Gates 11-13 Toyota Highlander V-6 3.5L Electric Assist Aux. Rad. Inlet Molded Coolant Hose

This molded coolant hose from Gates is specifically shaped to connect the electric assist auxiliary radiator on your 2011-2013 Toyota Highlander with the V-6 3.5L engine. It's built to handle the specific routing and pressure requirements of that particular cooling system setup. Because it's a molded hose, it follows the factory bends precisely, making installation straightforward without needing to fight a stiff, straight hose into place.

Gates uses a strong, heat-resistant rubber compound for the inner tube and cover, ensuring it can withstand the high temperatures and constant flow of coolant found in your engine bay. The reinforcement layers within the hose construction add to its durability and help prevent it from collapsing under vacuum or expanding under pressure. This means you get a reliable connection that's less likely to leak or fail prematurely compared to a generic hose.

Replacing a coolant hose like this is a good idea if you notice any cracks, swelling, or leaks, especially if the original hose is showing its age. It's a critical part of keeping your engine running at the right temperature, and a failure can lead to overheating.
