If you’re doing any work on your RZR’s cooling system yourself, you might find yourself with air in the cooling fluid lines. While you can access the cooling system bleeder screw via a small door between the seats through the cover for the oil filter and take it off with an 8mm socket with a swivel and extension, it’s way easier to use a burping funnel and simply let your RZR run for 10 minutes. You can pull the front of your bike up on a hill and bleed the air out without having to mess around with the bleeder screw. Just get the front higher than the back. If you have a winch, hook it up to a tree branch and lift the front up a tad. If you’ve done this properly but coolant is still filling up the reservoir and pissing out of the red, replace the thermostat and water pump. Should this still not fix the issue, the problem is likely with your RZR’s head gasket -- that is, unless you have oil mixed in there as well, then maybe the inner water pump seal to the engine oil passages is blown. Replacing the head gasket isn’t super difficult, but be sure and replace the bolts and studs with good ARP or alike Fasteners. And don't cut any corners, even if it takes a little longer to get it right. If you have any questions about how to fix your Polaris RZR cooling system or the parts/tools required, give us a holler and we’ll make sure your rig is cool as a cucumber.
