Mishimoto Coolant Hoses

Mishimoto’s coolant hoses are vehicle-specific silicone kits rather than hose sold by length. The largest group is radiator hose kits, the hoses between engine and radiator. Other kits are listed as silicone hose kits or ancillary coolant hose kits, which take in more of the system’s smaller hoses, and a few cover the air intake or induction side. Each kit is moulded to follow the original routing, with the bends and any change of diameter built in, so it fits without cutting.

The choice within a kit is mostly colour: black, blue or red, with a matte black finish on some. Where one car has more than one kit, compare the titles: a radiator hose kit and a full hose kit replace different numbers of the original hoses. Replacement kits are also listed for some models.

Silicone is softer on its outer surface than rubber hose, so use smooth-band clamps or the clamps supplied, tighten them evenly, and re-tighten after the first few heat cycles. Refill with the coolant the car maker specifies and bleed the system until no air remains.
