The Saab B230FIZAA is a 2,290 cc, inline‑five naturally aspirated petrol engine produced between 1994 and 1998. It features a cast iron block, aluminium head, single overhead camshaft (SOHC), and Bosch LH2.4 Jetronic fuel injection. This engine was designed for durability and smooth power delivery in Saab's premium sedans and wagons.
Fitted primarily to the 9000 CS and 9000 CD models, the B230FIZAA was engineered for refined highway cruising and dependable daily use. Emissions compliance for its production period was met through its electronic fuel injection and catalytic converter, allowing it to meet Euro 1 standards in most European markets.
One documented concern is oil sludge buildup in the cylinder head, particularly in vehicles with irregular maintenance schedules. This issue, referenced in Saab Technical Service Bulletin TSB-95-08-01, is often linked to infrequent oil changes and extended warm-up cycles in cold climates. Later production runs saw minor revisions to the PCV system to mitigate this concern.
Production years 1994–1998 meet Euro 1 standards (EU Directive 91/441/EEC).
The Saab B230FIZAA is a 2,290 cc inline‑five naturally aspirated petrol engine engineered for premium sedans (1994-1998). It combines SOHC valvetrain with Bosch LH2.4 fuel injection to deliver smooth, linear power delivery. Designed to meet Euro 1 emissions standards, it prioritizes reliability and refined operation.

The SOHC design provides robust, low-maintenance operation but requires strict 10,000 km oil changes to prevent sludge accumulation in the head. Using the specified 10W-40 oil is critical for maintaining proper lubrication under the engine's thermal loads. The Bosch LH2.4 system is generally reliable but sensitive to poor electrical grounds and aged sensors. The chain-driven timing system is durable but should be inspected for tensioner wear at 150,000 km. PCV system maintenance is crucial to prevent crankcase pressure buildup and subsequent oil leaks.
Oil Specs: Requires SAE 10W-40 meeting API SH/CD specification (Saab Owner's Manual 9000).
Emissions: Euro 1 certification applies to all 1994–1998 models (EU Directive 91/441/EEC).
Power Ratings: Measured under DIN 70020 standards (Saab Group PT‑1996).

The Saab B230FIZAA was used exclusively across Saab's 9000 platform with longitudinal mounting and no licensed applications. This engine received minor platform-specific adaptations-different engine mounts for the CS (hatchback) and CD (sedan) variants-and no significant facelift revisions occurred during its production run. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat pad on the front of the cylinder block, just below the exhaust manifold (Saab Workshop Manual 9000). The code 'B230FIZAA' will be clearly visible. Visually, it can be identified by its inline-five configuration, single cam cover, and Bosch LH2.4 fuel injection components (airflow meter, ECU). It is distinct from turbocharged B230 variants by the absence of a turbocharger and associated plumbing. Engine mounts differ between CS and CD models; parts are not interchangeable without modification.
The B230FIZAA's primary reliability risk is oil sludge accumulation in the cylinder head, with elevated incidence in vehicles subjected to short trips or infrequent oil changes. Saab TSB-95-08-01 documents this issue, while owner club data suggests it is the leading cause of premature top-end wear. Neglecting oil changes and PCV system maintenance makes adherence to the 10,000 km service interval critical.
