As a vehicle owner, you must have the moral obligation to help reduce the emission of harmful exhaust gases to the environment. The air that you breathe might be contaminated and you may be slowly killing yourself. There are different types of devices that can reduce the harmful gases coming out of your auto, and one that you can install is the Dorman air pump. This typical mechanical device consists of a network of hoses and tubes. This is a belt-driven air pump with air management valves. It is an emission add-on installed by many automakers to help clean up emissions. It supplies air to the exhaust stream to promote additional burning of the gases such as hydrocarbons and carbon monoxide. It can further reduce oxides of nitrogen which is a major contributor to photochemical smog. This part requires little maintenance but you should not ignore its existence in your auto. From time to time, the air pump belt should be inspected so that it will be in good condition and correctly tensioned. The symptom of a malfunctioning air pump is a failed emission test, backfiring in the exhaust, and an overheating catalytic converter. To avoid wrong diagnosis of the failure, it is wise to seek the assistance of a professional technician to pinpoint the real cause. Should the recommendation be to replace the air pump, never hesitate to get one in our online store. Before you place your order, you can talk to our sales agents to help you.
