Heater Hose H-Pipe Crossover Fitting

Heater Hose Bypass Fitting – Coyote Engine Cooling Solution

This heater hose bypass fitting is a simple but critical upgrade to keep your engine running cooler and more reliable. By maintaining constant coolant flow, it helps prevent overheating and avoids costly engine damage. While it benefits all vehicle types, this fitting is especially important on Ford Coyote engines where coolant flow can become restricted without it.

Why Add an H-Pipe Bypass

Ford Motorsports recommends a heater control valve bypass to keep coolant circulating through the right-hand cylinder bank on Coyote engines. Without this bypass, shutting off the heater can deadhead coolant into the heater core, starving the passenger-side head of circulation. This condition can trigger overheating and limp mode. Installing this H-pipe ensures coolant continues to recirculate properly, protecting your engine even when the heater is off.
