Radiator Maintenance
1. Check radiator for leaks that would indicate corrosion
or damage.
2. Check coolant level daily. Top off as necessary. Always
use recommended coolant/antifreeze. Use the mixing
ratios specified by the coolant/antifreeze manufacturer or
Table 7. Replace coolant/antifreeze at least once a year.
3. Check radiator hoses for fatigue, softening, kinks or
cracking. Replace any defective hoses immediately.
Check clamps for signs of leakage.
4. Check radiator cap seal and replace as necessary.
5. Blow off dirt and dust from fins and radiator with 28 psi
(193 kPa) or less of compressed air (Figure 46). Be
careful not to damage the fins with the compressed air.
Figure 46. Radiator Cleaning
6. If there is a large amount of contamination on the fins,
use detergent to clean and rinse thoroughly with tap
water.
NOTICE
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.
MAINTENANCE
Fuel Filter
Replace the engine in-line fuel filter (Figure 47) every year or
300 hours.
Figure 47. In-Line Fuel Filter
Oil And Fuel Lines
1. Check the oil and fuel lines and connections regularly
for leaks or damage. Repair or replace as necessary.
2. Replace the oil and fuel lines every two years to
maintain the lines’ performance and flexibility.
V-BELT
Visually examine the V-belt (Figure 48) and determine if it
is full of tiny cracks, frayed, has pieces of rubber missing,
is peeling or otherwise damaged.
Also, examine the belt and determine if it is
oil soaked
or
“glazed”
(hard shiny appearance on the sides of the belt).
Either of these two conditions can cause the belt to run hot,
which can weaken it and increase the danger of it breaking.
If the V-belt exhibits any of the above wear conditions
replace the V-belt immediately.
