Product Reviews
Vehicle Fit

This rear engine oil cooler line assembly is among the highest quality replacements on the market. It's just what you need to get your vehicle in good working order again!


  • Replaces the REAR section of a 2 part hose set
  • Mounts between the rear hose adapter and the oil filter adapter assy
    • The rear hose adapter attaches to the engine block where your oil filter would normally attach
    • The Oil filter adapter is where your present oil filter attaches
  • Replaces dealer part number: 15982251
  • Includes all materials needed to complete the repair (o-rings and gaskets where applicable) of the rear section of hoses
  • Redesigned to have more resiliency against "compression set" which can result in crimp failure. This is the number one failure associated with engine oil cooler line assemblies
  • Fits models that have 4WD (Four Wheel Drive) and use a V6 4.3L Engine only

Replace your rusted, rotted, or damaged rear oil cooler lines with this great fitting alternative. These rear engine oil coolant lines make a great replacement and have good cost savings over rear engine oil cooler lines from the dealer.
