To find parts using the in TecDoc:
Many parts (like timing belts, water pumps, and gaskets) are "up to engine number X" or "from engine number Y." Searching by engine number eliminates the guesswork common in generic year/make/model searches.
In most TECDoc front-end software (like TecAlliance’s "TEC-Centric" or third-party DMS):
Most modern vehicles have a unique chassis number (VIN). While a VIN search is the gold standard for the entire vehicle, an engine number search is perfect when you are working with a rebuilt engine, a used engine from a different donor car, or when you need a part that is strictly tied to the engine's construction, like pistons, seals, or timing kits. The engine number is the final arbitrator of compatibility when vehicle model years overlap.
