What can the washer fluid do if it spills
The corrosiveness can harm wiring and electronic components
An exhaust system hose should be connected to the tailpipe when
The engine is being run indoors.
What should you always do to the air filter ?
The inlet passage leading to the air filter for debris that can reduce airflow to the engine.
What should you check in the coolant level in the coolant recovery tank or surge tank
The level and color
Prior to any service work, it is wise to check
The vehicle for damage and document the work order if any damage is found.
What is normal for the brake fluid level to do ?
To drop as the disc brake pads wear.
Blake Fluid
Transmit the force of the driver's foot on the brake pedal, called the service brake, to each individual wheel brake.
What are the two types of brake master cylinders ?
Transparent Reservoir and Metal or Nontransparent Plastic Reservoir
Cabin Filter
Used in the heating, ventilation, and air-conditioning system to filter the outside air drawn into the passenger compartment.
Metal or Nontransparent Plastic Reservoir
Used on older vehicles, requires that the cover be removed to check the level of the brake fluid
How do you test the boiling point of the brake fluid ?
Using a Handheld Tester
DOT 3
Very strong solvent and can even remove paint. Most often used and absorbs 2% of its volume in water per year and moisture from the air. It should be used from a seal (capped) container.
What should maintenance include
Visual inspection for signs of coolant system leaks and for the condition of the coolant hoses and accessory drive belts
Normal Maintenance involves what
an occasional check
Windshield Wiper Blades
are constructed of rubber and tend to become brittle due to age.
On hybrid vehicles you have to make sure of what ?
make sure that the technician has possession of the key transmitter and the vehicle is not in the ready mode before starting any inspection or service procedures

the recommended washer fluid
What should you do with the front of the radiator
Carefully inspect and cleaned of bugs, dirt, or mud that can often restrict airflow
Visual Inspection
Check the color of the brake fluid. It should be clear or almost clear. If the color is dark brown or black then it should be replaced.
-Visual Inspection
Coolant should be clean and close to the color when it was new. If dark or muddy, should be replace. Milky colored coolant is an indication of oil in the system that might be caused by a defective engine gasket
DOT
Department of Transportation
What should you not do with a brake master cylinder ?
Don't overfill because it need room for the brake fluid to expand
Test strips are useful for what ?
Easy-to-method to determine id the brake fluid needs to be replaced
How many times do the service technicians recommend replacing the air filter ?
Every Year
Air Filter
Filters dirt from the air before it enters the intake system of the engine.
Windshield Washer fluid is recommended
For use in vehicle windshield washer system
What is the brake fluid is made from
A combination of various types of glycol, a non-petroleum-based fluid.
DOT 5.1
A non-silicone-based polglycol fluid, it has a boiling point of over 500F (260C) equal to the boiling point of silicone-based DOT 5 fluid. It can be mixed with either DOT 3 or DOT 4
Boiling/Freezing Points (Refractometer and Hydrometer)
Hydrometer can be used to check the freezing and boiling temperatures of the coolant. Refractometer can be used to check the freezing temperature of the coolant.
What color is Dot 5 and why ?
ITs is the color purple so it can be distinguished from DOT 3 and DOT 4 fluid.
Transparent Reservoir
It allows viewing of the brake fluid (and hydraulic clutch master cylinder, if so equipped) without having to remove the cover of the reservoir.
DOT 4 (Low Moisture Absorption)
It is formulated for use by all vehicles. It does not absorb water as fast as DOT 3, it also affected by moisture and should be sealed container and its double the cost of DOT 3
When should the brake fluid be checked ?
It should be checked at the same time the engine oil is changed and every six month (whichever occurs first).
How many times should the air filter be replaced ?
It should be replaced according to the vehicle manufacturer's recommendations.
When should the oil be replaced according to automotive experts ?
It should replace every 5,000 to 7,500 miles (8,000 to 12,000 km) or every six months. Whatever occurs first
What will happen to the air filter over time ?
It will start to clog up and decrease the engine's efficiency.
Oil Level Indicator (Dipstick)
Its clearly marked and in a convenient location
DOT 5 (Silicone Brake Fluid)
Made from polydimethysiloxanes. It does not absorb water and its called nonygroscopic. It should not be mixed with DOT 3 and DOT 4.
Inspection should include
-Exterior Lights -Horn -Windshield Wiper Operation -Mirrors -Defroster Fan Operation -Steering for Excessive Looseness or Leaks -Shock Absorbers that Allows Excessive Body Sway -Tire Condition, Tread Depth, and Proper Inflation Pressure -Parking Brake Operation -Exhaust System for Excessive Noise or Leaks
Exterior Lights

What are the two possible causes of the fluid level being low
-Normal disc brake pad wear (inspect the brakes if the fluid level is low.) -A leak somewhere in the hydraulic brake system (Carefully inspect the entire brake system for leaks if the brakes are not worn and the brake fluid level is low.)
How to check the oil
-Remove the dipstick -Wipe off the oil -Reinsert it all the way down -Remove the dipstick again and check where the oil level touched the indicator
What Personal Protective Equipment
-Safety Glasses. -Hearing Protection, if around air tools or other loud noises. -Gloves, if handling hot objects or chemicals, such as used engine oil.
Cover which areas ?
-Seats -Floor -Steering Wheel
In most dealerships and shops, the responsibility is
-Service Adviser (Service Writer) -Shop Foreman -Shop Owner
Wiper Blade or Wiper Blade Insert Replacement
-Turn the Ignition switch to on (run) -Turn the wiper switch on and operate the wipers -When the wipers are located in an easy-to-reach location, turn the ignition switch off. The wipers should stop -Remove the insert of the entire blade as per service information and/or the instructions on the replacement windshield wiper blade package -After double-checking that the wiper is securely attached, turn the ignition switch on (run) -Turn the wiper switch off and allow the wipers to reach the park position. Check the proper operation
Cabin Air Filter can be Accessed from
-Under the hood at the cowl (bulkhead) -Under the dash, usually behind the glove (instrument panel) compartment (Check service information for the exact location and servicing procedures for the vehicle being serviced.)
Coolant Testing
-Visual Inspection -Test Strips -Boiling/Freezing Points (Refractometer and Hydrometer) Proper Reading
Before starting routine preventative maintenance on a vehicle be sure to
1. Open the hood and held open securely 2. Connect an exhaust system hose to tailpipe before work is started that will involve operating the engine
When it comes to replacing the air filter how much does do the manufacturers recommend
30,000 Miles (50,000 Km), or more frequently under dusty conditions.
Proper Reading
A proper 50-50 mix of the antifreezr and water should result ina freezing temperature of (-34F (-37C)) -If the freezing temperature if higher than -34F (such as -20F), there is too much water in the coolant. -If the freezing temperature is lower than -34F (such as -46F), there is too much antifreeze in the coolant
Test Strips
A quick and easy way to check the condition of the brake fluid is to use test strips. Always follow the instructions that come with the test strip for accurate results.
What does the filter contain to help eliminate odors ?
Activate Charcoal to help eliminate odors.
What fluid should you never use for the windshield washer reservoir ?
Antifreeze
Before most service work is done, protect the inside of the vehicle by using
Available Plastic or Paper Protective Coverings
Test Strips
Available to test the condition of the coolant. Some will work only on the old green inorganic additive technology coolant
Where should the oil level be when the vehicle is on level ground it has been drain into the oil pan ?
Between the MAX and MIN marks
What color are most windshield washer look like
Blue Water
Where should the proper level of the metal or nontransparent plastic reservoir be?
