  • CV4 High Pressure Radiator Cap

    CV4 High Pressure Radiator Cap

    Branden in PA

    Works as designed, keeps engine running optimally

    BUYER TAKE NOTE: make sure you know what the pressure range is for your cooling system. If you raise the pressure too high, you could damage every downstream component (water pump, thermostat, hoses, etc.). The 2014-15 Honda Rancher is rate between 15-20 PSI (1.1 - 1.4 bar). Going any higher is dangerous and could void your warranty if you blow the cooling system due to high pressures. I bought the 1.4 bar CV4 cap because that's still within the pressure range for my ATV (20 PSI). Couple this cap with Engine Ice coolant, and my ATV never goes above 2 bars on the temperature gauge. None of this makes the engine run colder - that's dangerous - but it does enable it to run at the optimal temperature consistently across various types of riding. I ride on trails that don't allow high speeds, so the radiator fan used to come on all the time and the temperature would spike. Now, it runs very efficiently. Well worth the small cost. Make sure you do your research before putting a high pressure cap on your ATV. Higher pressure isn't always better, even if it does prevent "boil over."

  • CV4 Radiator Hose Kit

    CV4 Radiator Hose Kit

    Jacob in NY

    Nice color

    The colors are good and the right color to match my KTM, but the inner diameter is a hair smaller than stock hoses. Overall great quality though!

  • Hot Rods Water Pump Repair Kit

    Hot Rods Water Pump Repair Kit

    Jeff in CA

    great OEM replacement with perfect fit

    I had issues with the previous owner's work on this bike and had to replace the internals of the water pump. The Hot Rods kit dropped in perfectly and replaced every piece of the water pump. It's now a year and a half later and the kit is still rock solid.

  • Motion Pro Coolant Recovery Tank

    Motion Pro Coolant Recovery Tank

    Eddy in WA

    Overflow tank

    Great little tank, small enough to fit in many places and enough tubing options can work for most applications.
