I just replaced my tensioner with a new Gates unit tonight. I haven't driven it yet but I like the metal pulley vs. the plastic unit from Dayco. I had replaced the pulley itself at 75k miles with the Dayco. I probably could have gone with just a pulley replacement and bought the Gates pulley but I have 145k on the Mazda5 now. The last thing I need is to be out of town and have the van get overheated due to throwing the belt.
Ironically the black oil cooler on our van blew it's seal in spectacular fashion while on the ramps. I'm off to buy the silver replacement unit tomorrow at the stealership. Once it's back together I'll report back if the new tensioner fixed the sound.
