Got a new torque wrench ready for when I tackle cam cover change.It's a Toolzone make,feels a little stiff to me but that could be just because it's new,or maybe it's just a crap make I don't know.Anyway is there any way to tell whether it's clicking off at the correct value?Something else on the car that's the same torque that I can try on or some other way?

Try the ones holding the 'breather' plate on (under the Eco plate)...they are 8nm, also the four bolts facing forwards on the throttle body attached to the Plenum....sure they are 8nm too

Hold the square in a vice so that you can hang a weight on the handle at specific distance. Set the gauge at eg 50Nm and then hand 50kg at 1 metre ... it should 'brake' if correct

[deviator]

As these bolts are normally overtightened, couldn't you set it 8nm and try and undo them. If it clicks before they crack, then either you wrench is low or the bolts too tight.

Wouldn't the 1-2Kg the wrench weighs throw this out?

Fixed.

Ta!

It's been a while since I did Physics O level .... but I was close

Had to think about it for a minute myself.

no idea, but I'd not worry over 1 or 2kg or a couple of Nm or lb/ft either way

I'm still thinking .....

Only a factor of ten out.. I hope you're not a nurse, Andy!

You're wise to check it baza. I purchased my naff low range torque wrench. And I stupidly just dived right in expecting it to click at 8nm on cam covers. Bugger didn't click at all. Not even slightly. This was mid job so I had no choice but to just snug them up. Seems to have worked out. Hope yours works ok

weights as accurate as a fat bird on a diet!

[Bigron]

If you have the wrench horizontal so that the weight of the lever isn't a factor, you can apply the torque with a spring balance or, preferably, one of those cheap portable digital luggage scales from Lidl/Aldi and pull on it to the required force.

So simple it's genius, I feel stupid.

Hey lad,

If you're in my neck of the woods feel free to compare yours with my wrenches. They're a little and largest ones halfords do. Made in England and each comes with a calibration certificate. Both used less than a dozen times.
