Quick Question

Going to help a lady out here at work. The mass air flow sensor went out on her car. I am going to replace it for her. It is a 2002 escort nothing special. Is it right on top and easy to get to? and can someone tell me if it is allen keys? star screws? or normal screws.

Thanks in advanced

well i have delt with meny escorts and found out you can never know until you look. some come with 7 or 8mm head bolts or T20 torx(star) but im doughting allen heads

sounds good thanks
