Engine Options:
The Alfa Romeo 75 was renowned for its range of Twin Cam inline-four and Busso V6 engines. Common variants include 1.6, 1.8, 2.0 Twin Cam, 2.0 Turbo, 2.5 V6, and 3.0 V6.
2.0 Twin Cam Performance:
Approx. 120 hp (89 kW), 170 Nm torque
2.5 V6 Performance:
Approx. 158 hp (118 kW), 206 Nm torque
3.0 V6 Performance:
Approx. 192 hp (143 kW), 245 Nm torque
Fuel Delivery:
Carbureted (e.g., Weber, Solex) on earlier Twin Cam models, Bosch L-Jetronic or Motronic fuel injection on later Twin Cam and all V6 models.
Engine Layout:
Inline-4 and V6 configurations
Coolant Type:
Ethylene Glycol based coolant (typically a 50/50 mix with distilled water)
Oil Change Interval:
Typically every 10,000 km (6,000 miles) or annually. Refer to manual for specific engine type and oil specification.
Timing Belt Interval:
Crucial for Twin Cam engines; typically 60,000 km (37,000 miles) or 5 years. Belt failure can cause catastrophic engine damage. V6 engines often use a timing chain or different belt intervals.
Engine Oil Specification:
Varies by engine. Typically API SG/SH or higher, with viscosities like 10W-40 or 15W-50. Check manual for exact recommendation.
Brake Fluid Specification:
DOT 3 or DOT 4
Common Problems:
Rust (especially around wheel arches, sills, and door bottoms), electrical gremlins (wiring degradation), cooling system issues (radiator leaks, hose degradation), wear on suspension bushings, potential clutch master/slave cylinder issues, carburetor tuning on older models.
Part Replacements:
Ignition components (spark plugs, leads), fuel filters, air filters, brake pads/discs, exhaust system components, clutch components, suspension arms and bushings.
