The OE plastic connector is a frequent failure point due to brittleness and cracking caused by repeated thermal cycling and hydrolysis. Hydrolysis, the breakdown of plastic or rubber by water exposure, weakens the structure over time, leading to failure. To combat these issues, Rein’s upgraded connectors are constructed from high-strength aluminum, eliminating the vulnerabilities of plastic connectors and ensuring long-term durability.

Due to fragile plastic construction and consistent exposure to hot, chemical-rich engine coolant, this piece is prone to degradation and (potentially) complete failure.

Whether you're fixing a failed connector or preemptively replacing this failure-prone component, choose this quality replacement from Bremmen Parts for a lasting repair.
