It looks like my fan clutch/viscous is not working properly when the VX is at operating temperature and stop/go traffic. I wanted to find out if anyone has used an aftermarket one with no issues. The factory part from Merlin is $227.68 but checking at the O'Rielly's, Checker, and Autozones, the Torqflo and Hayden fan clutches are going for about $100. I don't want to cheap out on the cooling fan clutch if the factory one is the way to go (proper specs.etc). Thanks for any feedback.
