The Saab 900 is a mid-sized automobile which was produced by Saab from 1978 until 1998 in two generations; the first from 1978 to 1993, and the second from 1994 to 1998.

The first-generation car was based on the Saab 99 chassis, though with a longer front end to meet U.S. frontal crash regulations and to make room for the turbo-charged engines, air conditioning and other equipment that was not available in the early days of the 99 model. The 900 was produced in 2- and 4-door sedan, and 3- and 5-door hatchback configurations and, from 1986, as a cabriolet (convertible) model. There were single- and twin-Zenith carburettor; fuel injected, and turbocharged engines, including both Full Pressure Turbo (FPT), and, in European models during the early 1990s, Low Pressure Turbos (LPT).

Saab 900 "Classic"

Overview

The Saab 900 is a front-engine, front-wheel-drive mid-size car with a longitudinally mounted, 45-degree canted, inline four-cylinder engine, double wishbone front suspension and beam-axle rear suspension. It was originally introduced on 12 May 1978, for the 1979 model year. Sales commenced in the fall of 1978.

Like its predecessor the 99, the 900 contained a number of unusual design features that distinguish it from most other cars. First, the B-engine, that was installed "backwards", with power delivered from the crank at the front of the car. Second, the transmission, technically a transaxle, bolted directly to the bottom of the engine to form the oil pan (albeit with separate oil lubrication). Thus, power from the crank would be delivered out of the engine at the front, then transferred down and back to the transmission below, via a set of chain-driven primary gears. In similar fashion, Minis also had their gearbox mounted directly below the engine; however, the Mini gearbox and engine shared the same oil, whereas the Saab 900 (and 99) gearboxes contained a separate sump for engine oil.

The 900 body was developed from the older 99 model, keeping the basic layout but with a new longer front part. This allowed for more space in the engine room and better crash protection for passengers. The middle and rear parts of the body were identical to the 99 Combi Coupé (which was withdrawn from the lineup at the same time). Later a new rear end was designed for the 2- and 4-door sedans.

Refined over several decades of two-digit Saab models, the 900's double wishbone suspension design provided excellent handling and road feel. The rear suspension comprised a typical beam axle design, stabilized with a Panhard rod. However, the attachment points between the axle and chassis made up an unusual configuration that, in essence, consists of two Watt's linkages at either end of the axle: A lower control arm attaches the axle to the bottom of the vehicle, while an upper link attaches at the top but faces towards the rear, unlike a typical four-link design with both lower and upper links facing forward. The design-principle being similar with the rear suspension presented in Alfa Romeo Alfasud already in 1971, except in the Alfasud, the beam axle itself functioned as a sway-bar, hence separate sway-bars in the rear suspension was not needed.

Early models did not have sway bars; they began appearing on certain models in 1985, and, in U.S. and possibly other markets, became standard on all trim levels by the late 1980s. The sway bars decreased body roll, but at the expense of some ride comfort and when driven aggressively, increased inside wheel spin. The front and rear bars' diameters were unchanged throughout the model's run.

The 900 has a deeply curved windshield, providing the best driver visibility. The dashboard was curved to enable easy reach of all controls, and featured gauges lit up from the front. Saab engineers placed all controls and gauges in the dashboard according to their frequency of use and/or importance so that the driver need only divert their gaze from the road for the shortest possible time and by the smallest angle. This is why, for example, the oft-used radio is placed so high in the dashboard. In keeping with the paradigm of its predecessor, the 99 model, the 900 employed a door design unique in automotive manufacturing, with an undercutting sweep to meet the undercarriage, forming a tight, solid unit when the door was closed. This feature also eliminated the stoop in the cabin at the footing of the door, as seen in automobiles of other manufacturers, thereby preventing water and debris from collecting and possibly entering the cabin or initiating corrosion, as well as enabling passengers to enter and exit the cabin without need to step over several inches of ledge.

The 900 underwent minor cosmetic design changes for 1987, including restyled front end and bumpers that went from a vertical to a more sloped design. To save money, Saab kept the basic undercarriage more or less unchanged throughout the 900's production run.

The Saab 900 could be ordered with different options, including a high performance option called the Aero or, as it was known in the U.S. "Special Performance Group" (SPG). The Aero/SPG incorporated (depending on the market and model year) a body skirt; a sport-suspension (1987+) that included shorter, stiffer springs, stiffer shocks, and sway bars; leather seats; premium stereo; and air conditioning. Each of these features could also be ordered independently from Saab's Accessories Catalog for fitment to standard models.

Another desirable UK option at this time was the fitment of very distinctive Minilite alloy wheels. Initially these had the words 'Minilite' and 'Saab' cast in raised lettering; later Saabs had a similar wheel made by Ronal.

Power output varied by model year and market, but 900S and 900 Turbo models produced from 1985 and onward were fitted with a 16-valve engine, while the basic 900 kept the earlier 8-valve engine.

A 1989 Saab 900 SPG, owned by Peter Gilbert of Wisconsin, was driven over a million miles before being donated to The Wisconsin Automotive Museum. Peter Gilbert claimed a million miles out of the turbocharging unit in addition to the engine itself. Saab gave Mr Gilbert a Saab 9-5 Aero.

Common 1989 Saab 900 problems

The Saab 900, produced in 1989, is known for several common problems that owners have reported over the years. These issues include front suspension problems, power steering rack failure, head gasket torque, and heater controls failure.

Front suspension problems are a common issue in the Saab 900. If you hear a knocking noise coming from the front suspension, it is usually caused by a faulty front suspension arm. This knocking noise will be most noticeable when driving over rough surfaces or speed bumps. To solve this problem, you will need to replace the front suspension arm.

Power steering rack failure is another common problem in the Saab 900. If you notice that the power steering on your Saab 900 is very stiff, particularly when you first start the car, it is a sign of a failing power steering rack. The stiffness may improve as you drive, but it is a sign that the power steering rack is failing. To resolve this issue, you will need to fit a replacement power steering rack.

Head gasket torque is also a common problem in the Saab 900. If the water reservoir tank that connects to the radiator seems to be under a lot of pressure, it is caused by the wrong torque on the head gasket stretch bolts. This problem can be seen from tear marks on the tank above the water line or other marks that suggest high pressure. To solve this problem, you will need to re-torque the head gasket stretch bolts to the correct specifications.

Heater controls failure is another common problem in the Saab 900. If one of the switches has snapped or one of the dials has come off on the heater controls, it is a sign of a failing heater control system. The switches are known to become tight and then snap, while the dials are known for losing directional control. If you have a problem with one of the heater control switches, it needs to be replaced, and if the dial has come off, you need to replace the faulty cable.

In addition to these common problems, the Saab 900 is also known for hard starting and stalling issues, which can be caused by a leaking fuel pressure regulator or other issues with the fuel system. These problems can be difficult to diagnose and may require the assistance of a professional mechanic.

In summary, the Saab 900 is known for several common problems, including front suspension problems, power steering rack failure, head gasket torque, and heater controls failure. These problems can be caused by a variety of factors and may require the assistance of a professional mechanic to diagnose and repair.
