Procedure:
1. Park the machine following the same procedures as
described on page 7-7 for preparation for inspection and
maintenance.
2. Remove the under cover for ZX17U-5A. Remove radiator
cap (1). Open drain cock (2) on the radiator and the drain
cock on the water jacket to allow the coolant to drain
completely. Remove impurities such as scale at the same
time.
3. Close drain cock (2) and the drain cock on the water
jacket. Fill the radiator with soft water containing fewer
impurities and a radiator cleaner agent. Run the engine
at a speed slightly higher than slow idle to raise the
coolant temperature until the first two segments come
on. Then, run the engine further for about 10 minutes.
4. Stop the engine and open radiator drain cock (2). Flush
out the cooling system with tap water, until draining
water is clear. This helps remove rust and sediment.
5. Close drain cock (2) on the radiator. Fill the radiator with
tap water and LLC at the specified mixing ratio. When
adding coolant, do so slowly to avoid mixing air bubbles
in the system. Run the engine to sufficiently bleed air
from the cooling system.
6. After adding coolant, operate the engine for several
minutes. Check the coolant level again, and add coolant
if necessary.
