I have a 1995 Volvo 850 and the two screws that secure the maf sensor are unkown to me. They look like a secure torx but appear to have onlu 5 sides rather than six! Can someone tell me what they are and the size of tool I need to remove them so I can clean my maf sencor.

Thank You
Raymond

 

Mine were security torx bits. I have never seen them be 5 sided. A lot of folks replace the housing along with the maf.

 

Try an allen, otherwise see if you can use a small flathead screwdriver
