Q: What tools are required to replace the Transmission Oil Cooler Hose on Buick LeSabre?
A: The cooler quick connect tool (J 41623-B) stands as a necessary tool for changing transmission fluid cooler hose/pipe. First lift the vehicle before finding an appropriate resting point while having a drain pan in place. First disconnect the retainer holding the transaxle oil cooler hose at the transaxle before moving away the white plastic covers from the quick connections. Detach the transaxle oil cooler hoses from the transaxle and the Radiator through the use of the cooler quick connect tool (J 41623-B) so you can take the hoses off the vehicle. The installation of new transaxle oil cooler hoses will proceed by inserting the pipes through the car until the fittings on the Radiator quick connect activate. Visualize correct retention of hoses by applying mild force to the hose ends. After that, install the white plastic covers over the quick connections. Push the hoses until a click sound occurs when they reach the transaxle quick connect fittings then gently pull the hoses to verify retention. Check the fluid level after setting the transaxle oil cooler hose retainer to the transaxle device and lower the car then inspect both the fluid amount and signs of leakage.
