Engine Options 1984 1988:
Various 4-cylinder and 6-cylinder gasoline and diesel engines. Common gasoline engines include the M102 (2.3L, 2.3-16) and M103 (2.6L). Diesel engines include the OM601 (2.0L D, 2.0L TD) and OM602 (2.5L TD).
Typical Horsepower Range:
Ranges from approximately 70 hp for diesel models to over 180 hp for the 2.3-16 Cosworth variant.
Typical Torque Range:
Ranges from approximately 100 lb-ft for diesel models to over 170 lb-ft for performance variants.
Injection Systems:
Bosch K-Jetronic mechanical fuel injection for many gasoline models; Weber carburetors on some very early or specific variants. Diesel models feature Bosch inline or rotary injection pumps.
Fuel Type:
Unleaded gasoline (typically 91-95 RON) for gasoline engines; Diesel fuel for diesel engines.
Valve Adjustment Interval:
Recommended every 30,000-40,000 miles or as specified by engine type (e.g., hydraulic lifters vs. shims).
Wheelbase:
Approx. 2619 mm (103.1 in)
Length:
Approx. 4350-4420 mm (171.3-174.0 in)
Width:
Approx. 1690-1710 mm (66.5-67.3 in)
Height:
Approx. 1370-1380 mm (53.9-54.3 in)
Curb Weight:
Varies by engine and equipment, typically ranging from 1200 kg to 1400 kg (2645 lbs to 3086 lbs).
Gross Vehicle Weight Rating:
Typically around 1700 kg to 1800 kg (3748 lbs to 3968 lbs).
Crash Test Performance:
While specific contemporary ratings are scarce by modern standards, the W201 was known for its robust body structure and safety engineering for its era, exceeding many competitors.
ABS:
Anti-lock Braking System (ABS) was an optional or standard feature on higher trims and later models.
Traction Control:
ASR (Anti-Slip Regulation) was introduced later in the W201's lifecycle and may be present on some 1988 models.
Seatbelts:
Three-point inertia-reel seatbelts were standard, with pretensioners becoming available on later models.
Driver Airbag:
Driver's side airbag was optional on some models, and standard on later production years or specific markets.
Oil Change Interval:
Typically every 5,000 to 7,500 miles (8,000 to 12,000 km) or annually, depending on driving conditions and oil quality.
Coolant Flush Interval:
Every 2-3 years or as specified for the particular coolant type (e.g., Mercedes-spec coolant).
Brake Fluid Flush Interval:
Typically every 2 years due to hygroscopic nature of brake fluid.
Engine Oil Specification:
API SG or higher, MB-Approval 229.1 for gasoline engines (e.g., SAE 10W-40, 15W-40, or 5W-40 depending on climate). Consult manual for specific engine recommendations.
Coolant Specification:
Mercedes-Benz specification coolant (e.g., G05 or equivalent glycol-based coolant with corrosion inhibitors, mixed 50/50 with distilled water).
Power Steering Fluid:
Typically specified as Pentosin CHF 11S or MB spec 236.3, or a compatible hydraulic fluid.
Common Issues Engine:
Valve cover gasket leaks, timing chain tensioner failure (on some early M102/M103 engines), fuel distributor issues (K-Jetronic), and vacuum hose degradation.
Common Issues Chassis:
Worn suspension bushings (especially front lower control arm bushings), sagging headliner, and potential for rust in common areas like wheel wells and sills.
Common Issues Electrical:
Fraying wiring harnesses (especially around engine bay), instrument cluster failures, and climate control module issues.
Mercedes Benz Philosophy:
The 190 (W201) was Mercedes-Benz's entry into the compact executive sedan segment, built with the brand's signature quality, durability, and engineering excellence.
Introduction Year:
Introduced in 1982 globally, with the 1984-1988 range covering the initial and mid-lifecycle updates.
Key Variants:
Included base models, diesel variants (190D), and performance-oriented models like the 190E 2.3-16 and 190E 2.5-16 (Cosworth).
Production Period:
1982-1993 (this manual covers a significant portion of its production life).
Manufacturing Locations:
Primarily Germany, with some production also occurring in South Africa and other facilities.
