3. Manutenzione ordinaria
Regular maintenance is crucial for the longevity and performance of your Fiat Punto. This section outlines routine checks and service procedures that should be performed at specified intervals.
3.1 Engine Oil and Filter Change
- Warm the engine to operating temperature, then switch off and allow to cool slightly.
- Position a drain pan beneath the sump plug.
- Remove the sump plug and allow the old oil to drain completely.
- Remove the old oil filter using a suitable filter wrench.
- Apply a thin film of new oil to the rubber seal of the new filter, then screw it on by hand until snug. Tighten an additional half to three-quarters turn.
- Refit the sump plug with a new washer and tighten to the specified torque.
- Rabboccare il motore con il tipo e la quantità di olio motore nuovo consigliati.
- Start the engine and check for leaks. Allow to run for a few minutes, then switch off and recheck the oil level after a short period.
3.2 Fluid Level Checks
- Refrigerante: Check the coolant level in the expansion tank when the engine is cold. Top up with the specified coolant mixture if necessary.
- Liquido freni: Ensure the brake fluid level is between the MIN and MAX marks on the reservoir. A low level may indicate worn brake pads or a leak.
- Liquido del servosterzo: Check the power steering fluid level with the engine off and cold.
- Windscreen Washer Fluid: Keep the reservoir topped up for clear visibility.
