    Q:
    How to replace the Transmission Oil Cooler Hose on Cadillac Escalade? Posted by Customer
    A:
    Start the replacement process of transmission fluid cooler hose/pipe by removing the front bumper fascia. The removal of the front upper fascia support fasteners allows you to tip the bracket backward. First remove the transmission fluid cooler hose from its connection to auxiliary Oil Cooler and Radiator. First raise the vehicle then carefully take out the engine protection shield. The first step involves disconnecting both cooling lines which are connected to the transmission. You must remove the right differential carrier mounting nuts together with washers but always avoid using air-powered tools for these crucial bolt torques. First detach the bolt that secures the right front shock rear mounting to the lower Control Arm then remove all oil cooling lines present on the vehicle. Install the transmission Oil Cooler lines by bypassing the use of air-powered tools. The right shock rear mounting bolt gets installed onto the lower Control Arm while tightening it to 50nm (37 lb ft) torque strength. Afterward, the right differential carrier mounting nuts and washers need 100nm (75 lb ft) torque for tightening. Proceed with attaching the transmission to its cooling lines and reinstall the engine protection shield before lowering the vehicle. Reinstall the front upper fascia support bracket together with the front bumper fascia after you have connected the transmission fluid cooler hose to both Radiator and auxiliary Oil Cooler.

    How to replace the Transmission Oil Cooler Hose on Chevrolet Tahoe? Posted by Customer
    A:
    The first step to replace a transmission fluid cooler hose/pipe involves the removal of front bumper fascia. The bracket requires tipping back by first removing the fasteners from the front upper fascia support. Cut the transmission fluid cooler hose from connecting points which are established between the auxiliary Oil Cooler and the Radiator. Begin by first lifting the vehicle then remove the engine protection shield. The first step is to detach cooling lines from the transmission and thereafter extract right differential carrier mounting nuts and washers while avoiding air-powered tool usage because accurate bolt torques are necessary for proper diagnosis. Start by removing the lower Control Arm shock rear mounting bolt from the right front side while draining the vehicle of its oil cooling lines. The first installation step requires fitting the transmission Oil Cooler lines but it is essential to use manual tools to prevent addition of air. To finish installation the mechanic must bolt the right shock rear mounting bolt to the lower Control Arm at 50nm (37 lb ft) and tighten the right differential carrier mounting nuts and washers to 100nm (75 lb ft). The cooling lines must be connected to the transmission as you install the engine protection shield and lower your vehicle to finally join the transmission fluid cooler hose between both Radiator and auxiliary Oil Cooler. The completion of the repair requires reinstalling the front upper fascia support bracket while reinstalling the front bumper fascia as well.
