Cooling Systems
Normal running Temperature for Cooling
190-220 Degrees
What does the W stand for?
Winter
What occurs when you have a Spongy Pedal?
Air in the pedal
What two ingredients make up the ratio for Combustion:
Air&Fuel
Bench Bleeding meaning:
The process of eliminating trapped air from a new or removed master cylinder before installing it in the vehicle
What form of Antifreeze freezes quicker?
Full Strength
What does Oil Viscosity Measure?
How Thick or Thin the oil is
Why are Front Brakes bigger than Rear Brakes?
Because Front brakes do more of the braking/work than Rear Brakes 70:30
Air-Fuel Ratio:
14.7:1
What occurs when you Overtighten and loosen a Serpentine belt:
Overtightening: Puts immense load on the bearings resulting in crushing the internal water pump bearings
Loosen: Can cause a very high-pitched squealing noise
What is the best mixture ratio for Antifreeze concentrate and water?
50/50
What does the number in the oil rating represent?
EX: 5W-30
The Thickness in Cold/Hot Temp
When you experience a Shimmy or vibration in either your steering wheel or your brake pedal
What would be the issue?
Brake pulsation
What is the most Advanced/Recent type of ignition system:
Coil-on-plug or Coil Pack
Ways a Water Pump can go bad:
Internal Seal Failure
Seal&Gasket Leaks
Internal Bearing Wear
Antifreeze 3 Primary Jobs
Prevents Engine From Freezing
Lubrication
Cleaning/Corrosion
Three Primary jobs for Oil:
Lubrication
Cooling
Cleaning
Hydroscopic meaning:
The process of attracting and absorbing moisture from air
What is the purpose of both Superchargers&Turbochargers:
To force extra, compressed air into an engines cylinders. This allows the engine to burn more fuel, resulting in more horsepower.
Purpose of Traction Control, ABS, and Wheel Speed Sensor are all used for what:
Keep each Wheel's MPH even
Why Does This form of Antifreeze freeze quicker?
because the crystals in the water disrupt the process of freezing
Two Different Types of Oil Filters
Spin-On
Cartridge
Pascal Law meaning:
BONUS: What is the Formula
+200 points
when pressure is applied to any part of a fluid, that pressure is transmitted equally in all directions throughout the liquid
P=F/A
Different Types of Ignition Systems:
Coil-On-Plug
Wasted Spark
Distributor
Breaker-Less
Mechanical Advantage
The ratio between the force applied by the brake pads(output) and the force applied to the level or pedal(input).
