How to Remove the Lower Trans Cooler Line on a 1989 Jeep XJ

Removing the steel cooling lines from the radiator to the transmission on your 1989 Jeep Cherokee may be necessary if the line cracks or other damage is detected on the line or fitting. The line runs from the passengers side of the radiator on the Jeep to the passengers side of the transmission and carries transmission fluid from the transmission to the radiator for cooling before returning the fluid to the transmission. A defective or leaking line will cause fluid level drop in the transmission, damaging the internal components or parts.

Instructions

    1

    Raise the front of your Jeep with a jack and position a set of jack stands under the front axle to support it. Lower the jack, allowing the Jeep to settle onto the jack stands.

    2

    Slide under the passengers side of the Jeep and locate the cooling line at the radiator. Place an oil drip pan on the ground below the line at the transmission and at the radiator then use a wrench to turn the fitting on the line counterclockwise to loosen it.

    3

    Slide the fitting out of the radiator and down the line. Follow the line from the radiator to the transmission. Loosen the fitting where it enters the transmission with a wrench then pull the line out of the transmission.

    Slide the line back from the transmission and drop it out from under the Jeep. Slide it out from under the Jeep and discard it.
