Engine Family:
Fiat Tipo 1990 offered a range of engines, including FIRE, Lampredi, and possibly PSA-derived units depending on market. The manual would cover common variants.
Engine Variants Covered:
Likely includes 1.1L FIRE, 1.4L FIRE, 1.6L FIRE, 1.7L Diesel, 1.8L Lampredi (e.g., 159A.000), and potentially 2.0L (e.g., 160A.000) for performance variants like the Tipo DGT.
Horsepower Range:
Approx. 56 hp (1.1L) to 138 hp (2.0L 16V).
Torque Range:
Varies significantly with engine size.
Injection Type:
Electronic Fuel Injection (EFI), typically Bosch LE2-Jetronic or similar single-point/multi-point systems.
Fuel Type:
Unleaded Gasoline (Petrol), Diesel for diesel variants.
ECU Coverage:
Information on Engine Control Unit (ECU) operation, sensor inputs, and actuator outputs for fuel and ignition management.
Oil Change:
Typically every 10,000-15,000 km or 6-12 months, depending on driving conditions and oil type used.
Timing Belt:
Crucial for FIRE and Lampredi engines. Typically replaced every 60,000-80,000 km or 4-5 years, as failure can cause severe engine damage.
Engine Oil:
API SG/SH or ACEA A2/A3 rated. Viscosity grade would typically be 10W-40 or 15W-40, consult specific engine variant for exact recommendation.
Coolant:
Ethylene glycol-based antifreeze. Mixture of 50% coolant and 50% distilled water is standard. Specific Fiat coolant type would be detailed.
Brake Fluid:
DOT 3 or DOT 4.
Rust:
Common for vehicles of this era, especially in wheel arches, sills, and around windows.
Electrical Gremlins:
Can experience issues with wiring harnesses, sensors, and dashboard components due to age and materials.
Engine Management:
Issues with fuel injectors, ignition coils, and sensors related to the EFI system can arise.
