In my car, the space between idler and tensioner bearing bolts and the chassis is so limited (as per the following picture) that you can't use a torque wrench. In fact, the torque wrench itself can be put in the area but you can't attach any socket to it. I had to use a ring spanner to tighten the bolts but first, I practiced with my torque wrench to get the feeling of the required torque specs (with other bolts on the car) to avoid over-tightening the bolts.
Is there anyway to use a torque wrench in my next service?

2I've taken a socket and ground the length down to fit into such spaces. I know there are some "stubby" sockets on the market but they tend to be expensive.– jwh20Aug 18, 2021 at 9:31

2I would apply basic physics: Torque = Force * Distance, so take a spanner of x length which fits and pull with y force... Simple, just need to understand what you are doing.– Solar MikeAug 18, 2021 at 10:40

2You can also get a narrow "break over" torque wrench such as here. The elbow folds when torque is exceeded.– Weather VaneAug 18, 2021 at 19:01

1Have you checked to see if you can access this area through the fender well? If so, an extension used properly will accurately allow you to torque these bolts.– Pᴀᴜʟsᴛᴇʀ2 ♦Aug 18, 2021 at 21:57

1Which car/engine do you have? If you tell us, someone may know how you get access.– HandyHowieAug 19, 2021 at 8:32
