Description
The Mishimoto MMHOSE-CIV-88HH is a purpose-built silicone heater hose engineered specifically for the 1988-1991 Honda Civic, replacing the factory rubber hose with a dual-layer silicone construction reinforced by heat-resistant embedded fibers. This isn’t a universal-fit hose cut to length in a shop; it’s a molded assembly designed from the ground up as a direct OEM replacement for this generation of Civic.
Mishimoto built this heater hose to handle the heat and pressure demands of an aging cooling system without the cracking and swelling common to old factory rubber. The dual-layer silicone and embedded fiber construction efficiently reduces heat and increases pressure tolerance compared to a worn-out original hose, while the molded shape restores a factory-correct routing under the hood. As part of Mishimoto’s Fabrication lineup, this hose is intended for enthusiasts and shops who want a reliable OEM-fit replacement backed by the Mishimoto name, rather than a generic aftermarket cut hose.
Vehicle Applications
This Mishimoto heater hose is a specific, not universal, fit and is designed for the 1988-1991 Honda Civic Base, DX, LX, and RT 4WD trims. It also fits the 1989-1991 Civic Si and the 1990-1991 Civic EX, as well as the 1988-1989 Civic Wagovan. Because it is molded for these exact applications, it drops in without modification on the covered years and trims listed above.
