who makes a good serpentine belt tool/kit that isn't pure junk but doesn't break the bank? i heard a lot of times the drive end breaks off.
Gear wrench. Best $50 I ever spent


I like a 1/2" breaker bar for that job.
There are a few out there like 24v 5.9's and 6.7's that are almost impossible to do without a belt tool.^^^THIS! I guess there are some vehicles that require a special tool, but every one I've worked on simply used either a breaker bar or a box end wrench.
My Volvo 850 tensioner pulley has a square hole. I bought bar stock, ground to the fit, and welded the bar to piece of 1x1/8 steel

i have always used a 1/2 breaker bar but when doing FWD cars (transverse mounted engine) its sometimes a pita and something thinner would work alot better in those cases. thats why i was wanting a dedicated tool.
When I changed my volvo it used a T60 torx and my gearwrench kit did not help me at all. It has worked very well on other vehicles and I have figured out how to make my own adapter to allow use of the proper torx bit for the next time. It was a real PITA with a ratchet and socket. A few people say there is a plastic cover that can be removed and that will expose a 14 MM bolt, I may see if that is true next time, but if I make the adapter, it won't matter any more.
Can anyone with the newer gearwrench set share the item number of the ratcheting flex wrench? I'd like to upgrade without buying the set again.
I don't know why Volvo made stuff so complicated. The old style tensioner seemed like a great design. I can't imagine needing something like this to work on never Volvos... But I suppose if it makes things easier and saves you time... I suppose them the $43 price tag makes sense.
Most engine compartments have a vertical space and the tensioner is perpendicular to that vertical space, if you get off to an angle you would ram your hand into something.I am not sure that the locking flex would be that useful.Most engine compartments have a vertical space and the tensioner is perpendicular to that vertical space, if you get off to an angle you would ram your hand into something.
