Adding Washer Fluid; Windshield Washer Fluid - GMC 2000 Sonoma Owner's Manual

How to Check Power Steering Fluid
Turn the key off, let the engine compartment cool down,
wipe the cap and the top of the reservoir clean, then
unscrew the cap and wipe the dipstick with a clean rag.
Replace the cap and completely tighten it. Then remove
the cap again and look at the fluid level on the dipstick.
For the VORTEC 4300 V6 engine, the level should be
between the ADD and FULL marks. For the 2200 L4 engine,
the fluid level should be at the C mark. 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" in the Index.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.

Windshield Washer Fluid

What to Use
When you need windshield washer fluid, be sure to read
the manufacturer's instructions before use. If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.

Adding Washer Fluid
