So, I believe my grooved idler pulley bearing is going out. I see that Dorman, Dayco, and Gates make that pulley. Is one of these brand's pulley better (in quality/longevity) than the other two, or is it a wash?

There's about $7 price different between the Dorman and the Dayco, with the Gates sitting in-between them for price.

Also, while I'm doing it, should I replace the smooth idler pulley, and smooth tensioner pulley - or is that unnecessary preventive maintenance?

Additionally, my upper radiator hose rotted out and started spewing coolant all over; question, does anyone make a red upper radiator hose or do I just go with http://www.amazon.com/Dayco-71850-Up...rix+upper+hose ? Also, should I replace any other coolant hoses while I'm doing it?

Thanks in advance!
