Power Electronics Coolant
WARNING: Steam and
scalding liquids from a hot
cooling system can blow
out and burn you badly.
Never turn the cap when the
cooling system, including the
power electronics coolant
tank pressure cap, is hot. Wait
for the cooling system and
reservoir tank pressure cap to
cool.
The power electronics coolant tank is
located under the hood, on the left side,
next to the low voltage fuse center.
1. Remove the power electronics
coolant tank pressure cap when
the cooling system is no longer
pressurized.
2. Keep turning the pressure cap,
but now push down as you turn
it. Remove the pressure cap.
3. Fill the reservoir with the proper
mixture of 50% DEX-COOL® and
deionized water, 1/2 inch below
the bleed fi tting.
4. Replace the pressure cap.

Checking the fl uid level:
Service and Maintenance 27
1. Remove the dipstick from the
coolant reservoir. Wipe clean.
2. Push it back in all the way, wait
three seconds, and pull it back
out again.
3. Check both sides of the dipstick,
and read the lower level. The
fl uid level must be between the 2
indicators on the dipstick. Be sure
to keep the dipstick pointed down
to get an accurate reading.
4. If the fl uid level is in the
acceptable range, push the
dipstick back in all the way, then
fl ip the handle down to lock the
dipstick in place.
To add fl uid:
Using a clean funnel, add fl uid down
the dipstick tube only after checking
the fl uid while it is cold. If the fl uid level
is low, add only enough of the proper
fl uid to bring the level up to the middle
range of the dipstick. If fl uid is needed,
use only DEXRON®-VI Automatic
Transmission Fluid. It does not take
much fl uid, generally less than
0.5 L (1 pt). Do not overfi ll.
