Wow, I Wish I Was Only 30!
Wow, I Wish I Was Only 30!
For 30 years, we have watched, reported and written about the view from the automotive aftermarket parts counter. Over the years, many trends have come and gone. Things have changed!
ASE P2 TEST PRIMER: Emissions Control Systems
Emissions are tightly regulated and must not exceed federal limits.
ASE P2 TEST PRIMER: Cooling Systems
Radiators in most late-model vehicles are aluminum with plastic end tanks. Most older vehicles have copper/brass radiators.
On vehicles equipped with antilock brakes (ABS), additional parts include up to four wheel-speed sensors, the ABS hydraulic modulator unit and control module, a pump motor and accumulator (which may not be used on some older systems) and an ABS warni...
ASE P2 TEST PRIMER: Automatic Transmission/Transaxle
Automatic transmissions are mostly used with Rear-Wheel Drive (RWD) while automatic transaxles are used with Front-Wheel Drive (FWD). All-Wheel Drive (AWD) and Four-Wheel Drive (4WD) vehicles may use either a transmission or transaxle depending on th...
ASE P2 TEST PRIMER: Heating, Ventilation And Air Conditioning (HVAC)
Loss of refrigerant is the most common cause of A/C cooling problems.
ASE P2 TEST PRIMER: Exhaust System
Exhaust leaks are dangerous because of the risk of carbon monoxide poisoning. Leaks may occur in mufflers or pipes due to rust or damage, at pipe connections, or where the exhaust manifold mates to the cylinder head. Cast iron exhaust manifolds may a...
ASE P2 TEST PRIMER: Engine Mechanical Parts
To find the correct replacement parts, you must know the vehicle year, make and model, engine displacement in cubic inches (CID) or liters (L), and often the engine code or vehicle identification number (VIN).
ASE P2 TEST PRIMER: Electrical/Electronic Systems
All passenger car and light truck electrical systems operate on 12 volts Direct Current (DC) with the body or chassis providing the negative electrical ground.
ASE P2 TEST PRIMER: Drivetrain Components
Driveshafts may be one piece or two pieces with a center carrier support bearing, and have either U-joints or CV-joints on the ends.
ASE P2 TEST PRIMER: Suspension and Steering
Major components in the suspension include springs (coil, leaf, torsion bar and air springs), shock absorbers and/or struts (twin tube or monotube, low or high pressure gas charged, and some may be electronically adjustable), control arms and bushing...
ASE P2 TEST PRIMER: Manual Transmission/Transaxle
The clutch couples the engine to the transmission, and transmits torque from the flywheel to the transmission input shaft.
ASE P2 TEST PRIMER: Ignition System
Distributorless Ignition Systems (DIS) include "waste spark" DIS systems with coil packs and plug wires, Coil-On-Plug (COP) ignitions (one coil per spark plug), and Coil-Near-Plug (CNP) ignitions (one coil per plug with a short plug wire between the ...
ASE P2 TEST PRIMER: Fuel Systems
Multiport Fuel Injection (MFI) systems have one fuel injector for each of the engine's cylinders and spray fuel into the intake port in the cylinder head. Newer engines with ultra high-pressure "Gasoline Direct Injection" (GDI) spray fuel directly in...
ASE P2 TEST PRIMER: Battery, Charging and Starting Systems
The battery stores energy to provide starting and reserve power for the electrical system. Lead-acid batteries must be maintained at or near full charge for maximum life (average life is 4 to 5 years).
Why Auto Parts And Paint Mix Like Water And Oil
We focus all of our efforts in the areas that are making us the most amount of money, and paint is not that area.
