Cooling system is provided with ELC (pink colored) coolant from
the factory. However, green coolant may be used to top off.
At first annual service, drain ELC and replace with A-A-52624
coolant (WP 0042 00).
A freeze protection indication other than -50F (-47C) requires
corrective action. Partially drain coolant and replace with water or
antifreeze to bring freeze protection to -50F (-47C).
Do not test strip at temperatures below 50F (10C) or above
85F (30C).
a. Use test strip to check for proper
freeze point and nitrite level. If levels
are out of specification, drain and
refill cooling system (WP 0042 00).
b. Test for reserve corrosion protection
using test strip.
