The Gates 5PK903 is a 5-rib multi-rib drive belt (also called a fan belt, V-ribbed or serpentine belt), 903 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 Mitsubishi Lancer.
Gates is one of the world’s largest drive belt makers. Also, it supplies original equipment to many vehicle manufacturers.
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 5PK903, 5 is the number of ribs, PK is the rib profile and 903 is the length in millimetres. However, sizes a few millimetres apart (such as 5PK903 and 5PK908) are different belts. So match the number exactly, or ask us.

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.
