Second Hand Ford Sierra Intercooler

Only one variant of the Ford Sierra was ever fitted with an intercooler: the Sierra RS Cosworth, which used a turbocharged 2.0 Pinto-derived YBB engine and had an intercooler as a core part of its forced-induction system. All other Sierra engines — the 1.3, 1.6, 1.8, 2.0 OHC, 2.3 V6, 2.8 V6, and 2.9 V6 — are naturally aspirated and never had an intercooler fitted from the factory. If you own a standard Sierra and are searching for an intercooler, it is worth double-checking you have the right model, as you may be looking for a different cooling component such as the radiator or oil cooler.

The Sierra RS Cosworth ran from 1986 through to the end of Sierra production in 1992 and went through revision cycles, including the move to the Sapphire bodystyle in 1988 and a four-wheel-drive variant from 1990, and mounting points, pipework, and ancillary routing can differ across these versions. The engine code is your most important starting point, but whether the intercooler and its associated pipework interchange directly across these production changes is something you should confirm with the breaker against your exact registration. Supplying your VIN or registration to the breaker will allow them to cross-reference the specific intercooler and mounting configuration your car left the factory with.

Trim level has no bearing on intercooler fitment — the intercooler is an engine-driven mechanical component and the same unit was used regardless of interior specification. Body style is worth mentioning to the breaker as context, since the three-door hatchback Cosworth and the four-door Sapphire Cosworth represent different production phases and may have had ancillary differences, but the intercooler core itself follows the engine code rather than the body. Always confirm the full engine code with the breaker to make sure you are getting the correct unit for your car.

No — the standard 2.0 OHC engine fitted to the mainstream Sierra range is naturally aspirated and has no turbocharger, so there is no intercooler on that vehicle. If you are experiencing cooling or overheating issues on a 2.0i Sierra, the parts you are more likely to need are the radiator, thermostat, or coolant hoses. A breaker who specialises in Sierras will be able to point you toward the right component once you describe your symptoms.

The single most useful piece of information is the engine code, which you can find on your V5C or by running a VIN check — this tells the breaker exactly which turbocharged variant you have and helps them match the correct intercooler and associated pipework. You should also tell them whether you have the two-wheel-drive or four-wheel-drive Cosworth, as drivetrain layout can influence ancillary and mounting configurations. Year of manufacture and the full registration will further help the breaker confirm fitment, and they may ask to check specific details against your car before guaranteeing the part will fit.
