SERVICE AND MAINTENANCE
Engine Service
Routine service can be done by opening the rear cargo box lid using the latch. Forward of the cargo box is
an access cover for checking fluid levels; coolant, engine oil and transaxle.
Improved access to the engine/transaxle is provided by removing the rear cargo box.
1. Open box lid by unlocking rear latch.
2. Unscrew and withdraw ‘wing nut stud’ that affixes cargo box to frame.
3. You and another person lift the rear of the cargo box slightly, slide backward, and remove.
Re-install cargo box using opposite procedures of disassembly.
Air Cleaner Element
The air cleaner element is a dry type air cleaner. It is chemically treated, pleated paper-air-filtering element
which permits air flow through the air induction system, filtering out unwanted dust, dirt, and debris.
Replace air filter every 30,000 miles (1000 hours). Replace every 15,000 miles (500 hours) or whichever
comes first under severe operating conditions.
Access to air filter is done by:
1. Remove the cargo box (or slide rearward for access) as above.
2. Release the two latches on air cleaner housing cover.
3. Lift the air cleaner housing cover and air cleaner element.
4. Remove the air cleaner element.
5. To install, reverse the removal procedure.
Engine Oil
Proper amount of oil in the engine is important for safe operation. Check every time you add fuel to your
vehicle. For accurate reading make sure the vehicle is on a level surface and the oil is warm.
Check oil
1. Turn off engine after the oil is warm (2-3 minutes of running).
2. Locate the oil dipstick, on the side of engine.
3. Pull out dipstick, wipe clean and replace.
4. Pull out dipstick once again and read it. If the oil level is below the letter “F” or reads at 0.8L, add
oil until it reads at the line below “F”.
Adding Oil
1. Locate the oil filler cap on top of engine. Remove it.
2. Add desired amount of oil.
3. Let it sit a couple of minutes and recheck oil (as above) to insure proper level.
4. Replace filler cap.
Choosing the Right Viscosity Grade
You must consider the temperature in which you drive your GO-4. If you regularly drive in
temperatures that are below 100 F (38 C), use SAE 5W-20/GF4&SM oil. If you drive regularly at
temperatures above 100 F (38 C), use SAE 10W30 oil. If you regularly drive in temperatures that
are below 20 F (-10 C), use SAE 5W20 oil.
