Mishimoto Radiator Hoses for 94-01 Integra GS/LS/RS/GS-R

Compatible with B18B1 and B18C1 Engines Direct Replacement Part Fits 94-01 Integra GS/LS/RS/GS-R Resistant To Heat Up to 330 F Description Vehicle Fitment Included Mishimoto Silicone Radiator Hoses - 94-01 Integra Your stock rubber radiator hoses are twenty years old and you're wondering when they're going to blow? They probably look fine from the outside but the rubber's cooked from two decades of heat cycles. We've seen stock Integra radiator hoses crack at the bends, swell up soft, or just split wide open and dump all your coolant on the ground. Usually happens when you're on the highway, not sitting in your driveway. Mishimoto's silicone radiator hose kit replaces those old rubber hoses with high-grade silicone that actually handles heat. The silicone doesn't get brittle like rubber does. It doesn't crack, it doesn't swell, and it's not going to fail on you in five years. These hoses are built with dual layers - silicone on the outside and heat-resistant fibers embedded inside so they don't balloon when your cooling system's under pressure. They're a direct bolt-in replacement for your stock hoses. No cutting, no trimming, no making anything fit. You're swapping hoses and you're done. Here's What Kills Stock Rubber Hoses Your Integra's radiator hoses have been heating up and cooling down since the '90s. Every single time your motor gets hot, the rubber expands. When it cools down, the rubber contracts. Do that a few thousand times over twenty-plus years and the rubber turns hard and brittle. It'll crack right at the bend where it connects to your radiator or your thermostat housing. Sometimes you'll see the hose get fat and squishy because the internal structure's breaking down from heat. That's your warning sign it's about to blow. When a radiator hose lets go, you're losing all your coolant in under a minute. Your temp gauge pegs, your motor overheats, and if you don't shut it down immediately you're warping your head or blowing your head gasket. We've towed plenty of Integras that kept driving after the temp light came on. Don't be that guy. Silicone doesn't age like rubber. It stays flexible at 330°F. Your coolant only runs around 190°F so you've got a huge margin. The hose stays the same whether it's got 1,000 miles on it or 100,000 miles on it. Why Silicone's Better Than Rubber Mishimoto builds these with two layers working together. The outside's high-grade silicone rated to 330°F. That's way hotter than your coolant ever gets so the material's not breaking down. The inside's got heat-resistant fibers embedded in the silicone. Those fibers are there to stop the hose from ballooning when your cooling system's hot and pressurized. Stock rubber hoses will swell up when they're old and the system's under pressure. You can actually see them get fatter when the motor's hot. That's bad because now your hose diameter's changing and you've got a weak spot that's going to rupture. The embedded fibers in the Mishimoto hoses prevent that. The hose stays the same diameter whether your motor's cold or it's hot and sitting at 15 PSI. Consistent diameter means consistent coolant flow and no weak spots waiting to blow. These Drop Right In Mishimoto designed these hoses to fit exactly where your stock hoses go. Same bends, same length, same connection points at the radiator and thermostat housing. You're not trimming anything or trying to make them fit. Pull off your old crusty rubber hoses, clamp on the Mishimoto silicone hoses, refill your coolant, burp the air out of the system, done. The kit's got both hoses - upper and lower radiator hoses. That's everything you need to replace the main cooling hoses on your motor.

The Type R uses completely different radiator hose routing because of the different head and radiator setup. When you're doing this job, throw out your old hose clamps and use new worm-gear clamps or spring clamps. Don't reuse twenty-year-old clamps on brand new hoses - that's asking for a leak. After you've got the hoses installed and you've refilled your coolant, you need to burp the cooling system properly or you're going to have air pockets. Run the motor with the radiator cap off until the thermostat opens and you see coolant circulating. Keep the revs around 2,000 RPM and watch for air bubbles coming up. When the bubbles stop, top off the coolant and put the cap back on. Let the motor come up to temp and check every hose connection for leaks. If you're seeing any seepage at the clamps, snug them down another quarter turn. Silicone's slicker than rubber so the clamps need to be tight. Don't crank them down so hard you cut into the hose, but make sure they're not loose either. 1994-2001 Acura Integra GS/LS/RS/Special Edition1994-2001 Acura Integra GS-R *Does Not Fit Integra Type R (1) Upper Radiator Hose(1) Lower Radiator Hose
