How Do You Change a Smog Pump?

A smog pump, also called an air injection pump, is a device that forces fresh air into the exhaust system of a vehicle to help reduce pollution. The smog pump is usually located near the front of the engine and is driven by a belt from the engine. To change a smog pump, first identify the type of smog pump your vehicle has.

There are two common types: mechanical and electrical. Once you know which type you have, follow these steps: For a mechanical smog pump:

1) Disconnect the negative battery cable to prevent electrocution. 2) Remove the drive belt from the pulley on the front of the smog pump. This will require loosening or removing other belts in some cases.

3) Unbolt the smog pump from its mounting bracket using a wrench or socket set. Some pumps may have additional bolts holding them in place; remove these as well. 4) Pull the old smog pump out of its mount and discard it.

If necessary, clean up any debris left behind before installing the new one.
