1999 jeep grand cherokee laredo overheating and blew upper radiator hose. have already replaced thermostat, fan clutch. water pump is a year old.

  • Anonymous Nov 01, 2010

    Either the hose was in poor condition to begin with or you have a serious problem such as a blown cylinder head gasket...When that gasket fails combustion pressure can get into the cooling system and cause the hoses to explode.

Chanches are it is probably the fan. Anything over 15 miles an hour the fan is no longer needed. I would get a cheap hydrometer and make sure your antifreeze is still good.

2001 jeep grand cherokee laredo overheating. replaced fan relay and thermostat, and its still overheating

suggest that you rent a pressure tester from auto zone or advance auto and preform a pressure test on your cooling system. follow the instructions on the test of pressure to your cooling system,also check for coolant leaks onto the ground from radiator area. may be bad water pump,broken hose,heater hose,upper radiator,lower radiator,or a bad radiator itself. a simple pressure tester will reveal the coolant leak. but make sure to follow the instructions with the pressure tester,as you can damage your coolant system otherwise. thank you for choosing fixya.com

Clutch Fan are known to fail over time, but I wold not rule out the radiator. The small passages inside the radiator will clog due to age. You did not mention how many miles are on the Jeep or if the Aux fan is kicking on.

2003 Grand Cherokee Overheating

This might help you as it looks as though you have an electric fan to cool , there should be a sensor on your radiator hoses upper and lower.they are actually switches triggered by the coolant temperature in side the hose. While your Jeep is sitting idle, shut off the AC as it adds to the heat off the engine not to merntion useing more gas. you should make sure both high and low speeds on the coolant fan work. good luck if this does'nt help check out the post, with more, on the 1995 Jeep heating up..
