General Information

Check condition and tension of air pump drive belt at least once every 12 months or 12,000 miles.
The air pump should not be disassembled for any reason, nor should it ever be clamped in a vise. Do not use a hammer or pry bar on pump housing. Do not lubricate the pump. The small hole on top of some pumps is not an oil hole. If the engine is to be steam cleaned, mask off the centrifugal filter fan to prevent liquids from entering the pump.
