Keeping a printed checklist in the workshop — codes, fluids, cooling, coding, road test — turns a stressful week into a predictable process your customers will remember positively.

Before any payment leaves your account, align three facts: the stamped engine code on the block, the donor VIN paperwork, and the emissions class required where the vehicle will be registered.

Low-mileage stock moves quickly in spring and autumn when seasonal demand peaks; securing the correct code early is often cheaper than accepting a near-match that requires extra coding hours.
