Description
The Mishimoto Silicone Heater Hose Kit (MMHOSE-4RUN34-96HHRBL) is a direct-fit, blue silicone replacement designed explicitly for the 1996-2002 Toyota 4Runner 3.4L equipped with the factory rear heater system. After two decades of service, the factory rubber heater hoses on these third-generation 4Runners are prone to cracking and wear, and this Mishimoto Fabrication kit replaces the entire heater hose circuit with durable, heat-tolerant silicone.
Built from 4-ply silicone with heat-resistant embedded fibers, this performance-grade heater hose kit is engineered for superior heat and pressure tolerance, carrying a maximum temperature rating of 330°F. The kit is a specific-fit application rather than a universal hose, so it installs using the factory routing while upgrading material quality over the aging stock rubber. It’s offered in blue to add a distinct accent under the hood, and every kit ships complete with the stainless steel worm-gear clamps needed for a clean installation, backed by Mishimoto’s Lifetime Warranty.
Vehicle Applications
This heater hose kit is a specific fit for the Toyota 4Runner V6 3.4L, covering the 4Runner Limited and 4Runner SR5 trims from 1996 through 2002, as well as the 4Runner Base trim for the 2001 model year. It is intended only for 4Runners equipped with the factory rear heater system, so confirm your truck has this setup before ordering.
