Diagnosis is one of the most important aspects of UTV maintenance. If you do not know where the problem stems from, you will not know where to focus your attention and what replacement parts you may need. With that in mind, Team Winnebagoland Powersports Center has created this guide to troubleshooting maintenance problems in your UTV.

Battery Issues

There are several things that can go wrong with your side-by-side’s battery. For example, if the starter doesn’t function properly, it may be because the battery is dead or not charged enough. You can charge an undercharged battery using a tender, though a dead battery will require total replacement. If these steps don’t help, you may be dealing with a poor terminal connection. In this case, apply grease to the terminals, treat them with an anti-corrosive, and tighten them securely. If the problem is that your battery is not recharging anymore, it is time for a replacement. Finally, if you have a refillable battery and the electrolyte levels are dropping too rapidly, it may indicate a crack or hole in the cell. Unfortunately, your only recourse will be to replace it. 

Engine Trouble 

If your UTV’s engine isn’t starting correctly or isn’t putting out as much power as it should, there could be a number of causes. For example, a lack of engine power can be caused by a clogged injector, an empty fuel tank, a dirty or broken spark plug, a ruined ignition coil, or a wrecked crankshaft position sensor. Make sure that you check these parts to see if they need to be refilled, cleaned, or replaced. 

An overheating engine is another common maintenance problem. If your UTV’s engine overheats, it may be due to a malfunctioning coolant system. Top off your coolant levels when they get low, and flush your cooling system if you find evidence of a corroded coolant flow path. Your engine may also overheat if you have a loose or broken radiator cap or a motor-driven fan that isn’t turning due to a broken fuse. Make sure you make any replacements/adjustments necessary to address these issues. 

An engine that struggles to start may be caused by low fuel flow. If you have trouble getting your UTV’s engine to start, inspect the fuel tank, filter, electric fuel pump, and injector. A loose fuel tank cover may also be to blame, as this can allow water to get into the fuel system. In this case, you will have to drain and refill your quad’s fuel. A third possible cause is a weak battery, which can be fixed by recharging it or cleaning the terminals. 

General Problems

While UTV issues stemming from the battery or engine are fairly easy to identify and address, these are not the only issues you will have to look out for. For example, brakes that grind or fail may be caused by a lack of brake oil, the presence of air in the braking system, or a loose plate or clippers that need tightening. If your transmission is making an unusual noise, it may be time to replace the gears. Finally, a lack of vehicle power may be caused by a sliding CVT transmission, requiring that you replace the transmission belt or clutch. Alternatively, you want to take a look at your brakes, as a lack of vehicle power can also be caused by a malfunctioning parking brake or disc brakes that aren’t uncoupling completely.
