C-30HDNI (PRECISION) PUMP — INSPECTION
Checking Engine Coolant Level
1. Remove the radiator cap, and check the cooling water level
inside the radiator (Figure 18).
2. Maintain water/coolant level at top of radiator coils.

V-Belt Deflection
1. Visually inspect the V-belt for cracks, fraying, wear or oiliness.
2. Make sure V-belt does not the bottom the pulley groove.
3. Check the V-belt tension (Figure 19) by pushing midway through
the two pulleys. The V-belt deflection should be between .300 to
.472 inches (8 to 12 mm).
NEVER remove the radiator cap when the
engine is HOT! Allow the engine to cool
before remove the cap.
WARNING - Burn Hazards
3. Check the radiator and hoses for any signs of leakage.
4. If cooling water is dirty, flush the cooling system.
5. When using antifreeze, mix the antifreeze coolant with water.
Observe the instructions on the antifreeze container. Usually
a 50/50 mixture is a good choice.
6. When replacing the radiator cap, be sure to fit it securely back
onto the radiator. If replaced loosely or incorrectly, the cooling
water will quickly evaporate, causing the engine to overheat.)
