Chevrolet Mai Rui Bao air filter is located in the engine compartment. Replace Mai Rui Bao air filter element: Remove the cable of the hood locking mechanism from the buckle, and loosen the intake pipe self-locking clip with a straight knife. Disconnect the plug of the air flow meter. Please note that there is a lock button on the back of the plug. Press hard and pull out the plug. Then, remove the air intake box as a whole. Loosen the clip of the cover plate of the air intake box. Open the air intake box and you can see the empty air filter element. Check the old filter element and clean the gas collection box. Just install a new filter element in the opposite direction. Maintenance of Maibao dry inertial filter: Dry inertial air filter consists of dust cover, deflector, dust outlet and dust cup. Pay attention to: 1 during maintenance. Check and clean the dust hole on the cover of centrifugal dust collector frequently, remove the dust adhered to the guide vane, and pour the dust into the dust collecting cup (the amount of dust collected in the container shall not exceed 1/3 of its volume). When installing, ensure the tightness of the rubber gasket at the joint, and there shall be no air leakage; Otherwise, it will cause short circuit of air flow, reduce the speed of air and greatly reduce the dust removal effect. 2. Dust removal hood and diversion device should keep the correct shape. If there are bumps, they should be reshaped in time to avoid changing the flow direction of the original design and reducing the filtering effect. Some drivers are not allowed to refuel the dust cup (or the tray of the vacuum cleaner). Because oil is easy to splash on the dust outlet, guide vane and other parts, this part will absorb dust, which will eventually reduce the filtration and separation ability.
