Audi A8 Timing Belt Replacement for 4.2L 40 Valve Models

Audi S8 Timing Belt Replacement 4.2L 40 Valve

The 4.2 liter 40 valve V8 engine was used in 2001-2003 Audi S8 D2 Platforms. The 40V V8 engine is driven by a timing belt system which links the cylinder heads, camshafts, and crankshaft to run in sync. This Audi S8 timing belt system consists of a wear resistant, high strength, corded/molded rubber timing belt (a.k.a. Audi S8 toothed belt). There's also an assortment of tensioners and idler rollers to guide and tension the Audi S8 timing belt.

It's very important to service your 4.2L Audi S8 timing belt. The timing belt, tensioners, and idler components eventually reach the end of their recommended service life. The D2 S8 4.2L 40V is an interference engine (a.k.a. non-clearance engine). If the Audi S8 timing belt fails, the timing belt system that links the cylinder heads, camshafts, and crankshaft no longer run in sync. Close tolerance engine designs allow for the cylinder head valves to hit the top side of the pistons. Timing belt failure on these engines usually results in catastrophic engine damage (i.e. bent valves and in some cases cracked pistons).



D2 Platform

The D2 platform S8 4.2L has two different timing belt system possibilities. The various systems depend on model year and/or VIN number.

2001 model years have two different timing belt system possibilities. Owners will need to confirm if they have the early or later system with their VIN #.
It is the responsibility of 2000 S8 owners to determine which system (Early or Late) they have using the last last 6 digits of their vin#. [System Details]

2002-2003 model years had only one timing belt system option. Owners will NOT need to confirm their engine code or VIN #.
