COOLANT SYSTEM
Blowing Out Radiator Fins
NOTE: Make sure radiator is cool before blowing
out the radiator fins with compressed air.
Use maximum compressed air pressure of
100 p.s.i. to blow out radiator fins with.
Reverse Flow Flushing
1. At the engine, disconnect the hoses.
2. Make sure the radiator cap is on tight.
3. Using a hose clamp, attach a flushing gun onto the
lower hose.
4. Turn on the water and fill the radiator.
5. To keep from damaging the radiator, apply air
pressure slowly and carefully.
6. Shut off the air pressure, refill the radiator with
water, and reapply the air pressure. You will need
to repeat these steps until water flushed from the
radiator runs out clear.
7. Inspect and clean the radiator cap.
8. Inspect and reconnect the hoses.
9. Refill the radiator with coolant.
NOTE: Use a 50/50 mixture of water and an anti-
freeze with an ethylene glycol base.
ATTENTION!
Plain Water, Alcohol or Methanol base antifreeze
is not recommended for use in the cooling
system at anytime!
