Two drive belts on the 93-97 altima 2.4.
3 drive belts on both the 4 and 6 cyl. + timing belt on 3.3 v6
I replaced an alternator on a 2002 Nissan Altima but the drive belt is now too loose even with it having an automatic belt tensioner
By replacing the belt tensioner, this is a serpentine belt systems there is no adjusting the alternator bolt tighten the drive belts, if the belts are loose you must replace the belt tensioner and the belt to retain optimum performance from you Charging sytem as well as you other equipment being driven by the belt system.
On 4th generation Nissan Sentras (1995-1999), as well as almost all front-wheel drive cars ever made, the belts are on the right side of the engine, almost against the right side of the engine cavity.
First of all, they are the same as the fan belts on any other car. The fan belt(s) are the serpentine drive belt(s) that turn your fan and other accessories (like alternator, compressor, power steering) They are often referred to as serpentine belts, drive belts, and accessory drive belts. The are located on the outside of your engine, driven by the main pulley (crankshaft pulley). R. Mesyef
The life of serpentine and drive belts depends on the application, belt component quality and them being free of fluid contamination. New belts can often last 50-100,000 miles. However, it is always recommended to preemptively replace hoses at or before the manufacturer suggested mileage.
Came up to a stop light and when the light changed the car would not move.
The Drive belts are for powering your accessories( power steering pump, alternator, a/c compressor). The VQ30de engine in your car has a timing chain, which is designed for the life of the motor. (a lot of import cars have a cam drive belt, that needs changing or risk engine damage).
remove the varable speed pulley-replace both belts re-install varable speed pulley--your done.
There are two sensors 1 is by the crankshaft pully (by the drive belts) the other is between the engine and transmission it reads from the flywheel
how do you replace the drive belts on an 1974 mercedes 230
