ASE Practice Test (P2: Parts Specialist) 2

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?

Accepted Answer

Ask the customer to verify whether their vehicle has air conditioning before selecting the correct part number

Answer

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?

Accepted 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

Answer

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?

Accepted Answer

The engine's casting number and production date, as cylinder head specifications can vary within the same engine family

Answer

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?

Accepted Answer

A deposit charged at purchase that is refunded when the customer returns the old (core) part in rebuildable condition

Answer

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?

Accepted 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

Answer

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.
