ASE Practice Test (P2: Parts Specialist) 2 — Questions and Answers
Question 1: A customer requests a water pump for their vehicle. The parts specialist looks up the part and finds two listings for the same year/make/model — one for an engine with A/C and one without. What should the specialist do?
- Provide either part since they are probably the same
- Ask the customer to verify whether their vehicle has air conditioning before selecting the correct part number (Correct answer)
- Supply the less expensive option to save the customer money
- Order both parts and let the technician decide
Correct answer: Ask the customer to verify whether their vehicle has air conditioning before selecting the correct part number
Many parts vary based on vehicle configuration. Water pumps may differ because A/C-equipped vehicles route belts differently, requiring a different pump pulley arrangement. Providing the wrong part wastes the customer's time with a return trip. A good parts specialist always confirms application-specific details (engine size, A/C, transmission type, body style, country of manufacture date, etc.) before selecting from multiple catalog listings.
Question 2: What is a "hard part" in automotive parts terminology?
- A part made of steel as opposed to plastic
- A non-electrical mechanical component such as a water pump, brake caliper, or alternator — as opposed to a soft part like gaskets or filters (Correct answer)
- A part that is difficult to obtain from suppliers
- A component that requires special tools to install
Correct answer: A non-electrical mechanical component such as a water pump, brake caliper, or alternator — as opposed to a soft part like gaskets or filters
In the parts business, "hard parts" refers to major mechanical components — engines, transmissions, alternators, starters, water pumps, brake calipers, etc. "Soft parts" include gaskets, seals, filters, belts, and hoses. The distinction matters for pricing, core charges, and supplier sourcing. Hard parts typically carry core charges for exchange/remanufacturing programs.
Question 3: A technician orders a new cylinder head for an engine. The parts specialist should ask which additional critical detail before looking up the part?
- The vehicle's color
- The engine's casting number and production date, as cylinder head specifications can vary within the same engine family (Correct answer)
- Whether the customer wants painted or unpainted
- The vehicle's mileage
Correct answer: The engine's casting number and production date, as cylinder head specifications can vary within the same engine family
Engine casting numbers and production dates identify the specific version of an engine, which may have had design changes during production. Cylinder heads can vary within the same model year for the same engine displacement (different chamber volumes, valve sizes, port configurations, or gasket patterns). Using the casting number (found on the block or head itself) ensures the correct replacement head is selected for proper fit and performance.
Question 4: What is a "core charge" on a remanufactured part, and when is it refunded to the customer?
- A charge for the delivery of heavy parts to the store
- A deposit charged at purchase that is refunded when the customer returns the old (core) part in rebuildable condition (Correct answer)
- An additional warranty charge for extended coverage
- A restocking fee charged on returned parts
Correct answer: A deposit charged at purchase that is refunded when the customer returns the old (core) part in rebuildable condition
Remanufactured parts (alternators, starters, brake calipers, water pumps, etc.) require a supply of rebuildable old cores. The core charge is a deposit that ensures customers return their old part. When the customer returns the core in acceptable condition (not broken, missing pieces, or damaged beyond rebuild), the core deposit is fully refunded. This recycling system reduces manufacturing costs and environmental impact while keeping remanufactured part prices lower than new OEM.
Question 5: A customer is unsure which oil filter fits their vehicle. The parts specialist does not have the vehicle year/make/model memorized. What is the CORRECT method to find the right filter?
- Guess based on the filter size the customer describes
- Look up the vehicle in the parts catalog (electronic or print) using year, make, model, and engine size to retrieve the correct oil filter part number (Correct answer)
- Provide the most popular-selling filter and hope it fits
- Ask the technician in the shop to identify it by sight
Correct answer: Look up the vehicle in the parts catalog (electronic or print) using year, make, model, and engine size to retrieve the correct oil filter part number
Accurate parts identification requires using the vehicle's year, make, model, engine size (and sometimes sub-model or production date) in an automotive parts catalog. Electronic catalogs (such as NAPA, AutoZone, or OEM systems) cross-reference application data to the correct part number. Guessing or providing a part "that looks right" frequently results in returns, unhappy customers, and potential vehicle damage from an incorrect part.
Question 6: What does the abbreviation "OEM" mean in the parts business, and how does it differ from "aftermarket"?
- OEM stands for Optional Equipment Module; aftermarket means used parts only
- OEM (Original Equipment Manufacturer) parts are made by or for the vehicle manufacturer to exact original specifications; aftermarket parts are produced by independent manufacturers and may vary in specification (Correct answer)
- OEM parts are always less expensive than aftermarket
- OEM means remanufactured; aftermarket means new parts
Correct answer: OEM (Original Equipment Manufacturer) parts are made by or for the vehicle manufacturer to exact original specifications; aftermarket parts are produced by independent manufacturers and may vary in specification
OEM parts are manufactured by the same company that supplied the original component to the vehicle assembly line, or produced under license to meet original specifications. They are sold through dealerships and carry the vehicle brand warranty. Aftermarket parts are produced by independent manufacturers. Quality varies widely — some aftermarket parts match or exceed OEM quality while others are inferior. Understanding this distinction helps parts specialists and customers make informed purchasing decisions.
