2010 GMC CANYON radiator

6. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine cooling fan.7. By this time, the coolant level inside the radiator
filler neck might be lower. If the level is lower, add
more of the proper DEX-COOL
®coolant mixture
through the filler neck until the level reaches
the base of the filler neck.
8. Then replace the pressure cap.
At any time during this procedure if coolant begins to
flow out of the filler neck, reinstall the pressure cap.
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.

Power Steering Fluid
The power steering fluid
reservoir is located near
the front of the engine
compartment, behind the
radiator. SeeEngine
Compartment Overview
on page 6-12for reservoir
location.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering fluid
unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How to Check Power Steering Fluid
1. Turn the key off and let the engine compartment
cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with a
clean rag.
4. Replace the cap and completely tighten it.
5. Then remove the cap again and look at the fluid
level on the dipstick.
The level should be between the ADD and FULL marks.
If necessary, add only enough fluid to bring the level
up to the proper range.
What to Use
To determine what kind of fluid to use, see
Recommended Fluids and Lubricants on page 7-10.
Always use the proper fluid.
Notice:Use of the incorrect uid may damage the
vehicle and the damages may not be covered by the
vehicle’s warranty. Always use the correct uid listed
inRecommended Fluids and Lubricants on page 7-10.
