How do I choose the right torque wrench?
Choose a wrench with an accuracy of plus or minus 5%. Check the torque wrench calibration for the date and accuracy as per the manufacturer’s settings. When a torque wrench is well-calibrated, it will have clear scale visibility. The longevity and accuracy of the torque wrench depend on how well it is stored.

Is it worth buying a torque wrench?
If you plan to do any major work on your engine or on some major powertrain components, you absolutely need a torque wrench. Overtightening cylinder-head bolts, for instance, can easily cause expensive damage and catastrophic coolant loss. Too-tight exhaust manifold bolts can cause the manifold to crack.
What happens if spark plugs are not tight enough?
if not tightened properly the spark plug will work out of the hole & most likely damage the threads on its way out. If a spark plug is cross threaded it will damage the plug & threads in the head. Some times a reamer thread tool can repair the head. Or the head may have to be removed to repair.
Should you use anti seize on spark plugs?
NGK spark plugs are installed at the factory dry, without lubrication or anti-seize. Metal shell stretch changes the heat rating of the spark plug and can result in serious engine damage caused by pre-ignition. Do not use anti-seize or lubricant on NGK spark plugs. It is completely unnecessary and can be detrimental.
How long should an engine cool before changing spark plugs?
How Long Should I Let My Engine Cool Before Changing Spark Plugs? An overheated engine should cool down to a temperature where it is safe to inspect and potentially work on it within a minimum of 30 minutes.
What can I use if I don’t have a spark plug wrench?
A regular deep well socket will work. You just need to take care not to damage the porcelain insulators, since there’s no rubber grommet inside like a plug socket. Most late model engines use a 14mm plug socket; some use a 5/8″ (or 16mm).
What is the most accurate type of torque wrench?
Dial-type torque wrenches are generally considered to be one of the most accurate types of the torque wrench. The dial-type wrench is the only type of torque wrench where the final reading is not easily affected by the hand-hold position on the wrench.
Are digital torque wrenches better?
Digital torque wrenches have a big advantage over other types of torque wrenches when it comes to their scale reliability because they have prominent displays that show the current torque reading.
Is it OK to loosen bolts with a torque wrench?
So long as users operate with caution and do not exceed the maximum torque, most torque wrenches can be used for undoing. By exceeding the maximum torque limit during a bolt loosening you can affect the wrench accuracy, causing problems for future use. If in any doubt, use another tool for loosening bolts.
Is a ratchet the same as a torque wrench?
Torque wrenches are a type of wrench commonly used in automotive work and other tasks where a precise torque setting is needed for a specific bolt. Ratchet wrenches are more simple wrenches designed for loosening and tightening bolts.
Is it OK to hand tighten lug nuts?
There are a couple of tools you can use to get lug nuts just as tight as a torque wrench. With a crossbar tire iron, choose the right size socket and tighten by hand if you have the arm strength. If not, you need to stand on the right side of the tire iron to turn and tighten the lug nut clockwise.
Are Pittsburgh tools good quality?
Pittsburgh tools are known for their unbeatable value and exceptional quality. Some of the hand tools that Pittsburgh makes are screwdrivers, ratchets, wrenches, pliers, and sockets – in addition to many others. The average rating of Pittsburgh tools in reviews across the web is a 4.5 stars out of 5.
Do you put oil on new spark plugs?
It’s very important not to over or under tighten spark plugs during installation. If your engine has the more modern ‘COP’ system (coil-on-plug) then lube the spark plug boot with dielectric grease, this helps prevent misfires and makes removing easier in the future.
