The Porsche 924 (1976–1988) was Porsche's front-engine, water-cooled entry-level sports car, notable for departing from Porsche's traditional air-cooled rear-engine layout. The 1981 Porsche 924 factory service manual documents the specific front-mounted four-cylinder engine for this model year.
Front-Engine Water-Cooled Service
The 924's front-mounted four-cylinder requires the correct oil specification and timing belt service interval documented in the factory manual — a critical service item given the engine's age, along with the manual or automatic transmission fluid specification and the transaxle-mounted rear differential fluid service.
