Product Details

When your Toyota Highlander's cabin isn't getting warm, or you're seeing coolant leaks around the engine, a worn heater hose could be the culprit. This molded heater hose from Gates is specifically designed to connect your throttle body to the thermostat housing on the 2001-2003 Highlander with the 4-cylinder, 2.4L engine. It's a direct replacement for the original part, ensuring a proper fit and reliable coolant circulation.

Gates uses a heat-resistant rubber compound for this hose, built to withstand the constant temperature fluctuations and pressure found in your cooling system. The molded shape means it follows the factory routing precisely, making installation straightforward without needing to bend or force the hose into place. This helps prevent kinks or stress points that could lead to premature failure.

Replacing a heater hose is a common maintenance task, especially as vehicles age. Having the correct, well-made hose like this Gates part makes the job much easier and helps ensure your heating system works correctly for seasons to come.
