7 Most Essential Pliers for Automotive Repair

You just started working in an auto garage or are a self-taught mechanic but don't know the essential pliers you need for automotive work? This article is for you.

As much as powered tools are becoming more common in the automotive industry, hand tools will always have a place. Some of the hand tools that are hard to replace are pliers.

Pliers are good for gripping, squeezing, cutting, and twisting. Some are specially designed to accomplish specific tasks. For example, snap ring pliers are specially designed to install and remove circlips or snap rings while exhaust hanger pliers are for removing exhaust hanger rubber.

Which are the most essential automotive pliers?

Because there are thousands of pliers in the market for automotive and general use, it can be overwhelming to choose just a few essential ones for your automotive works. That is why I have put together this article to share some important car pliers you must always have with you as an auto technician. If you are a beginner mechanic, this set of auto repair pliers should have a place in your tool backpack or pliers drawer on your tool chest.

1. Retaining ring pliers

Another name for retaining ring pliers is snap ring pliers or circlip pliers. These are special types of pliers for removing or installing retaining rings or snap rings in various mechanical assemblies.

Snap rings are special ring fasteners for locking assemblies in place. They are of different types and shapes but can be broadly classified as either internal snap rings or external snap rings.

Likewise, snap ring pliers are either for internal snap rings or external snap rings. However, some snap ring pliers are multipurpose. They have convertible jaws that let you use the pliers open and close both external and internal circlips.

Check out this article to learn more about snap ring pliers. You will also find some of the best snap ring pliers set that I recommend.

Types of snap rings

Internal snap rings or retaining rings keep round shafts and assemblies inside a bore housing. They are installed inside the bore to keep the assembly components from falling out.

A good example of an internal snap ring is the one that keeps the wheel bearing of a car inside the wheel hub.

External retaining rings, on the other hand, hold round components on a shaft. You will come across them when assembling or disassembling various shafts.

For example, when working on a vehicle’s transmission, you will encounter several retaining rings that keep gears in place on the shafts.

Inner CV axles also have snap rings for retaining the cv joint onto the drive shaft.

These are just a few examples of where your retaining ring pliers will be useful in your car repair project.

Why use snap ring pliers?

Although you can try other hacks to remove circlips when you are trapped, the most appropriate way to remove or install any retaining ring is with retaining ring pliers. These pliers have strong jaws for squeezing or expanding a snap ring in or out of the groove. These pliers will hardly damage a retaining ring.

However, to use retaining ring pliers effectively, you must pick the proper size. Snap ring pliers are sized based on the size of the ring fastener and the gap between the open ends.

Also, the tips of snap ring pliers must be the correct size because they must fit onto the lug holes of the ring fasteners. If the tips are too broad they won’t fit and if they are too small, the ring will easily snap out.

Therefore, if you know the size of the grip holes on the snap rings, you can easily find the most appropriate size of snap ring pliers tips. It is even better if your snap ring pliers have removable tips because you can easily install the tips with the right diameter to fit the grip holes.

Despite the retaining rings being small they are very strong and create a lot of stress on the retaining ring pliers. Hence it is advisable to use pliers that are strong enough to withstand the stress. These are some of the strongest snap ring pliers sets in the market for both external and internal snap rings.

In a nutshell, snap ring pliers can save you a lot of valuable time when working on assemblies that utilize snap rings. And since sometimes you may not know whether you will come across these lock rings, it is just good to have a pair of snap ring pliers at hand if not a set.

2. Linesman’s pliers or Combination Pliers

Linesman’s pliers are a type of ordinary pliers for gripping, twisting, straightening, bending, and cutting wires, cables, and other materials. They are also known as electrician’s pliers or combination pliers at times.

However, linesmans are subtly different from the actual combination pliers. Read this article [combination pliers vs linesman pliers] to understand these two types of pliers.

The effectiveness of the linesman’s pliers is attributed to their design. They have a flat gripping surface at the end of their snub nose. The rest of the jaw has horizontal grooves that provide a firm grip on objects.

Linesman pliers also have a large cutting edge for cutting wires and cables and other materials. They are a handy tool for cutting wires, especially when you don’t have a pair of side cutters at hand. I often use them along with my Klein dykes whenever I am working on a vehicle’s wiring system.

The best linesman pliers are made from forged steel for strength and durability. Their handles are hot riveted to maintain accuracy even after repeated use. There is a variety of handle types to choose from but the comfort grip handles are the most suitable for a mechanic.

