Can you drive with serpentine belt off?
Under no circumstances can you drive a vehicle without a serpentine belt because the serpentine belt serves the important function of delivering antifreeze to important parts of the engine. The serpentine belt drives the water pump, and without it, there is insufficient coolant flow to maintain the engine temperature.
How to make serpentine belt stop squeaking and when?
While keeping the engine in running state, spay the belt dressing onto serpentine belt and back of the fan belt. You don’t need to move the spray around the belt; the running engine will spin it, and allow to spread the belt dressing to the entire belt. The squeaking sound should stop by now.
How do you change a serpentine car belt?

How is the tension set on a serpentine belt?
Depending on the application, your serpentine belt will either have tension placed on it using a movable bracket or an auto tensioner pulley. This pulley uses an internal spring to apply consistent pressure to the belt at all times. If your vehicle does not have a tensioner pulley, the alternator bracket is likely how tension is set on the belt.
What makes a serpentine belt make a squealing noise?
The tensioner is a self-adjusting pulley that maintains pressure on the belt to reduce slipping. At times, the bearings in the tensioner pulley become worn. This causes the squealing noise. Check these bearings when performing a belt change. Serpentine belts have that name for a reason.
