Note
Do not use bottled drinking water because it often contains higher
concentrations of total dissolved solids.
6.11.2 Coolant Water Quality
Water quality is important to the performance of the cooling system. Distilled,
deionized, or demineralized water is recommended for mixing with antifreeze.
The water used in the cooling system must be clean and clear and should meet the
following minimum specifications for quality:
Water that deviates from the values in the table must be conditioned.
6.11.3 Draining the Cooling System
1. Stop the truck in a designated service
area.
2. Lower the forks fully and tilt the forks
forward fully.
3. Turn the ignition key switch to the ‘0’ (off)
position, then remove the key.
4. Allow the radiator to cool down.
5. Open the bonnet (A) fully.
6. Remove the access panel (B) from the
right-hand side of the truck (pull out
firmly at the top then lift up and out).
7. Remove the cap (C) from the top of the
radiator. Turn the cap anticlockwise
gradually to slowly release any pressure
before removing fully.
8. Place a suitable container on the
ground next to the drain plug (D) to
collect the used coolant.
9. Unscrew the drain plug and allow time
for the coolant to drain completely from
the system.
Tip: Use a funnel or hose to channel
the used coolant into the collection
container.
10. Refit the radiator drain plug (D) with a new seal and tighten into the radiator.
