CFMoto ATV HX500-S, HX500-L 4x4. Service Manual - part 5

Frequent immersion in mud, water or sand
Racing or race-style high RPM use
Prolonged low speed, heavy load operation
Extended idle
Short trip cold weather operation

Pay special attention to the oil level. A rise in oil level during cold weather can indicate contaminants collecting 
in the oil sump or crankcase. Change oil immediately if the oil level begins to rise. Monitor the oil level, and if 
it continues to rise, discontinue use and determine the cause or see your dealer.

Perform these procedures more often for vehicles subjected to severe use.
Have an authorized dealer perform these services.

Improperly performing the procedures marked with a

    

could result in component failure and lead to 

serious injury or death. Have an authorized dealer perform these services.

Perform all services at whichever maintenance interval is reached first.

Always check and change the engine oil at the intervals 
outlined in the Periodic Maintenance Chart beginning on 
page 83.  Always change the oil filter whenever changing oil.

1. Pull outward on the areas shown

.

2. Position the ATV/Quadricycle on a level surface.
3. Start the engine and let it idle for 20-30 seconds. Stop the 

engine.

4. Wait a few minutes until the oil settles.
5. Remove the engine oil filler cap

 and wipe off the 

dipstick

 with a clean rag.

6. Insert the dipstick in the oil filler hole and screwing it in, 

then remove it again to check the oil level.

The engine oil should be between the upper and 

lower limit marks.

7. If the engine oil is at or below the lower limit mark, add 

sufficient oil of the recommended type to raise it to the 
correct level.

8. Insert the dipstick into the oil filler hole, and then tighten 

the oil filler cap.

9. Install the panel.

1. Start the engine, warm it up for several minutes, and then 

turn it off.

and then remove the engine oil filler cap.

3. Remove the engine oil drain bolt

 to drain the oil from 

the crankcase.

6. Remove the oil filter cartridge with an oil filter wrench.

An oil filter wrench is available at a nearby dealer.

7. Apply a light coat of engine oil to the O-ring

 of the new oil 

filter cartridge.

 Make sure the O-ring is seated properly.

is found, turn the engine off immediately and check for the cause.

13. Turn the engine off, and then check the oil level and correct it if necessary.

The rear gear case must be checked for oil leakage before 
each ride. If any leakage is found, have your dealer check 
and repair the ATV/Quadricycle.

1. Place the machine on a level place.
2. Place a container under the rear gear case to collect the 

used oil.

3. Remove the oil filler bolt and the drain bolt to drain the oil.

7. Check for oil leakage. If oil leakage is found, check for the cause.

 Be sure no foreign material enters the rear gear case.

1. Place the machine on a level place.
2. Remove the oil filler bolt and check the oil level. It should be 

up to the brim of the hole. If the level is low, add sufficient oil 
to raise it to the specified level.

3. Install the oil filler bolt and tighten it to the specified torque.

Total amount oil quantity:
0.33 L (0.29 Imp qt, 0.35 US qt)

6. Install the filler bolt and tighten it to the specified torque.
7. Check for oil leakage. If oil leakage is found, check for the cause.

 Be sure no foreign material enters the front gear case.

1. Place the ATV/Quadricycle on a level surface.
2. Check the coolant level in the coolant reservoir when the engine is cold as the coolant level will vary with 

engine temperature.

The coolant should be between the upper and lower limit marks.

3. If the coolant is at or below the lower limit mark, remove 

the reservoir cap, add coolant to the upper limit mark, 
install the reservoir cap, and then install the panel.

 Coolant reservoir capacity(up to the upper limit 

mark):0.3 L (0.26 Imp qt, 0.32 US qt)

Hard water or salt water is harmful to the engine. You 
may use soft water if you can not get distilled water.

If water is added, have your dealer check the 

antifreeze content of the coolant as soon as possible. The radiator fan operation is completely 
automatic. It is switched on or off according to the coolant temperature in the radiator.

1. Place the ATV/Quadricycle on a level surface.
2. Place a container under the engine, and then remove the coolant drain bolt. (Use a trough or a similar object 

as shown to prevent coolant from spilling on the footrest.)

3. Remove the radiator cap.
4. Remove the coolant reservoir cap.

5. Disconnect the hose on the coolant reservoir side, and then 

drain the coolant from the coolant reservoir.

6. After draining the coolant, thoroughly flush the cooling 

system with clean tap water.

7. Replace the coolant drain bolt washer if it is damaged, and 

then tighten the coolant drain bolt to the specified torque.

 Coolant drain bolt tightening torque:

10 N

m (1.0 m

kgf, 7 ft

lbf)

10. Install the coolant reservoir hose.
11. Fill the recommended coolant into the radiator until it is 

full.

 Recommended antifreeze:

High quality ethylene glycol antifreeze containing 
corrosion inhibitors for aluminum engines.
Antifreeze and water mixing ratio:1:1
Total amount:1.9 L (1.67 Imp qt, 2.00 US qt)

Coolant reservoir capacity
(up to the upper limit mark):
0.3 L (0.26 Imp qt, 0.32 US qt)

Hard water or salt water is harmful to the engine. You may 
use soft water if you can not get distilled water.

12. Install the radiator cap.
13. Start the engine and let it idle for several minutes. Stop the 

engine, and then check the coolant level in the radiator. If 
it is low, add more coolant until it reaches the top of the 
radiator.

14. Fill the coolant reservoir with coolant up to the upper limit.
15. Install the coolant reservoir cap and check for coolant 

leakage.

If any leakage is found, have your dealer check 

the cooling system.

16. Install the panels and the front rack.
