Should not be hard at all to replace yourself. I see you're in Torrance, if you get the belts yourself from a dealer Technosquare can swap them out pretty quickly. My smaller belt had cracks in it before the larger belt did.
When did you change your belts? 43k miles sounds a little low for the belts to be cracking already right.
I still have the stock smaller belt on my car with over 40,000 miles.
Changing them is pretty easy but to change the smaller belt you have to take off the bigger belt.
Have you inspected your smaller belt yet? Mine has a lot of cracks, just a little worried. How many more miles do you have when it's showing a lot of cracks?
does the 45's have the same amount of belts as well 1 big and 1 smaller one. I can't find 2 on the infinitipartsusa. just the 1 bigger one.
The FX45 uses two belts.
Took me 30 min to replace both belts. There are tensioners on each belt that allow you to loosen and slack the belt for removal and replacemnt.
I went with the Goodyear Gatorback belts from autozone. About $50 for both. These have softer feel to them and have sectioned grooves that make them extremely quiet.
Tip while you are at it: remove the whole tensioner pulleys and clean/re-grease them to keep them quiet for the next 60K miles.
I still have a question on how much to tighten the four bolts.
Is there a torque range for bolts a and c?
Do you tighten bolts b and d until the belts "look" tight and let the auto tension mechanism handle the rest?
i went to autozone yesterday and the guy there argued with me that i only have one belt. i just walked out.
