Renault 12 Replacement Engines
The Renault 12 evolved through several critical generations from 1969 to 1980, with the original 1.3L Cléon engine family (1969-1976) followed by the updated 1.4L and 1.6L variants (1976-1980). All early Cléon engines (1390cc) suffered from timing chain tensioner failures and head gasket issues, while later fuel-injected models (1978-1980) experienced carburettor linkage problems and fuel pump failures. The 1.6L diesel variants introduced in 1979 shared identical injection pump vulnerabilities across all trim levels. Renault Service Bulletins addressed timing chain guides and cooling system modifications that applied to entire generation families rather than individual variants.
Renault 12 Models & Engines Codes
The Renault 12 engine families span multiple generations with shared components and common failure patterns across variants.
- Cléon-1390: 1.3L petrol (1969-1976) - Timing chain tensioner failure across all variants
- Cléon-1400: 1.4L petrol (1976-1980) - Head gasket issues in all 12 models
- Cléon-1600: 1.6L petrol (1976-1980) - Carburettor linkage problems across trim levels

- Fuel Injection: Late 12 models (1978-1980) - Fuel pump and carburettor issues
All Cléon engines share identical timing chain components and cooling system architecture, meaning failures affect entire generation families rather than individual models.
