  • 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."

  • Tusk In Line Water Cooler

    Tusk In Line Water Cooler

    Branden in PA

    Not sure if it works, but installs easily!

    An inline water cooler like this maybe gives more peace of mind than anything else because I have no way of measuring whether or not it's actually dissipating heat efficiently. But my wife's smaller 271cc liquid-cooled engine works very hard when we're on the trails, and I wanted to make sure she had every advantage in cooling possible. Hoping this isn't just a gimmick product, but it's well-made, inexpensive, and can't hurt the engine any. :)

  • Cycle Logic Engine Ice

    Cycle Logic Engine Ice

    Branden in PA

    Big difference in engine cooling efficiency

    Engine Ice doesn't make your engine run "colder," so not sure of those claims. Engines are made to operate in an optimal temperature range, so what this does is allows your engine to dissipate heat a WHOLE lot better. In other words, whereas stock coolant may boil over when riding slower trails where the engine is working really hard (rock climbing, etc.), Engine Ice handles it more efficiently and dissipates the heat better. Under those loads, the reduction in temperature is really a prevention of the INCREASE in temperature by up to 50-degrees. I can tell the difference already. The radiator fan doesn't come on nearly as often, and my temperature gauge rarely, if ever goes above 2 clicks now (used to hit 3 on an average ride). I think the engine is benefiting from this better coolant. And for the price, you really can't beat this upgrade in cooling efficiency. :)
