MAINTENANCE
3. Check radiator hoses for fatigue or cracking. Replace
if in doubt of the integrity of the hoses.
4. Check radiator cap seal and replace as necessary.
Refer to your engine manual for additional information.
RADIATOR CLEANING
1. Blow off dirt and dust from fins and radiator with 28 psi
(0.19 MPa) or less of compressed air (Figure 23). Be
careful not to damage the fins with the compressed air.
2. If there a large amount of contamination on the fins, use
detergent to clean and rinse thoroughly with tap water.
.
Figure 23. Radiator Cleaning
CAUTION
NEVER use high-pressure water or compressed air at
greater than 28 psi (193 kPa) or a wire brush to clean
the radiator fins. Radiator fins damage easily.
FAN BELT TENSION
A slack fan belt may contribute to overheating, or to
insufficient charging of the battery. Inspect the fan belt for
damage and wear and adjust it in accordance with the
Yanmar Engine Owner’s Manual.
The fan belt tension is proper if the fan belt bends 10 to 14
mm when depressed with the thumb as shown in Figure 24.

ENGINE OIL
1. When checking or adding oil, place the machine so
the engine is level.
2. Pull the engine oil dipstick from its holder.
3. Determine if engine oil is low. Oil should be between
the upper limit and lower limit (add oil) lines.
4. If oil is below the "Add Engine Oil" line add oil up
to upper limit on the dipstick. Allow enough time for
any added oil to make its way to the oil pan before
rechecking.
