Ford Ranger (2011 year). Manual — part 56

State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.

WARNING: If you operate your vehicle in temperatures below
40°F (5°C), use washer fluid with antifreeze protection. Failure

to use washer fluid with antifreeze protection in cold weather could
result in impaired windshield vision and increase the risk of injury or
accident.

Note: Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling system
components.

CHANGING THE WIPER BLADES

1. Pull the wiper arm away from the
vehicle. Turn the blade at an angle
from the wiper arm. Press the lock
tab to release the blade and pull the
wiper blade down toward the
windshield to remove it from the
arm.

2. Attach the new wiper to the
wiper arm and press it into place
until a click is heard.

Replace wiper blades at least once per year for optimum performance.

Poor wiper quality can be improved by cleaning the wiper blades and the
windshield. Refer to Windows and wiper blades in the Cleaning
chapter.

To prolong the life of the wiper blades, it is highly recommended to
scrape off the ice on the windshield before turning on the wipers. The
layer of ice has many sharp edges and can damage the micro edge of the
wiper rubber element.

• If the oil level is below the lower hole or the MIN mark, add enough

oil to raise the level between the two holes or between the MIN-MAX
range.

• Oil levels above the upper hole or MAX mark may cause engine

damage. Some oil must be removed from the engine by an authorized
dealer.

7. Put the dipstick back in and ensure it is fully seated.

Adding engine oil

1. Check the engine oil. For instructions, refer to Checking the engine
oil in this chapter.

2. If the engine oil level is not within the normal range, add only certified
engine oil of the recommended viscosity. Remove the engine oil filler cap
and use a funnel to pour the engine oil into the opening.

3. Recheck the engine oil level. Make sure the oil level is within the
normal range on the engine oil level dipstick.

4. Install the dipstick and ensure it is fully seated.

5. Fully install the engine oil filler cap by turning the filler cap 1/4 turn
until it stops.

To avoid possible oil loss, DO NOT operate the vehicle with the
engine oil level dipstick and/or the engine oil filler cap removed.
