Tappet wrenches are usually long and quite a bit thinner than the normal open end wrench. They are indispensable for adjusting valves and helpful for getting into tight places.

There are numerous types and styles of pliers. They come in all shapes and sizes from the slip-joints that almost everyone has in the kitchen junk drawer to extremely specialized kinds for use on very limited applications. The be-ginning technician should have a few basics, though.
Slip-joint pliers are the type everyone recognizes. They should never be used anywhere that a wrench should be used, but they are an asset in many places to hold objects.
Unlike slip-joint pliers, Channel-Lock pliers have a tongue and groove arrangement, so they can accommodate a number of jaw openings. Water-pump pliers look a lot like Channel-Lock pliers, but instead of the tongue in groove design, they have the pin and multiple holes arrangement like slip-joints. The Channel-Lock pliers are less likely to change jaw openings during use than the water pump pliers.

All torque wrenches should be occasionally tested and adjusted should t lose their calibration.
"Don't force it. Just get a bigger hammer." That's a joke, and in fact, most professionals will avoid using a hammer unless it is a last resort. However, there are several places where nothing else will do.
You should have at least one twelve ounce ball-peen hammer. Us< chisels and punches. The ball-peen is useful for reforming bolt holes i metal like oil pans and valve comers.
You also should own at least one soft-face hammer. Soft-face hammers damage parts like steel ones. The face deforms instead of the part being s Dead-blow hammers have heads that are filled with shot. Since the shot continues the force after the hammer makes contact, rebound is reduced.
For heavy duty purposes you also should have one big hammer in the two to three pound range. Many technicians select one known as the engineer's hammer. One side of this double-faced hammer looks like a conventional sledge hammer. The other face is wedge shaped.
The automotive technician encounters many items on the job that do not simply slide off their mating part. This is where the puller is needed. The first one to get is a battery cable terminal puller.

Chisels and Punches

Punches and drift pins are essential. Punches are necessary to make a dimple in the metal before drilling. Drift pins come in a variety of diameters, and only the correct diameter punch should be used to prevent damage to the component. You should buy a good assortment of punches and at least a couple of chisels to start with.
Electronic Diagnostic Tools
Electronic control units, which are actually minicomputers, now affect all of an automobile's operating systems. From ignition to exhaust, electronic systems are vital, and the technician needs special tools to repair these high tech machines. Technicians often buy their own diagnostic instruments, at least the often used, handheld models. Repair shops usually buy the larger diagnostic "master computers" and monitors that their technicians use in the shop.
A technician who wants to be ready for electronic diagnostics now needs at least three specialized tools, says Charles Gorman, technical manager of the Equipment and Tool Institute:
- A scan tool is the device that processes and displays vehicle data link information.
- A digital multimeter is a test instrument that measures both AC and DC voltages, resistance, frequency, pulse width, and amperage all on a digital readout.
- A graphing multimeter or digital storage oscilloscope is a meter that captures high frequency electrical signals via a glitch capture or record function, allowing the technician to diagnose the problem.
