Aluminum threads can be a little soft, so it's recommended that you only tighten to the recommended torque spec so you don't strip the threads out. This is true even outside of engines. I've had aluminum oil coolers on different pieces of equipment where the flange seals are bolted on and the aluminum threads fail because someone was a gorilla and cranked it down waiting for it to get tight and pop goes the threads. Sure, you can usually tap and install steel coil replacements in most cases, but you need to have enough metal surrounding the hole to be secure enough for that, not to mention other wonderful things that can occur when you get into that. Better to go with ounce of prevention (torque wrench) than pound of cure (costly repairs). Just my $.02
Thanks for your input!
One thing about torque wrenches is how can you trust them being calibrated correctly? What's a good all around trusted torque wrench and is it recommended to have a couple for particular jobs?

Very good question. My answer may come as a shock to some, but I used to service air compressors at a company in southern California that specializes in calibration of sensitive equipment and tools like meters, calibrating weights, scopes, gauges and yes, torque wrenches. Given my line of work, I also found this to be important information, so I asked one of the senior calibration technicans this very same thing. His response: in his years of experience, the torque wrenches he has seen that hold their settings the best came from Harbor Freight tools (!?!?!? Wtf???). I was shocked. Then he proved it. A snap-on, a Mac, and an HFT were all tested against a calibrated setup with a 100 lb/ft nut and bolt. The HFT was dead on, the other two were off by at least a couple pounds and needed to be adjusted. His point was simple: they were all used as primary tools from their respective shops, and all saw about the same amount of use over a 2 year period. The important thing with any wrench is make sure it is stored in it's case, try not to drop it if you can help it, and make sure you reset it to 0 lb before you put it away. Leaving it stored without resetting it puts strain on the internals which will cause it to go out of calibration. I had him test my wrench, also HFT, and it clicked when it was supposed to.
Now, there is no way to guarantee that each of the three tested wrenches was cared for in the same way, but the Mac came out of the box locked on to 85 ft/lb. The other two came out of the box at 0. The Mac was the furthest out. The snap-on was only off by a couple pounds. So I figure mileage may vary here. Just find one that reaches your desired specs and care for it as a specialty tool, because that's what it is. Keep it clean and don't store it locked on to a particular setting aside from zero, and you should be fine.

You should have one that's dedicated to foot pounds and one dedicated to inch pounds since the smaller stuff is more likely to be torqued in inch pounds and an inch pound wrench is going to be smaller as well for this type of application. One foot pound is 12 inch pounds, so the tolerances are tighter on an inch pound wrench.

I would never have guessed HFT would be the place to get a tool such as that! Awesome really!

Not sure if your familiar with Chris Fix on Youtube, but I recently saw a vid of his on torque wrenches and he recommended one priced about $50 from Amazon. I thought about getting it, but then thought it's probably better to not have one shipped as it would probably be thrown and tossed around much more through delivery then getting one at say HFT. I think I'll go with your suggestion. Is there a way to test the accuracy without paying for one to be calibrated after purchase?
Thanks again for your time!

You stated that the BFT torque was the only one that was in calibration, which I find interesting as well, my question would be that HFT actually doesn't make any of the tools they sell, they have 3 different brands of torque wrenches listed on their website... Pittsburgh, Icon, and Quinn...which of these brands is the brand you're referring too as a "HFT" torque wrench?

I would also suggest you get the 1/4" drive Pittsburgh torque wrench as well since it's the one that will torque in inch pounds, the 3/8" and 1/2" drive both torque in foot pounds, both the inch pound and the foot pound torque wrenches are needed for the various different size bolts and nuts on any passenger type vehicles.

Which one you use will depend on the actual torque specs of the fastener you're dealing with.

If memory serves, it was a Pittsburgh 1/2 drive like the one I have. Pretty sure that's all they carried until recently. I've had mine since 2007. Was tested in 2014. Hasn't been tested since.
