Torstein 5PK820 fan belt: 5-rib multi-rib belt, 820 mm (budget)
The Torstein 5PK820 is a 5-rib multi-rib drive belt (also called a fan belt, V-ribbed or serpentine belt), 820 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. Listed fitment includes the Toyota Conquest, Dyna & Mazda RX-8.
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.
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 5PK820, 5 is the number of ribs, PK is the rib profile and 820 is the length in millimetres. However, sizes a few millimetres apart (such as 5PK820 and 5PK825) are different belts. So match the number exactly, or ask us.

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.
