  Q: How to replace the Mass Air Flow Sensor/intake air temperature sensor on GMC Sierra 3500 Classic?

  A: The replacement process of the Mass Air Flow Sensor/intake Air Temperature Sensor requires gentle handling of the Mass Air Flow Sensor/iat sensor to protect its honeycell area but you need to avoid all contact with cleaning solutions and lubricants near its sensing elements while minimizing lubricant application only on the air duct. You should first disconnect the air cleaner outlet resonator before separating the engine wiring harness electrical connector from the Mass Air Flow Sensor/iat sensor. You should first use a screwdriver to get rid of the Mass Air Flow Sensor/iat sensor adapter clamp before taking the sensor off its position on the air cleaner assembly. The Mass Air Flow Sensor/iat sensor must receive placement with its embossed arrow facing toward the engine before installation into the air cleaner assembly and subsequent closure of the adapter clamp using 4 n.m of pressure (35 lb in). Safely install the air cleaner outlet resonator after reattaching the engine wiring harness electrical connector to the Mass Air Flow Sensor/iat sensor.
