This document is a guide to the vehicle identification numbers of Jaguar cars. It lists the locations of the chassis number, engine number, body number, and gearbox number for different models of Jaguar cars.
Research Guide No. 002, issued by the Jaguar Daimler Heritage Trust in September 2022, is a vehicle numbers locator guide. It lists where chassis, engine, body and gearbox numbers are located on models covered in the guide, from Standard Swallow and Wolseley Hornet Swallow through SS and SS Jaguar cars to Jaguar Mark IV, Mark V, XK 120, Mark VII, C-type, D-type, XKSS, XK 140, Mark I, XK 150 and Mark VIII.
The guide is arranged by model, with separate columns for chassis, engine, body and gearbox number locations. Entries describe stampings on chassis frames, cylinder blocks and gearbox casings, as well as plates and tags fitted to bulkheads, scuttles and other body areas; some entries include 1960s notes.
It is at the top/front of the left-hand side chassis member adjacent to the rear engine mounting, and sometimes also in the front cross member below the radiator.
The engine number is stamped in the raised boss cast on the block on the offside, just by the bulkhead.
It is on a small rectangular aluminium plate with large raised reverse-embossed numbers, fitted on the offside of the bulkhead.
It is typically on the left-hand side of the gearbox casing and on the top lid of the gearbox, and may only be seen if the gearbox is out of the car.
