SYSTEM TESTING

COOLANT (HYDROMETER TEST)

Remove the screw [1] and radiator cap [2].
Test the coolant gravity using a hydrometer (see below
for "Coolant gravity chart").
For maximum corrosion protection, a 1:1 solution of
ethylene glycol and distilled water is recommended
(page 8-6).
Look for contamination and replace the coolant if
necessary.
