With premium quality silicone and race inspired design, this HPS silicon Heater hose kit can withstand the harsh high temperature and high pressure operating conditions of the engine yet still maintaining peak efficiency during competition or daily driving. HPS silicone Heater hose kit has all the correct bends and curves for a perfect fit replacement for your OEM rubber coolant hoses, compare to the universal hoses you can get from the local auto store, HPS hose kit is much easier to work with. Max. Temperature Rating: 350 deg. F. 100% Stainless Steel Clamps are included for easy installation. This product fits Jeep 2001-2004 Grand Cherokee WJ 4.7L V8. Remark: Silicone hose water permeation rate is 10 to 15 times greater than standard EPDM rubber hose. Checking water level regularly is highly recommended when silicone coolant hoses are used in a daily driving vehicle.

Way easier to route when than the original hard-lines. I've only had them installed for a few weeks. But so far no leaks or anything detrimental to report.

I highly recommend the use of this product!!! I had two OEM Mopar heater hoses, from the engine firewall up to the water pump. Very expensive replacement from Mopar or from other suppliers. These HPS Silicone Hoses are like magic! First of all, silicone does not expand or shrink, so once replaced, and unlike the old rubber hoses, the silicone hoses won't shrink or expand as the engine cools or heats up. This is important as you won't be constantly tightening hose clamps over and over again like you have to do with rubber heater or radiator hoses. Also HPS provides a set of HPS made stainless steel clamps, these clamps evenly tighten the hose, unlike the crappy clamps from auto supply stores which pinch and cut the rubber of hoses. HPS also sells exact fit silicone radiator hoses for 2002-2004 Jeep Grand Cherokee with V-8 engines, these also come with HPS clamp sets. HPS provides a limited lifetime warranty for silicone hoses used with HPS clamps. I wished I had found HPS clamps and hoses earlier, I would have used them on my radiator, call HPS you will be darn happy you did!!!
