Oil Cooler Line

Automatic transmission oil cooler pipes must be replaced by double-wrapped and brazed steel pipe following gm specification 123m or equivalent to produce double-flared pipes. A vehicle lift helps to steadily position the vehicle for pipe work while you should place a catch pan under it. The procedure for replacing automatic transmission oil cooler pipes starts by removing transaxle oil cooler hoses then moving on to disassemble the transaxle oil cooler pipe fittings at the radiator followed by the transaxle oil cooler pipe clip bolt until the transaxle oil cooler pipes can be removed from the system. The installation requires proper thread engagement to prevent leaks before you install the transaxle oil cooler pipes with the clip bolt secured to 4 nm (27 inch lbs.). Install the transaxle oil cooler pipe fittings to the radiator while torquing them to 45 nm (33 ft. Lbs.) before attaching the hoses to these fittings. The transaxle will operate better when the vehicle is lowered and the transmission tank is not filled beyond its recommended mark to prevent foam development and subsequent fluid loss along with shifting issues and component damage. Afterward check both the transmission fluid level as well as inspect whether all repairs were done correctly before searching for fluid leaks.

The automatic transmission oil cooler pipes must receive only double-wrapped and brazed steel pipe products that follow gm specification 123m or an equivalent standard with double-flare pipes. Start by raising the vehicle above the floor while supporting it and place a drain pan under it. First detach transaxle oil cooler hoses from the pipes before removing their fittings at the radiator and finally untightening the transaxle oil cooler pipe clip bolt. Detach the transaxle oil cooler pipes as the next step. Correct thread engagement at each step of installation protects against leaks that occur with cross-threaded connections. The transaxle oil cooler pipes require installation together with the transaxle oil cooler pipe clip bolt which needs to be tightened to 4 nm (27 inch lbs.). After attaching the transaxle oil cooler pipe fittings to the radiator use 45 nm (33 ft. Lbs.) torque followed by connecting the transaxle oil cooler hoses to the pipes. Set the vehicle at the proper height while monitoring the transmission fluid amount to prevent overfilling since excessive fluid leads to both foaming and shift complaints and hurts transaxle health. Finish your checks by evaluating the restoration work quality while conducting a search for fluid leakages.

Use only double-wrapped and brazed steel pipe that meets GM specification 123M or equivalent, ensuring the pipe is double-flared.
