before I began the tear-down of my 7m to get it ready for the spring/summer I decided to take it around my neighborhood one last time with my girlfirend in the car,not necessarily to run through the gears but to cruise in first. Only at 10 pounds I got on her a few times only to return to my driveway and pull it into my garage. as im sitting in the car I hear a tapping so I step out of the car and I manage to pinpoint the sound coming from near the radiator but not sure what it could be hoses are on snug any help here would be appreciated
