These Mishimoto silicone heater hoses handle the coolant running to and from your heater core, and like the rest of the cooling system on a 30-year-old EF, the factory rubber is well past its best. Replace them with silicone rated to 330°F and stop a leak before it starts.\u003c\/p\u003e\n\n\u003ch4\u003eThe Hose People Forget\u003c\/h4\u003e\n\n\u003cp\u003eWorth calling out, because the heater hoses are easy to overlook until they fail.\u003c\/p\u003e\n\n\u003cp\u003eThe heater hoses carry hot coolant from the engine to the heater core (the small radiator in your dash that makes heat) and back. They see the same coolant, the same heat, and the same pressure as your radiator hoses, which means they age and fail the same way, the rubber dries out, cracks, and eventually leaks.\u003c\/p\u003e\n\n\u003cp\u003eThe problem is they're less visible than the main radiator hoses, so people replace the obvious ones and leave the heater hoses as the weak link. A heater hose leak dumps coolant just like any other, and often in an awkward spot near the firewall. If you're refreshing the cooling system on an EF, these belong on the list.\u003c\/p\u003e\n\n\u003ch4\u003eWhy Silicone\u003c\/h4\u003e\n\n\u003cp\u003eSame reason the rest of your cooling system should be silicone.\u003c\/p\u003e\n\n\u003cp\u003eRubber hoses degrade from the inside out over decades of heat cycling, cracking and ballooning until they leak. Silicone doesn't have that failure mode, it handles heat and pressure far better and holds up without drying or cracking. These are built from high-grade silicone with \u003cstrong\u003eheat-resistant embedded fibers\u003c\/strong\u003e, rated to \u003cstrong\u003e330°F\u003c\/strong\u003e with greater pressure tolerance than the factory rubber. Fit them once and they're not something you'll revisit.\u003c\/p\u003e\n\n\u003ch4\u003eDirect OEM Fit\u003c\/h4\u003e\n\n\u003cp\u003eThese are engineered for a direct OEM replacement fit, so they route and connect exactly where the factory heater hoses did, no modification. Pull the old rubber, fit the silicone, done.\u003c\/p\u003e\n\n\u003ch4\u003eDo Them With The Radiator Hoses\u003c\/h4\u003e\n\n\u003cp\u003eThe sensible way to approach it.\u003c\/p\u003e\n\n\u003cp\u003eIf you're replacing the \u003ca href=\"https:\/\/www.hybrid-racing.com\/products\/mishimoto-silicone-radiator-hoses-88-91-civic-crx\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eradiator hoses\u003c\/a\u003e on your EF, the heater hoses are right there and the same age, so doing both at once means the whole cooling system's soft lines are fresh rather than leaving the heater hoses to fail next. Together with the radiator and fan shroud, fresh silicone hoses throughout are the complete cooling refresh for these cars. It's the difference between fixing the cooling system once and chasing leaks one hose at a time.\u003c\/p\u003e\n\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\n\u003cp\u003e1988-1991 Honda Civic\u003c\/p\u003e\n\n\u003cp\u003ePart number MMHOSE-CIV-88HH.

Silicone rated to 330°F, a direct OEM fit, and the hose most people forget until it leaks.
