2008 Chevrolet Express 3500 Parts Questions & Experts Answers

• Q: How to replace the Mass Air Flow Sensor/intake air temperature sensor on 2008 Chevrolet Express 3500?

  A: The replacement procedure for Mass Air Flow Sensor requires handling the Mass Air Flow Sensor with precaution to maintain the honeycell in the air inlet end and protection of the sensing elements from contact or contamination by cleaning solvents or lubricants. A little non-silicone lubricant helps installation by applying it to the air duct. The replacement process starts using these steps: unplug the Mass Air Flow Sensor electric connector then remove the air cleaner assembly followed by unscrewing the Mass Air Flow Sensor clamp from the air cleaner duct and completing the operation by removing the Mass Air Flow Sensor retaining bolts before fully extracting the Mass Air Flow Sensor. Install the Mass Air Flow Sensor by placing its embossed arrow facing toward the engine before inserting it into the air cleaner housing while tightening its retaining bolts until they reach 11 n.m (97 lb in). To finish the procedure, seal the air cleaner duct clamp firmly and put back the air cleaner assembly before reattaching the Mass Air Flow Sensor electrical connector.
