Torstein 3PK780 fan belt: 3-rib multi-rib belt, 780 mm (budget)
The Torstein 3PK780 is a 3-rib multi-rib drive belt (also called a fan belt, V-ribbed or serpentine belt), 780 mm long. It drives the engine auxiliaries. For example, it turns the alternator, the power steering pump and the air conditioning compressor, depending on the engine.
Torstein is the budget option in our belt range. In other words, you get the correct rib count, length and rib profile for less than the premium brands. Want the step up? The Continental 3PK780 is the same size from an original equipment supplier.
How to check your belt size
First, look at the back of your old belt: you will find the size printed there. For example, in 3PK780, 3 is the number of ribs, PK is the rib profile and 780 is the length in millimetres. However, sizes a few millimetres apart (such as 3PK780 and 3PK785) are different belts. So match the number exactly, or ask us.
Vehicle fitment
The manufacturer catalogue has no passenger-car vehicle list for this belt. Sizes like this mostly run on trucks, buses, agricultural and industrial engines. So match the size printed on your old belt, or send us the vehicle or engine details and we confirm before dispatch.
Check before you order
Fitment lists come from the manufacturer catalogue. However, the same model can use a different belt depending on engine, air conditioning and power steering. So compare with the size on your old belt, or send us your registration number or VIN and we confirm before dispatch.

Fitting tips
Replace the belt at the interval in your service book. Also replace it sooner if it is cracked, glazed, missing ribs or squeals on start-up. At the same time, check the tensioner and idler pulleys, because a worn tensioner bearing wears out a new belt quickly. Before you remove the old belt, photograph the routing. Finally, make sure every rib sits in its pulley groove before you start the engine.
