Whether you need a radiator hose to properly cool the engine of your Polaris RS1 or need to replace the entire radiator after nailing a delineator pole, you will find exactly what you need to have your single-seat Razor RS1 back up and running in next to no time. The radiator plays a significant role in the life of your engine, and in particular in managing the temperature of your engine. Because the RS1 uses the same motor as the RZR 1000, the machine runs quite hot, with temperatures getting up to between 205 and 206 degrees Fahrenheit. If you don't break in your RS1 properly -- which lets the rings expand and form a seal on the cylinder -- by keeping your rig in low, you might see some smoke rolling back from your hood coming from the radiator. This is normal, and they do smoke a bit when you first get them from the factory. You should also make sure that all your fluids are up: engine oil, coolant, both differentials, etc. Check your drain plugs to make sure they’re snug. No offense to local Polaris dealerships, but they often overlook small things like this. Slowly work the throttle and give your RS1 a chance for the belt to get its first wear. As for steam, smoke, smells, etc, unless you see obvious signs of something leaking, and the engine sounds good, it’s just “normal” break in stuff. Some will argue and say let it rip from day one, but Polaris doesn't tell you to break it in easy for no reason.So your RS1 radiator is already broken in and you're machine starts to smoke, now what? Well it's probably your radiator overheating. To help prevent this, many riders install radiator scoops to get more fresh air onto the engine -- HMF radiator scoops being the most popular. Radiator relocation kits are also used to move the radiator away from the front end of the machine. And if you want to implant a 2018 turbo and turbo drive line into your RS1, you can use turbo fans in the radiator for added cooling power and wire the variable speed feature of the fan to run at a slower speed when the engine us running to further cool it down. Whatever you need to help your radiator keep things cool in your Polaris RS1, we've got it here at Everything Polaris RZR!
