- Before installing or replacing the filter, turn off the engine and allow it to cool completely to prevent burns or other injuries. - Wear gloves and eye protection during operation to prevent dust, oil, or debris from coming into contact with your skin.

and eyes. - Only use filters that match your vehicle's make, model, and OEM specifications. Using incorrect filters can damage the engine or affect vehicle performance. - Dispose of used filters according to local environmental regulations.

regulations. Do not dispose of them randomly to avoid environmental pollution. 2. Product Introduction This car filter is designed to effectively filter impurities such as dust, sand, metal particles, and oil residue present in air, oil, or fuel.

system, protect the engine and related components, extend the vehicle's service life, and ensure stable operation. Applicable Filter Types: Air Filter, Oil Filter, Fuel Filter (please confirm the specific type based on the

product model).
3. Installation Steps 3.1 Air Filter Installation
1. Locate the air filter housing in the engine compartment. This is usually a rectangular or cylindrical plastic or metal case, secured with clips or bolts.
2. Loosen the clips or remove the bolts to open the housing cover.
3. Remove the old air filter and clean the inside of the housing with a clean cloth to remove accumulated dust and debris.
4. Properly install the new air filter into the housing, ensuring it fits snugly and is not tilted (if present, follow the direction mark on the filter).
5. Close the housing cover and securely fasten the clips or bolts to prevent air leaks. 3.2 Oil Filter Installation
1. Park the vehicle on a level surface and engage the handbrake. Jack up the vehicle if necessary for easy access to the oil filter.
2. Completely drain the engine oil according to the vehicle's service manual, then use an oil filter wrench to remove the old oil filter.
3. Clean the filter mounting surface on the engine to remove any residual oil and debris, ensuring no dirt remains.
4. Apply a thin layer of new engine oil to the rubber gasket of the new oil filter to ensure a tight seal.
5. Install the new oil filter by hand, rotating it clockwise until the gasket contacts the mounting surface, then tighten it slightly with an oil filter wrench (do not overtighten to avoid damaging the gasket).
6. Fill the engine with new oil according to the specified capacity, then start the engine and check for any oil leaks around the filter. 3.3 Fuel Filter Installation
1. First, bleed the fuel system pressure (consult the vehicle's service manual for specific methods) to prevent fuel spray during installation.
2. Locate the fuel filter (usually near the fuel tank or in the engine compartment) and disconnect the fuel lines on both sides of the filter (note the fuel flow direction to avoid reverse installation).
3. Remove the old fuel filter from its mount and install the new fuel filter, ensuring the flow arrow on the filter is correctly oriented
to the fuel flow direction.
4. Reconnect the fuel lines securely, ensuring there are no looseness or leaks.
5. Start the engine and check for any fuel leaks at the filter connections. If there are no leaks, the installation is complete.
4. Maintenance and Replacement Cycle - Air Filter: Replace every 10,000-15,000 kilometers or every 12 months (whichever comes first). When driving in dusty or harsh environments, shorten the replacement cycle appropriately. - Oil Filter: Replace

every 5,000-7,500 kilometers or at every engine oil change (whichever occurs first). - Fuel Filter: Replace every 30,000-40,000 kilometers or every 24 months (whichever occurs first). For diesel vehicles, shorten the cycle based on fuel

quality.
5. Troubleshooting - If the engine vibrates abnormally or power decreases after installation: Check if the filter is installed correctly, if it is tilted or not properly secured, and replace it with a suitable filter if necessary.

- Oil or fuel leakage: Check if the filter gasket is damaged or not properly tightened, and reinstall or replace the gasket/filter. - Excessive fuel consumption or poor acceleration: Check if the fuel filter is clogged and replace it in

time.
