Two problems related to coolant leaking have been reported for the 2001 Jeep Laredo. The most recently reported issues are listed below.
For the past year my 2001 Jeep grand cherokee Laredo limited has been overheating if we idle for more than 1-2 minutes. As long as the rpms don't go over 2000 it will happen. I went on a trip last may up a canyon. Drove about 50 miles to the canyon and all was fine. While going up the canyon speeds stayed below 20 mph because we were following my in-laws and there was quite a bit of dust the ac was off I didn't notice that the temperature gage was raising. When I noticed it, I guess it was too late. I stopped the Jeep and hoped that it would cool down. As I lifted the hood. The top popped of the coolant reservoir and sprayed coolant everywhere. I was able to get home without any problem because I was going fast again. I put more coolant in it and it still overheats at drive-thru's and in rush hour traffic. I have to turn it off. In fact when I got it registered they left the Jeep running and the cooling system reservoir top popped off then. They told me to be careful and add coolant ASAP. I thought it was just me, but looking and all the other problems I realize that this is serious. The electrical is also shoddy. I thinks it's because the coolant has leaked all over the wires. My main complaint is the cooling though. You shouldn't have to worry about your car overheating in slow//stopped traffic.
2001 Jeep grand cherokee. Leaking coolant. Replaced water pump and hoses. Continued to leak, oil pressure drops at idle and recently coolant has been found mixed with the oil. The head is cracked and allowing coolant to mix with the oil. Seems to be a common problem in Jeep heads cast around 2000.
