Startup Squeak - ZR-1 Net Registry Forums

XfireZ51 · 10-04-2018

Don't know why, but it seems that as temperatures are dropping, initial startup of the cold engine brings w it a squeaking coming from the area of the serpentine belt, tensioner, and alternator. It goes away once the motor is warmed up and subsequent startups do not exhibit the same. The last time something like this happened, the alternator went out. Current alt is a reman'd Delco unit w fewer than 5K miles on it. I also did replace an older tensioner w a newer one.
Any thoughts?
