Power  Steering  Fluid 
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 
When  the engine  compartment is cool, 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. 
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 
“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 YOLI 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 
fdll below  freezing,  use a fluid that has sufficient 
protection against  freezing.
