1.1 SERVICE NOTES
To reduce the impact on the environment and the maintenance cost, whenever the coolant is drained from any
engine, the service records are to be checked to determine when the coolant was last changed. If more than six
months life is left before the next coolant change, then the following procedure is to be adhered to:
1. W hen dr aining the coolant from the engine, use a c lean container of at least 12 litres capacity and ensur e that
the coolant is not contaminated in the draining process.
2. After repairs have been completed, refill the engine cooling system with the drained coolant.
3. Top up as required, using a 50/50 mix of clean water and ‘New Formula Long Life All Seasons Coolant’ to
Holden Specification HN 2043. Refer 2.2 GLYCOL COOLANT MAINTENANCE and 2.3 CHECKING AND
FILLING COOLING SYSTEM (V6 Engine) or 2.2 CHECKING AND FILLING COOLING SYSTEM
(V6 Supercharged Engine) in the VT Series I and VT Series II Service Information for the necessary
procedures and further information.
