Throttle Body to Lower Intake Bypass Hose | 1985-1988 22RE

Throttle Body to Lower Intake Manifold

Ensure your classic 22RE engine maintains proper thermal regulation and a steady idle with this premium Throttle Body to Lower Intake Bypass Hose. This specialized coolant bypass hose routes vital engine coolant directly between the throttle body assembly and the lower intake manifold. Over decades of exposure to extreme under-hood temperatures and high-pressure cooling-cycles, the original factory rubber degrades, causing it to harden, swell, or split-potentially leading to catastrophic coolant loss and engine overheating.

This replacement hose is precision-molded to match the original equipment (OEM) contours perfectly, navigating the tight spaces under the intake plenum without kinking, pinching, or rubbing. Constructed from an advanced heat-and chemical-resistant EPDM rubber compound, it is engineered to withstand modern cooling system pressures and additive-rich coolants, restoring long-term reliability to your 22RE's plumbing.
