Jeep Comanche

If a Jeep 88 turns over but won't crank, it could be due to several issues. Common causes include a weak battery, faulty starter motor, or ignition system problems, such as a bad ignition coil or spark plugs. Additionally, issues with fuel delivery, such as a clogged fuel filter or failing fuel pump, might prevent the engine from starting. It's important to systematically diagnose each component to pinpoint the exact problem.

To replace the heater core in a Jeep Comanche, start by draining the coolant and disconnecting the negative battery cable. Remove the dashboard and the heater assembly, which may involve taking out several screws and bolts. Once you have access to the heater core, disconnect the hoses and remove the core from the housing. Install the new heater core, reassemble the heater assembly and dashboard, and then refill the coolant before testing the system.

To add Freon to a 1989 Jeep Comanche, locate the low-pressure service port on the air conditioning system. This port is typically found on the larger diameter aluminum line, usually near the compressor. Remove the cap and attach the recharge hose from the Freon canister to the port, then follow the instructions on the canister to add the refrigerant properly. Always ensure the AC system is running and follow safety precautions.

On a 1989 Jeep Comanche, the crank position sensor is typically located on the engine block, near the flywheel or the rear of the engine. It's often mounted to the bell housing of the transmission, where it can read the position of the crankshaft. If you're having trouble locating it, refer to the vehicle's service manual for specific diagrams and instructions.

To change the clutch on a 1986 Jeep Comanche, first, safely lift and secure the vehicle. Remove the transmission by disconnecting the driveshaft, unbolting the transmission crossmember, and detaching the shifter and wiring harness. Once the transmission is out, take off the old clutch assembly (pressure plate and disc) and replace it with the new one, ensuring to align it properly. Finally, reassemble everything in reverse order, making sure all connections are secure before testing the vehicle.

In a 1990 Jeep Comanche, the OBD (On-Board Diagnostics) plug is typically located under the driver's side dashboard, near the steering column. It may be positioned above the brake pedal or close to the fuse panel. Since the 1990 model uses OBD-I, the connector might look different from later OBD-II connectors. Make sure to check for any cover or panel that may need to be removed to access it.

Loss of power in a 1998 Chrysler Sebring convertible could be caused by several factors, including a failing fuel pump, clogged fuel filter, or issues with the ignition system such as worn spark plugs or faulty ignition coils. Additionally, problems with the air intake system, such as a dirty air filter or malfunctioning mass airflow sensor, can also lead to reduced engine performance. It's advisable to perform a diagnostic check to pinpoint the exact issue.

To replace the radiator in a 1987 Jeep Comanche, first, drain the coolant by opening the petcock at the bottom of the radiator. Disconnect the hoses, electrical connectors, and any mounting bolts securing the radiator in place. Remove the old radiator and install the new one, ensuring it aligns properly with the mounts. Reconnect the hoses and electrical connections, then refill the cooling system with new coolant and check for leaks.

To install trailer wiring on an '88 Jeep Cherokee, first locate the vehicle's tail light harness. You'll typically need to splice into the rear light wires for the brake, turn signals, and running lights. Use a trailer wiring harness adapter if available for a simpler installation; otherwise, ensure proper connections and use heat shrink or electrical tape to protect the splices. Finally, test the connections by hooking up the trailer to ensure all lights function correctly.

In a 1988 Jeep Comanche, the fuse box is typically located under the dashboard on the driver's side. You may need to remove a cover to access it. The fuse box contains various fuses for different electrical systems, and a diagram on the cover or in the owner's manual can help identify which fuse corresponds to specific functions. Always ensure the vehicle is off before inspecting or replacing fuses.

The 2.5L engine in a Jeep Comanche can be interchanged with the 2.5L engine from other Jeep models, such as the Jeep Cherokee (XJ) from the same era. Additionally, the 2.5L engine used in the Jeep Wrangler (YJ) is also compatible. It's important to ensure that the engine's year and specifications match to facilitate a smooth interchange. Always verify compatibility with engine mounts and other components before proceeding with the swap.

In the 1987 Jeep Comanche, the fuel pump is located inside the fuel tank. To access it, you'll need to remove the tank from the vehicle, as it is not externally accessible. This model typically uses an electric fuel pump, which is mounted on the fuel sending unit within the tank. Always ensure proper safety measures when working with fuel systems.

No 1988 is OBD 1, the connecter is under the hood.

It could be the IAC module that sits next to the throttle body. It controls your idle and is non-adjustable.Try cleaning toyr throttle body system first, if tht doesn't work it will need to be replaced. Good luck, Mike

WINDOW MOTOR JEEP Cherokee, 84-86

starting price is 55.00 and buy it now is 80.00; at the time of purchase you let the seller know which window you need the motor for. I assume that means they have them in stock.

Becacuset there's something still drawing power. Hook an ampmeter to the battery, then pull the fuses one by one to see when the current drain stops. Then look at what's powered from that fuse to find the fault.

inside gas tank.

They both have the same job, the only thing difference is their application. The "shock" dampens continued vibrations from the springs while the "stabilizer" dampens the "shimmy" that the front tires cause.

None. The Comanche uses a spring under axle setup and blocking the axle would lower the vehicle. However, if you can use a torch and weld, you can cut your spring mounts, do some grinding and relocate them to the topside of the axle housing, and turn it into a spring over axle setup, giving you about 4.5in. of lift in the rear.

It takes about 14 hours to travel from BullHead City to Colorado Springs.
