• Q: How to Properly Handle Transmission Oil Cooler Hose Replacement on 2009 Chevrolet Impala?

  A: A replacement of the transmission fluid cooler hose/pipe requires disconnecting the transaxle oil cooler (TOC) outlet hose that runs from the top side of the Radiator. After properly raising the vehicle place it on supports and remove the toc hose retainer bolt while setting a drain pan under the oil cooler hoses. Disconnect all transmission fluid cooler hoses starting from the transaxle whereas the outlet hose comes off first then proceed to the inlet hoses on the Radiator before removing all components from the vehicle. The installation process requires that enough space exists around transaxle oil cooler pipes and hoses to prevent difficulties with wear or damage. Before reinstalling the toc hoses onto the vehicle they must be attached to the Radiator support retainer at the top followed by the Radiator and finally the transaxle. Install the toc hose retainer and bolt with 25 nm (18 lb ft) torque setting then lower the vehicle before applying the toc outlet hose to the Radiator top side. Taking care to avoid excessive fluid quantity will prevent damaging foam formation and the subsequent loss of fluid and transmission shift complaints while protecting device components. Conclude the procedure by following guidelines for transmission fluid level adjustment that combine proper fluid checks and recommended fluids as well as approximate capacity figures.
