[quote:b7dbf7dfd7="VitezJZ"]I have 2000 Jeep Grand Cheeroke Laredo with 106000 miles on it, and whenever i turn on A/C my engine overheats. Does anyone know what could be wrong with this? :?:[/quote:b7dbf7dfd7]
Well, does your truck have a fan attached to the engine, or electrical fans mounted to the radiator? The reason it gets hotter with the AC on is it adds a load to the engine, and the condesor is used for cooling, which robs some of the air for the radiator. Usually if you have electric fans, they are commanded on when the A/C is on. If you have the fan attached to the front of the engine, it should lock up the clutch when the increased temp is sensed and turn faster. If this is not happening, you may need to replace the clutch for your fan.
