Peugeot 504 Replacement Engines
The Peugeot 504 evolved through three key generations from 1968-1988, with petrol and diesel engines sharing common architecture across saloon, estate, and pickup variants. The X6D diesel family (1.9L) suffered head gasket failures addressed in Peugeot Service Bulletin 74-03, while XU9 petrol engines (2.0L) required timing belt replacement at 60,000 miles regardless of body style. All 504 engines used identical mounting systems and shared oil pump components, with X6D units particularly prone to oil pressure issues that affected both saloon and estate models equally.
Peugeot 504 Models & Engines Codes
The 504 series utilized two primary engine families across all body styles, with specific variants sharing identical components and failure patterns. Engine codes remained consistent across saloon, estate, and pickup models throughout production years.
- X6D: 1.9L diesel (1979-1984) - Head gasket failures across all 504 variants
- XU9: 2.0L petrol (1979-1985) - Timing belt issues in all 504 body styles
- X6TA: 1.9L turbo diesel (1982-1988) - Turbocharger problems in 504 models
- XU5: 1.4L petrol (1974-1980) - Carburetor issues across early 504 range
- XU8: 1.8L petrol (1977-1983) - Camshaft wear in all 504 petrol variants
All 504 engines used identical mounting configurations regardless of body style, meaning X6D components from saloons fit estates and pickups. The shared architecture means failure patterns affected all 504 variants equally, with head gasket issues in X6D units occurring across the entire model range.
