BMW
E34 Belts
Your BMW's drive belts are wear items, and will degrade and crack over time. Don't wait until you have a belt failure... don't get stranded! Replacing your BMW's belts, such as the alternator belt, power steering belt, air conditioning AC belt, or serpentine belt is a low cost insurance policy to preventing a break down -- or worse, engine damage. We recommend checking your belts every 10,000 miles. If your belts have excessive cracks, dry rot, missing teeth and/or grooves, are cause noise, it's time for new ones.
While also inspecting your serpentine belts, also check for wear or resistance in the pulleys. The tensioner pulley and deflection pulley are the primary sources for belt squealing. The rubber-isolated pulleys can also break apart, leading to total belt failure. We sell the tensioner and deflection pulleys for the M50 engine family used in the E34, E36, E39, E46, X5, Z3, and Z4.

Hydraulic Belt Tensioner - E36, E46, E39 6-cyl
(more info)
Hydraulic Belt Tensioner for E36, E46, E39 6-cyl models. This is the oil-filled tensioner that keeps the main drive belt in the proper tension.

This can be done during any belt or pulley service or anytime the fan is off the engine.
NOTE: These BMW's may have been equipped with either a mechanical or hydraulic tensioner. Only for cars with Hydraulic Belt Tensioners. Please check before ordering.

Tensioner Pulley for Main Drive Belt (Water Pump/Alternator/Power Steering)
(more info)
This is the tensioner pulley, also known as the adjusting pulley and lower pulley. This pulley is mounted on the belt tensioner near the center of the belt assembly. The upper and lower pulleys are known to be the primary sources for 'belt squealing'. This pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).
This pulley is mounted along with the hydraulic or mechanical belt tensioner but can be replaced on its own. It is used for the main drive belt on the M50-family engines (M50, M50TU, M52, S52, M52TU, M54, M56, and S54 engines). This is the same belt that covers the water pump/alternator/power steering systems. Replacement is a very easy procedure (requires fan removal) and will have your engine purring in no time. Belt replacement is strongly recommended at the same time.

Timing Belt and Tensioner Kit - E30 E28 E34 - M20 engine
(more info)
This M20 Timing Belt package comes with the two main components to change your E30, E28, or E34 timing belt - OEM Continental belt (1131171361) and an OEM tensioner (11311468743). Both are the highest quality OEM parts that we have trusted for close to twenty years. The timing belt on the M20 engine should be replaced every 50,000 miles.
We would also recommend changing the water pump and your accessory belts at the same time since both are accessible at the front of the engine when you're replacing the timing belt. The Bentley Service Manual is also the perfect companion for this type of job.
This item fits the following BMWs:
1984-1991 E30 BMW 325e 325es 325i 325ic 325is 325ix

Upper Idler Pulley for Main Drive Belt (Water Pump/Alternator/Power Steering)
(more info)
This is the Upper Idler Pulley, also known as the roller pulley or deflection pulley. The upper and lower idler pulleys are known to be the primary sources for 'belt squealing'.
