Pontiac 2005 Bonneville - Manual (Page 312)

Start the engine and allow it to warm up. If the LOW
ENGINE COOLANT message does not appear on
the Driver Information Center (DIC), the coolant is at the
proper fill level. If a LOW ENGINE COOLANT message
does appear, repeat Steps 1 to 3 then reinstall the
pressure cap, or see your dealer.
Power Steering Fluid
The power steering fluid
reservoir is located in the
rear of the engine
compartment on the
passenger’s side of the
vehicle. See Engine
Compartment Overview
on page 5-12 for 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 at the FULL COLD mark.
If necessary, add only enough fluid to bring the
level up to the mark.
What to Use
To determine what kind of fluid to use, see Part D:
Recommended Fluids and Lubricants on page 6-24.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
