This part is listed for 2005-2017 Toyota Tacoma applications and 2010 Toyota 4Runner applications, with plastic construction noted in the fitment data. When the original bypass pipe becomes brittle, cracked, or begins to leak, replacing it helps restore the coolant path used by the engine cooling system. The SK121408 part number is useful when matching the correct replacement during cooling system repair.\u003c\/p\u003e\u003ch2\u003eCommon Issues This Part May Solve\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCoolant leaks from a cracked bypass pipe\u003c\/li\u003e\n\u003cli\u003eLoss of coolant from aging plastic cooling components\u003c\/li\u003e\n\u003cli\u003eCooling system service after pipe deterioration\u003c\/li\u003e\n\u003cli\u003eIncorrect replacement selection during Toyota cooling repairs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the vehicle year, model, and cooling system configuration before ordering.
