Description
The Mishimoto MMHOSE-WR6-91BK is a black silicone radiator hose kit engineered specifically for the 1991-1995 Jeep Wrangler YJ I6, replacing the factory rubber upper and lower radiator hoses with a five-layer silicone construction built to resist the cracking and degradation that plague aging rubber. This direct-fit kit ships complete with four worm-gear clamps, making it a straightforward, bolt-in cooling system upgrade for YJ owners who want a more durable hose without hunting down separate hardware.
Where rubber hoses harden and crack over time, Mishimoto’s silicone hoses are built from five layers of silicone reinforced with heat-resistant embedded fibers, giving them a Maximum Temperature Rating of 330°F and improved resistance to both heat and pressure cycling. That added durability matters whether the Jeep is crawling over rocks, working a trail, or just handling daily driving duty, since the cooling system hoses see constant heat exposure and vibration. As a Cooling system component from Mishimoto, this hose kit is offered as a Performance-grade, vehicle-specific product rather than a generic universal hose, and it’s also available in blue or red for owners who want to color-match their engine bay.
Vehicle Applications
This hose kit is built specifically for the Jeep Wrangler YJ I6 and covers several trims across the model’s run. It fits the Jeep Wrangler Base from 1991 to 1993 and the Wrangler Islander from 1991 to 1992, as well as the Wrangler Renegade from 1991 to 1994. Coverage extends through the Wrangler Sahara for the full 1991 to 1995 span, and the Wrangler SE is covered for 1994 and 1995. If your YJ falls within these trim and year combinations, this kit is a direct replacement for the factory upper and lower radiator hoses.
