• Serpentine Belt: This is a single, long belt that drives multiple engine components, such as the alternator, power steering pump, and air conditioning compressor. Over time, serpentine belts can wear, crack, or become damaged, leading to a loss of power to essential systems.

​

• Timing Belt (if applicable): Some vehicles have a timing belt that synchronizes the rotation of the engine's camshaft and crankshaft. Timing belt replacement is crucial to prevent engine damage in case of failure.

Drive Belts:

• Radiator Hoses: These hoses carry coolant between the engine and the radiator. Over time, they can deteriorate, crack, or develop leaks, leading to cooling system problems and potential engine overheating.

​

• Heater Hoses: Heater hoses circulate coolant to the vehicle's heater core, providing warmth to the interior. Like radiator hoses, they can degrade over time and may need replacement.

​

• Power Steering Hoses (if applicable): In vehicles equipped with power steering systems, hoses carry power steering fluid between the pump and steering components. Damaged or leaking hoses can result in power steering issues.

​

• Vacuum Hoses: These hoses play a role in various engine functions, such as controlling emissions and operating components like the brake booster. Cracked or damaged vacuum hoses can lead to poor engine performance.

Hoses:

• This involves measuring the levels of pollutants in the vehicle's exhaust gases. Technicians assess whether the vehicle complies with emission standards and whether there are issues with the combustion process.

Air Conditioning (A/C) Belt (if applicable):

• During a belt and hose replacement service, technicians inspect these components for signs of wear, cracking, fraying, or other damage. If any issues are identified, the belts or hoses are replaced to ensure continued reliability.

Inspection and Replacement:

• Some belts require proper tension for optimal performance. Technicians may adjust the tension of certain belts during the replacement process.

• Tension Adjustment (if applicable):
