Installation Notes and Tips

• Verify the routing before installation: auxiliary cooler (passenger side) to transmission, or lower transmission-to-radiator line.
• Confirm the vehicle is a 1997-2001 Jeep Cherokee and check whether it has an auxiliary oil cooler.
• Inspect the mating quick disconnect fittings and surrounding cooler lines for wear or contamination before assembly.
• Match the hose length and routing to the original line to avoid strain on the connections.
