If you do a lot of to late summer riding, the time is now to check the coolant in your ATV. Coolant levels can drop due to any number of issues, including worn engine components and leaky reservoir bottles or internal seals on your ride. There are several tools available at your local auto parts dealer that can also tell you if the coolant is capable of doing its job or if it may need to be flushed then replaced. One thing to note about the coolant in your ATV is the coolant actually lubricates seals and internal components as well to help properly maintain the system in which the coolant lives. Here are three items to keep the ATV you love running strong in extreme heat or cold.
1. Inspect coolant levels each time you fuel up. If it needs it add it but add the coolant to the overflow bottle and not the radiator itself.
2. Immediately flush the entire system if you begin to notice any discoloration of the fluid or if any debris becomes present.
3. Water will cool the engine but Glycol based antifreeze will prevent internal parts from rusting as well as keep the engine from freezing and potentially damaging the motor.
The coolant is not the only item that needs a regular check up though as the radiator cap can contribute to higher than normal engine temperatures if left unchecked for too long. Radiator caps help pressurize the system for optimal cooling, so be sure to add this to the list of maintenance items to check.
