2007 Impresa Base Idler Pulley Replacement

Featured Replies

I just bought a Subaru OEM timing belt kit. It includes the cam seals, waterpump and gasket,gear pulley, timing belt, new tensioner assembly, lower coolant hose(with a bend)  two drive belts and I also bought upper and lower coolant hoses. It did not include the the two idler pulleys(upper is a single bearing and the lower is a double bearing). Is it advisable to use the double bearing idler pulleys in the top and lower positions? Someone told me that the double bearing idler is much more durable. Who is the oem supplier of these pulleys to subaru? Or do I have to buy them directly from the dealer? $56 each ouch......

They are easy to find for around $30 and even less.

Koyo Seiko which merged with Toyota in 2006 which is now JTEKT? Just to be clear, are the Koyo idler pulleys as high quality as subaru oem?
