Golf carts may look like low-key transportation for use on a field only, but they are motor vehicles that require care, just like a regular street-legal car. The engine on a golf cart needs to be in very good shape because these are used by people who may not be able to walk all the way back to the the main building on a property, be that a clubhouse on a golf course or a warehouse on an industrial site. Having the carts go out of commission for repairs can be inconvenient. A few engine maintenance tasks can keep the carts running well for a long time.
Use Extra-Tough Batteries
These carts see some pretty wild environmental conditions because they aren't enclosed vehicles like cars. The batteries have to be extra tough in case moisture finds its way into the engine. The carts also need to be on the go constantly; they don't sit in a lot for eight hours and get driven only for a couple. They are a primary mode of transport for hours each day, which can be tough on even the sturdiest of car batteries. Vehicle batteries made specifically for golf carts, marine environments, and similar conditions -- like Trojan batteries -- are best.
Wash the Cart Frequently
With all the outside driving they are put through, it's natural that golf carts would get a bit dirty. But don't limit cleaning to every few months or to just the exterior hard surfaces. Give each cart a thorough cleaning -- not just a brief wash, but a "find all the dirt" scouring -- on a weekly basis if not a little more frequently. The dirt can easily work its way into the pedal assembly and other parts of the cart, eventually making its way into the engine.
Check Electrolyte Levels
If you have an electric-only cart, you'll need to check and top off the electrolyte water levels every week. This helps keep the battery and engine running smoothly.
Test the Reverse Buzzer
Outdoor golf carts are often in areas where there is either a lot of noise, or you have a lot of people concentrating on something else and not on looking out for random carts. If you have to reverse, you need a working buzzer to alert people behind you. Always test that buzzer, at least once a week if not daily. If the buzzer is no longer working, obviously, you have to check the buzzer itself, but it's a sign that the engine may need a checkup.
Bringing the cart in for a professional checkup on a regular basis is essential, too, so that things like the battery can be replaced when needed. With the right care, the battery and other engine components will last a long time.
