The role that your radiator plays on your Polaris RZR 4 should not be understated. Your Polaris RZR 4’s radiator is responsible for regulating internal temperatures and reducing the heat output of your Polaris RZR 4’s engine. Without your radiator, your Polaris RZR 4 would become a fiery inferno. Excess heat is probably the single most damaging element to not just your engine, but all the other internal parts and components of your Polaris RZR 4 such as your transmission, drive train, suspension system, and frame. Uncontrolled radiant heat will accelerate the natural wear and tear of your Polaris RZR 4, shortening its lifespan and reducing its resale value. This is why you should always keep close tabs on your Polaris RZR 4’s radiator and ensure it is always doing its job properly.
Unfortunately, a lot of off-road enthusiasts make the mistake of treating their Polaris RZR 4’s radiator as an afterthought. This is a big mistake that can end up costing you a lot. To make matters worse, the Polaris RZR 4’s stock radiator wasn’t designed to perform at the level that aftermarket UTV radiators for the Polaris RZR 4 are designed to. The Polaris RZR 4’s stock radiator also isn’t built to last like aftermarket side by side radiators for the Polaris RZR 4 are. This is why so many Polaris RZR 4 owners end up replacing their stock radiator with an aftermarket Polaris RZR 4 radiator. Whether they make this decision by choice or through necessity, it ends up being a huge upgrade for their Polaris RZR 4 in more ways than one. An aftermarket UTV radiator replacement for the Polaris RZR 4 offers a significant reduction in internal temperatures which in turn ends up allowing the Polaris RZR 4’s engine to perform at the level it was made to. That’s right. If you are still relying on your Polaris RZR 4’s stock radiator, you are sacrificing not just engine performance but the overall off-road riding experience of your Polaris RZR 4.

The stock radiator on the Polaris RZR 4 is surprisingly thin. With slight changes to the front end, under heavy loads, or up hills, it is not uncommon for the Polaris RZR 4 to overheat, blow gaskets, spew coolant, or go into limp mode. If your rig is tuned properly and the fans turn on at lower temps, you’re starting in the right direction. Split tank coolant systems like those by HTC and OHV are also quite good at keeping temperatures down. They remove the thermostat, block off the hot recycle line between the engine and water pump, and split the engine and intercooler radiators into two separate systems, allowing them to each carry their own cooling load. But while split systems, intercooler relocation kits, and tune jobs can help a great deal, in some instances, the best route is to swap out the stock radiator and replace it with an aftermarket Polaris RZR 4 radiator.
The TCP setup, for example, is super nice and one of the best things you can possibly do for your RZR. Not only does the radiator/intercooler/fan mod keep your ride cool, but it also looks cool and is beefy as hell. Sure you can go with a voltage regulator, a reflex kit, or gut the catalytic converter from the OEM muffler to reduce heat, but if you ride in hot climates and push your machine to the max, these quick fixes may not do the trick. Be it a heavy-duty radiator from SuperATV, a radiator/heat exchanger combo from CBR Performance Products, or a complete cooling package from TCP Performance, at Everything Polaris RZR, we’ve got the right parts to prevent your RZR from overheating.
