TIA. I have to replace the fan clutch on my 2003 yukon. It has the 5.3 and the tow package. My local options are car quest for around $70 and brand is unknown according to them. Pep boys for $56 and is Hayden. Advanced auto which is Imperial for $56 which I believe is the same as Hayden. Or Napa which is naps own Temp brand for around $60. With the research ive done for Temp brand the best guess I have come up with is that its made by 4 seasons. And I can get a discount if my friend buys it from napa. Not sure how much of a discount but I can get one. One thing that concerns me is advanced auto and pep boys are the only ones to ask about the tow package and they list a different part number for it with and without the tow pkg, while the others list the same part #. Does it even really matter? I do not tow anything at this time. TIA.
