I am soon doing a coolant change on my car, including draining the coolant from the block using the drain plug, and I have heard of a few people apparently snapping these off due to over torquing them, so I was going to invest in a torque wrench.
My manual says the torque should be 25Nm for the drain plug, and I am looking at a torque wrench with a range of 28Nm to 220Nm, as it is the best value and has a very large range.
Will this extra 3Nm make a difference? I'm not sure how to quantify it but I'm guessing that is virtually no difference at all.
Also, is it wise to use a torque wrench like this with such a large range, or do people tend to have a low torque wrench and a high torque wrench?
