Depending on the model year, the Jeep Cherokee has a few weak points where coolant leaks are apt to occur. The earlier models tend to have more problems with coolant leaks, but all Jeep Cherokees are susceptible to this issue.
The closed cooling system, which was used on the Jeep Cherokee between 1987 and 1991, relied on a pressure bottle rather than a conventional radiator with a cap. These plastic bottles are notorious for cracking and leaking coolant. On 1992 and later models of the Cherokee, Jeep replaced the problem-prone pressure bottle with a standard radiator.
The lower right and left corners of the radiator in models produced after 1992 are prone to debris build-up because of the radiator frame position. It is difficult to clean the radiator with a garden hose because of its location; consequently, failures in these areas are common.
The lower radiator hose, often neglected during routine service inspections and maintenance, is a common trouble point for coolant leaks. You should inspect the condition of this hose every couple of months and promptly replace when it looks worn or tiny cracks begin to appear.
If your Jeep Cherokee is consuming coolant but you cannot find a leak, it is possible the head gasket has blown. Check the oil and make sure there is no coolant in it. If there is, do not drive the car until the head gasket has been replaced.
