    Perfect!

    Comments On Jan 12, 2016:450's tend to run hot, especially on trails. The CV4 cap is cheap protection against a boil over. Highly recommend.

    Part of the solution to the overheating puzzle...

    Comments On Dec 04, 2015:Works great in conjunction with engine ice or water wetter to keep your bike running cooler

    29 psi

    Comments On Dec 05, 2015:bought the highest pressure cap I could to keep from boiling over. I ride 115 degree summers on tight trails and haven't had an issue since I installed this cap. I know it doesn't lower operating temps at all but at least im not losing coolant making my situation worse.

    Works as designed, keeps engine running optimally

    Comments On Sep 28, 2015: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."

    Works as advertised

    Comments On Sep 22, 2015:This cap keeps the coolant where it belongs - so much so that I removed the overflow bottle from my WR. Even in the heat of summer with some slow-speed trail sections, it doesn't lose any coolant. If you go this route, just be aware that it puts greater pressure on the rest of your cooling system seals and components. No issue for a healthy system.

    Raises boiling point of coolant

    Comments On Aug 14, 2015:It does what it is intended to do. It raises the boiling point of coolant. The only complaint is that it is a real pain to turn to remove. It is on very tight. I usually put on a pair of mechanics gloves to get enough grip to turn the cap.
