The Ford York engine is an inline diesel engine manufactured by Ford used in vehicles including the Ford Transit range of vans between 1972 and 2000.
Applications
The Transit was fitted with a 2.5-litre four-cylinder engine, but the engine was also available as a 3.5-litre six-cylinder engine. These were fitted in the Ford A series of light commercial vehicles. The York engine superseded the Perkins 4.108 IDI engine. The later 4-cylinder versions had more modern glowplugs as a cold start system.
Succession
The engine was redesigned in 1984 at a cost of £100 million, becoming the Ford 2.5 DI engine. The block shared the same cylinder spacing and bore, allowing production in the same facility and use of the improved block as a service part for the older engine. The front PTO was discontinued and replaced by a harmonically balanced crankshaft pulley to reduce engine noise. The 2.5 DI was launched in mainland Europe some months before being introduced in the United Kingdom, due to much greater demand for diesel engines in that market at the time.
