Mar 7, 2014 · ENGINE AND ENGINE COOLING:ENGINE

The Gates Corporation (Gates) is recalling certain aftermarket Tru-Flow Water Pumps, part number TFW 41127, sold at certain NAPA Auto Parts and/or installed by automotive service technicians after November 1, 2013 (and manufactured August 2013 through October 2013) that have a black-colored pulley/sprocket or do not have 'US9377' stamped on the water pump housing. These service replacement parts were sold for use in model year 1999-2005 Audi A4, 2000-2006 Audi TT, 1998-2005 Volkswagen Beetle, 1999-2006 Golf, 1999-2008 and 2011-2013 Volkswagen Jetta, and 2000-2005 Volkswagen Passat. In the affected water pumps, the pulley or sprocket that turns the timing belt may develop microfractures causing the timing belt to fail.

Consequence: A failure of the timing belt may cause the engine to shut down, potentially increasing the risk of a vehicle crash.

Remedy: Gates will notify owners, and dealers will replace the water pump, free of charge. The recall began during May 2014. Owners may contact The Gates Corporation at 1-303-744-1911.
