Gates 02-11 Freightliner Columbia 6-Cyl. 14.0L Diesel Oil Cooler To Heater Coolant Tubes

If you're working on the cooling system of your 2002-2011 Freightliner Columbia with a 6-cylinder 14.0L diesel engine, you might need to replace the coolant tubes that run from the oil cooler to the heater. These Gates coolant tubes are designed to connect those two components, ensuring proper coolant flow for both your engine's oil temperature regulation and your cabin's heating system.

Gates uses durable materials in their coolant tubes to withstand the heat and pressure found in these heavy-duty diesel applications. This particular set is made to fit specifically between the oil cooler and the heater core, making it a direct replacement part for the original equipment. Having the right connections is key to preventing leaks and maintaining the integrity of your cooling system, especially on a large diesel engine where system failures can be costly.

When you're replacing these tubes, it's a good idea to inspect the surrounding hoses and connections for any signs of wear or damage. Having the correct, well-made replacement parts like these Gates tubes will help ensure your repair is done right the first time.
