Belts and hoses are essential for the proper operation of various engine components, such as the alternator, water pump, and power steering pump. Over time, belts and hoses can crack, fray, and leak, leading to engine damage and breakdowns. Inspecting belts and hoses is an important part of a car tune-up.

During a belt and hose inspection, technicians will check the following:

Belts: Technicians inspect belts for cracks, fraying, and proper tension. They also check the belt’s alignment to ensure it is running smoothly.
Hoses: Technicians inspect hoses for cracks, leaks, and swelling. They also check the hose clamps to ensure they are tight and secure.

2.5. Fuel Pump Inspection

The fuel pump delivers fuel from the fuel tank to the engine. A malfunctioning fuel pump can lead to hard starts, rough idling, and decreased engine power. Inspecting the fuel pump is an important part of a car tune-up.

During a fuel pump inspection, technicians will check the following:

Fuel Pressure: Technicians measure the fuel pressure to ensure it is within the specified range.
Fuel Pump Relay: Technicians test the fuel pump relay to ensure it is functioning properly.
Fuel Filter: Technicians inspect the fuel filter for clogs and replace it if necessary.

2.6. Fluid Level Check

Maintaining proper fluid levels is essential for the proper operation of your vehicle. During a car tune-up, technicians will check the following fluid levels:

Engine Oil: Technicians check the engine oil level and condition. They will also recommend an oil change if necessary.
Coolant: Technicians check the coolant level and condition. They will also check for leaks in the cooling system.
Brake Fluid: Technicians check the brake fluid level and condition. They will also check for leaks in the brake system.
Power Steering Fluid: Technicians check the power steering fluid level and condition. They will also check for leaks in the power steering system.
Transmission Fluid: Technicians check the transmission fluid level and condition. They may also recommend a transmission fluid flush if necessary.

3. How Often Should You Get A Tune-Up?

In the past, it was common practice to schedule car tune-ups every 12,000 miles. However, modern vehicles are designed to go much longer between tune-ups. Many manufacturers now recommend tune-ups, primarily spark plug replacement, at 100,000-mile intervals.

To determine the recommended tune-up interval for your vehicle, consult your vehicle’s owner’s manual. If you cannot locate your owner’s manual, CARS.EDU.VN can help. Our technicians can locate your vehicle information and provide you with the recommended tune-up schedule.
