Steps To Change Water Coolant (Cold Cycle Cleaning) - PGO Tigra AF-125BAE Service Manual

7. During the coolant temperature gradually increased to the
circulating temperature, some bubbles from coolant will be
observed at the inlet (residual air evacuated by the system).
8. Stop the engine and check coolant for addition in the event of
no bubble observed at the inlet and the coolant level stable.
9. Keep watch for the coolant level of the auxiliary water tank at
the first three drives with the water coolant having been
changed. Please add any water coolant up to the standard
level, if necessary.

 Steps to change water coolant (cold cycle cleaning):
1. Remove the thermostat cover; take out the thermostat; open a
water tank cover.
2. Start the engine; loosen the drain plug bolt on the water pump
cover to evacuate water coolant and add new coolant
simultaneously for cycle cleaning (with the engine running).
* During cleaning, other substitutes such as clean soft water
or distilled water can be used to replace water coolant;
however, the coolant is still added with cleaning finished.
3. Keep watch for water coolant evacuated from the drain
during cycle cleaning. There has been 90% water coolant
replaced in the event of the color of water coolant identical to
that of new coolant.
4. Keep cleaning to consume 2,000cc coolant.
5. Install the drain plug bolt with cleaning finished; check the water coolant level and add it
up to the maximum level.
