The Toyota 2GR 3.5L V6 has earned its reputation for reliability, but one known weak point continues to cause issues over time: the factory rear water crossover pipe (part number: 16356-31051 > 16356-31050).
From the factory, this pipe is made from plastic and mounted directly to the rear of the engine. With repeated heat cycles, the plastic and aluminum expand and contract at different rates. Over time, this mismatch can lead to cracking at the sealing surfaces, resulting in coolant seepage or failure. The problem doesn’t end there. Replacing the factory pipe with another OEM unit means reinstalling the same plastic design, leaving the door open for the same failure down the road. Some workarounds involve adapting parts from other models with additional hoses and fittings, adding complexity and more potential leak points. Considering the labor involved in accessing and replacing this component, it’s not a job you want to do twice.
TEQSPORT’s solution is a direct-fit aluminum rear coolant bypass pipe designed to eliminate these concerns entirely. Built to install in the factory location with no modification to hoses or engine components, it delivers a permanent upgrade in both durability and reliability.
Constructed from cast aluminum with critical features precision-machined for accuracy, this pipe expands and contracts in line with the engine, reducing stress at the sealing surfaces. Paired with OEM-style gaskets, it delivers a consistent, reliable seal built for long-term durability.
This is a one-and-done solution designed to match the lifespan of the engine it’s bolted to.
