Lever the lid off with a screwdriver at this point only: levering anywhere else could crack the plastic. Do not overtighten the screws when refitting.
Take the element out and look at it. If the cleaner has a side spout the element will be dirty on one side. If it is not obviously dirty and clogged, turn it so that the cleanest section is opposite the intake hole and refit it.
If the element is dirty all over, fit a new one.
A new air-filter element must be the right type and size for your car. Consult your car handbook for the correct type. Different elements let varying amounts of air through. However, the new element may look different from the old one. Some are supplied folded, and have to be pulled out into shape.
To clean a wire-gauze filter, take the cleaner off and remove the top of the casing. Lift out the gauze element. Wash it and the casing thoroughly in petrol.
Generally the element is meant to be lightly oiled; consult the car handbook. If so, dip it in engine oil and stand it on a tray to drain. Refit the element and the cleaner.
Removing and refitting the cleaner body
On some carburettors there is a central bolt from the carburettor through the air cleaner and into its lid. Take the nut off the bolt to remove either the lid or the whole cleaner. Unclip any breather hose connected to the cleaner.
There is a rubber gasket on a flange on the intake stub of the carburettor. Refit it the right way round: there are often holes in the flange which must not be blocked.
Another, older system has a rubber seal and clamp. Unscrew the clamp to free the cleaner. To refit, place the seal squarely around the intake stub. Slide on the cleaner and tighten the clamp.
Do not overtighten the clamp or you may force the seal off so that it falls into the carburettor. If the seal is swollen with age and no longer fits, change it.
Weber twin-choke and some Solex carburettors often have an air cleaner held on by studs with nuts. These are either self-locking nuts or have locking tab washers underneath. They must lock properly: do not let one fall into the carburettor - it may be sucked into the engine and cause a lot of damage.
Reuse locking tabs only if there is an unbent corner left to fold up.
Sometimes the cleaner sits on two brackets fixed to the engine. Pins on the cleaner fit into rubber or plastic rings set in holes in the brackets. Lever the pins out with a broad screwdriver.
If a ring comes out of the hole, push it back. Grease the pin lightly when refitting. Replace any damaged ring.
Turn a circular air cleaner with a spout so that it draws warm air from near the exhaust manifold in winter, and cool air from an open space in summer. Before twisting it, slacken retaining nuts or clips.
Instead, it may have a flap valve inside, with a control marked 'summer-winter' or with sun and snowflake symbols.
If it has neither arrangement, there is probably an automatic heat-sensing flap inside the air intake. If you can see this, check that it opens when the engine has warmed up fully on a warm day.
