C5 year 2000. Check engine light came on diagnosed with MAF sensor, having trouble removing on air filter section

Q.  I’m working on my C5 year 2000. Check engine light came on diagnosed with MAF sensor, having trouble removing on air filter section. Any Ideals

A. Essentially we first make sure we’re using the right tool. In other words if they are Philips screws are you using the proper tip because there is a huge difference in the taper of Philips screwdriver tips. Same is true of TorX and other bits. That may sound ridiculous but you would be shocked at how many times in a month we get cars in with fasteners that the owner couldn’t remove simply because they weren’t using the proper tool.

Assuming you’re using the proper tool the next thing is to use a high quality rust and corrosion solvent we use BG Products In-Force which has done a great job here in the shop. If the bolts are hex and are rounded use a special spiral socket designed for damaged bolts. If they are Philips or straight and the slots are damaged we use screw removal grit from the home center. And last but not least we use the most trusted tool in the shop for removing difficult fasteners; heat.

We have tiny butane torches that can be used to heat very small bolts, etc. When dealing with plastic housings with imbedded nut-inserts we take small pieces of sheet aluminum and cut them to fit around the bolts then clamp them to the plastic to help prevent melting the plastic. If everything fails we buy or make a new part. In a case like this a new part may mean drilling the old fasteners out and then fabricating a new plate to replace or overlay the old damaged portion of the housing.
