The timing belt is an important component of the car's engine, and its failure can cause serious damage. This belt synchronizes the camshaft and the crankshaft, and if it becomes desynchronized, collisions can occur between the valves and the pistons, resulting in significant harm. Therefore, it is important to replace the timing belt at the recommended mileage specified by the manufacturer to prevent serious damage and avoid the need for an engine overhaul.

The oil and filter change in automatic and manual transmissions is recommended at intervals that are specific to the particular vehicle and manufacturer. Typically, these intervals range between 50,000 and 100,000 kilometers, but there may be variations depending on usage conditions and the type of transmission. It is important to check the owner's manual or consult a service center to get precise instructions for oil and filter change in your vehicle's transmission. Regular oil and filter changes ensure optimal performance and longevity of the transmission.

The change of oil in the differential and transfer case is usually recommended at specific intervals by the vehicle manufacturer or the manufacturer of the respective component. Typically, these intervals range between 30,000 and 50,000 kilometers or every 2 to 4 years, depending on the usage conditions and the vehicle's load. However, it is important to check the owner's manual or consult the service center to ensure the accurate intervals for oil change in the differential and transfer case of your vehicle. Regular oil changes ensure optimal performance of these systems and help prevent damage and wear.

The replacement of brake fluid is recommended to be done every 2 years. This is necessary because brake fluid absorbs moisture from the air over time, which can reduce the effectiveness of the braking system and cause issues during braking. Regular replacement of brake fluid ensures reliable brake operation and enhances the safety of the vehicle.

Coolant replacement is usually recommended every 2 to 5 years, depending on the type of coolant and manufacturer's recommendations. However, the exact intervals may vary depending on the specific vehicle and usage conditions. Coolant plays a vital role in engine cooling and provides protection against freezing and corrosion. Regular coolant replacement is necessary to maintain optimal cooling system performance and prevent potential engine damage.
