How do you change the supercharger belt tensioner in 1997 Pontiac Grand Prix GTP?
no
means the car has a supercharger
put a socket on the tensioner pulley and pull on it until there is slack then just slip it off.
gm supercharger oil for the supercharger. any oil you prefer for the engine oil.

A 1999 Grand Prix GTP uses an EATON M90 supercharger that displaces 90 cubic inches of air during every revolution. This results in a rating of 240 horsepower at the crank at 5200RPM, and a "pavement pounding" 280ft-lb of torque at 3600RPM!
