The 4.2 liter 40 valve V8 engine was used in 2000-2004 VW Touareg (US) 7L chassis. The 40V engine is driven by a timing belt system which links the cylinder heads, camshafts, and crankshaft to run in sync. This VW Touareg timing belt system consists of a wear resistant, high strength, corded/molded rubber timing belt (a.k.a. VW Touareg toothed belt). There's also an assortment of tensioners and idler rollers to guide and tension the VW Touareg timing belt.
It's very important to service your 4.2L VW Touareg timing belt. The timing belt, tensioner, and idler components eventually reach the end of their recommended service life. The 7L Touareg 4.2L 40V is an interference engine (a.k.a. non-clearance engine). If the VW Touareg 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. VW Touareg timing belt failure on these engines usually results in catastrophic engine damage (i.e. bent valves and in some cases cracked pistons).
We're pleased to announce our partnership with Schaeffler Group Automotive, one of Germany's and Europe's largest industrial automotive companies who have been manufacturing timing belt components under the official Original Equipment (O.E.) INA brand for decades. Partnership with an O.E. manufacturer means Blauparts can ensure absolute quality control through a direct supply chain. >> Read more about Schaeffler.
BLAU® Official O.E. INA BASE VW Touareg Timing Belt Kits include the same timing belt and timing belt tensioner(s) components that were fitted on your car from the factory. Beginning in May 2013 Blauparts began to include an INA BASE kit in nearly all of our VW Timing Belt Kits. Hundreds of INA part numbers were entered into our database. As of January 2014, approximately 90% of BLAU® Official O.E. INA VW Timing Belt Kits include a BASE INA kit and have been fully integrated to Gen II status.
Gen II BLAU® VW Touareg Timing Belt Replacement Kits for the 4.2L 40 valve engine contain a preassembled INA timing belt BASE kit. The timing belt, timing belt tensioner, lever, eccentric idler bearing, and tensioner damper contained in these kits are the same as those directly supplied to the O.E. automotive manufacturer (e.g. VW) and those that were installed on your vehicle on the assembly line.
