The 1998 jeep grand cherokee 5.9 Limited has several known issues.

Engine Issues

The engine is the heart of any vehicle, and the 1998 jeep grand cherokee 5. 9 limited is no exception. However, like any machine, it can encounter problems over time. In this section, we will discuss the most common engine issues faced by this particular model.


Overheating is a widespread problem with the 1998 jeep grand cherokee 5. 9 limited. This issue can lead to serious engine damage if not addressed promptly. Some factors that contribute to overheating include:

Coolant leak: A leak in the coolant system can cause a loss of coolant, leading to inadequate cooling and eventual overheating. Regularly inspect the coolant reservoir for any signs of leaks.

Faulty radiator fan: The radiator fan plays a crucial role in maintaining optimal engine temperature. If the fan fails to operate correctly, it can result in overheating. Keep an eye on the fan’s performance and have it checked if necessary.

Blocked radiator: A clogged or blocked radiator can restrict the flow of coolant, resulting in overheating. Ensure the radiator is free from debris or contaminants that may hinder its efficiency.

Oil Leaks

Another common engine issue faced by the 1998 jeep grand cherokee 5. 9 Limited is oil leaks. These leaks can occur in various parts of the engine, including:

Valve cover gaskets: Over time, the valve cover gaskets can become brittle and wear out, leading to oil leaks. Inspect the valve covers for any signs of leakage and replace the gaskets if necessary.

Oil pan gasket: The oil pan gasket can develop leaks due to age, corrosion, or improper installation. Regularly check the oil pan for any oil accumulation or dripping.

Front and rear main seals: The front and rear main seals are responsible for preventing oil leaks at the front and back of the engine. If these seals deteriorate, they can cause oil to escape. Keep an eye out for oil stains on the ground beneath the engine.


Misfires can occur when the engine cylinders fail to ignite the air-fuel mixture properly. This can lead to a variety of issues, including reduced engine performance and fuel efficiency. Here are some common causes of misfires in the 1998 jeep grand cherokee 5.

Faulty spark plugs: Worn or damaged spark plugs can result in misfires. Regularly inspect the spark plugs and replace them as needed.

Ignition coil failure: If the ignition coil fails, it can disrupt the spark generation, leading to misfires. Have the ignition coil tested and replaced if necessary.

Fuel delivery issues: Problems with fuel injectors or a clogged fuel filter can affect the proper delivery of fuel to the engine, potentially causing misfires. Ensure scheduled maintenance is performed to keep the fuel system in good condition.

Engine issues can be a headache for any vehicle owner, but understanding the common problems faced by the 1998 jeep grand cherokee 5. 9 Limited can help in proactive maintenance and timely repairs. Regular inspections and addressing issues promptly can minimize the impact of these engine problems and ensure the smooth operation of your vehicle.

Power Window Failure:

Power window failure is a common electrical problem experienced by jeep grand cherokee 5.9 limited owners. Some possible causes for this issue include:

Faulty window motors: Over time, the window motors may wear out, resulting in power window failure. Replacing the faulty motor can resolve the issue.

Wire harness damage: Damaged wiring harnesses can interfere with the proper functioning of the power window system. Inspecting the wiring and repairing any damage can help restore functionality.

Instrument Cluster Malfunction:

An instrument cluster malfunction can occur in a 1998 jeep grand cherokee 5.9 limited, leading to inaccurate or non-functional readings on the cluster. Here are some potential causes for this problem:

Faulty instrument cluster circuit board: Issues with the circuit board can disrupt communication between the various instruments. Replacing the faulty circuit board can resolve the malfunction.

Loose or corroded connections: Loose or corroded connections between the instrument cluster and the vehicle’s wiring can cause a malfunction. Inspecting and tightening the connections can help rectify the issue.

Battery Drain Issues:

Battery drain issues can be frustrating and leave you stranded. Here are some reasons why a 1998 jeep grand cherokee 5.9 Limited may experience battery drain:

Parasitic drain: Certain electrical components or accessories may draw power even when the vehicle is turned off. Identifying and rectifying the source of the parasitic drain can help preserve battery life.

Faulty alternator: If the alternator is not charging the battery properly, it may result in battery drain. Testing and replacing the faulty alternator can resolve the issue.

Weak battery: Over time, the battery’s capacity may decrease, causing it to drain more quickly. Replacing the weak battery can restore proper functionality.

By being aware of these electrical problems with the 1998 jeep grand cherokee 5. 9 limited, you can take proactive measures to address and resolve any issues that may arise.

Transmission Troubles

The 1998 jeep grand cherokee 5. 9 Limited is known for its powerful engine and off-road capabilities. However, like any vehicle, it is not without its share of problems. One area where owners often experience issues is with the transmission.

From shifting problems to torque converter failure, here are some common transmission troubles you may encounter with this model:

Shifting Problems

Rough shifting: You may notice a jolt or hesitation when shifting gears, particularly when accelerating or decelerating.

Failure to shift: The transmission may get stuck in a certain gear and refuse to shift, causing a lack of power or acceleration.

Delayed engagement: When you shift from park to drive or reverse, there may be a delay before the transmission engages, leaving you momentarily stranded.

Torque Converter Failure

Overheating: One of the main causes of torque converter failure in the 1998 jeep grand cherokee 5.9 Limited is overheating. This can be due to a lack of proper fluid flow or an issue with the cooling system.

Slippage: A failing torque converter may result in slipping gears, leading to a decrease in power and difficulty maintaining speed.

Shuddering: If you experience a vibration or shuddering sensation while driving, it could indicate a problem with the torque converter.

Transmission Fluid Leaks

Transmission pan gasket: The gasket that seals the transmission pan can become worn or damaged over time, leading to fluid leaks. This can result in low fluid levels and potential damage to the transmission.

Torque converter seal: If the seal around the torque converter is compromised, it can cause transmission fluid to leak, resulting in inadequate lubrication and potential transmission failure.

Input and output shaft seals: The seals that prevent fluid from leaking around the input and output shafts can wear out, leading to transmission fluid leaks.

Remember, regular maintenance and proper care can help prevent and mitigate these transmission troubles. It’s crucial to check and replace transmission fluid as recommended by the manufacturer and address any issues promptly to avoid more significant and costlier problems down the road.
