps are not tight enought. You might want to install worm style clamps if not already done.

I have installed the worm type hose clamps and the fitting the hose goes on is in like new condition. The hose did not blow off this time but there was so much pressure built up it was blowing out of the radiator cap like it is supposed to. The hose was swollen up and ready to burst. It did get to an overheat situation and I shut the engine down. Any other suggestions? Like I said previously, no water in the oil and no steam out of the exhaust. What can it be?

The system is not clogged. Radiator is brand new and I flushed out the engine block and heater core when everything was replaced. Replaced water pump, radiator, thermostat, radiator cap, upper and lower hose, and currently using 2 to 1 ratio coolant and water.