But if you were working around high electrical voltages, it is safer to use linesman pliers with insulated handles.

Some linesman’s pliers have extra features such as a universal crimper for pressing wire crimps and ferrules. Others have a gripping zone behind the joints for pulling wires. You may want to consider these extra features when selecting the best linesman pliers for automotive applications.

3. Locking pliers

Locking pliers or vise grips are spring-loaded pliers that can be locked into position, actually giving you an extra pair of hands to allow you complete your task.

These pliers are great in the sense that they offer superb clamping ability hence ensuring a tight grip to keep things just where they need to be. You can use them when you need more torque to remove or turn an object. Another instance where you may find locking pliers really useful is when you need something to clamp objects together.

Common uses for locking pliers in the automotive industry include clamping, holding, pulling staples and other fasteners, extracting stripped nuts and bolts, wire cutting, shaping tasks, and other tasks that involve pressing and squeezing.

Lastly, locking pliers come in various sizes, shapes, and types. You can choose the most appropriate depending on the nature of car repairs for which you are using them. The good thing about them is that they are versatile and adaptable. You can use them for a variety of jobs from the smallest of tasks to bigger tasks.

Types of locking pliers include

  1. C-clamp locking pliers – these are characterized by long angled arms that form a point. These pliers when locked form the shape C in order to clamp around girthier objects.
  2. Round nose pliers – these are curved like a bird’s beak and have teeth within their inner sides of the jaws. these are ideal and mostly used on rounded objects and surfaces.
  3. Long nose locking pliers – these are formed like a pair of needle-nose pliers. They have teeth within their inner sides of the jaws. they are used and work well on flat surfaces.
  4. Curved jaw locking pliers – these are round nosed and have serrated teeth inside the jaw to help clamp onto rounded objects.
  5. Straight jaw locking pliers – these are either round or long nose. Most long nose locking jaws are straight jaw while round nose pliers are either straight or curved.

4. Hose clamp pliers

Hose clamp pliers are for removing or applying hose spring clamps onto or from rubber hoses. Spring clamps are made of spring steel and are plated with zinc to prevent rust and corrosion. They are common in the auto industry because of their constant tension which they apply on high-pressure rubber hoses. You will find them under the hood of a car on radiator hoses, fuel lines, and ATF hoses.

However, just the same way the clamps are strong on the hoses, they are not easy to install or remove without a proper tool. That is why you need the spring hose clamp pliers.

Spring hose clamp pliers provide a tough grip on different types of hose clamps. They have specially designed jaws and teeth. The jaws have rotating tips with grooves for handling various types of clamps. You can rotate the tips to match their teeth with the thickness of the hose clamp you are working on. Whether it is a wire clamp or band clamp, these pliers are ready for the job. You can even use them for various types of spring band hose clamps including the standard clamps, space-saving clamps, and flat type clamps.

Once you start using the hose clip pliers, you will be surprised how easy they make the work of gripping and moving the spring clamps. They are a great time saver and not to mention that they also protect your knuckles while working with spring clips.

5. Drum brake spring pliers

Drum brake pliers are a very important tool in the automotive industry. They are designed specifically for handling, removing, and replacing the springs found in drum brakes.

Unlike disk brakes, drum brakes can be intimidating to work on. If you have ever worked on a drum brake system, I bet you understand what I mean. There is a handful of springs and they seem interconnected. Without a proper tool, the springs can fly all over when you attempt to remove them. And getting them back in position is not that easy. That is where the brake spring pliers come in handy.

The tip of one of the jaws of the brake spring pliers is rounded to remove the springs while the other is curved to put the springs back. Additionally, one of the handles may have a ratchet to help in separating the shoe hold-down pin.

Good drum brake pliers are made from hardened heavy-duty steel for added strength and durability. They can also be coated to prevent rust when you store them in the toolbox or pliers drawer.

6. Oil filter pliers

Oil filer pliers are used in the automotive industry to remove stuck oil filter housing when changing oil. The pliers are asymmetrical in design. They feature c-shaped pair of toothed jaws with one of the jaws being much longer than the other one. This configuration helps clamp down on the stubborn oil filters to dislodge them from the stud without slippage.

The best oil filter removal pliers are made from special tool steel for maximum strength. They also have insulated handles and toughened teeth to prevent slips on the filter canister.

Although oil filter canisters should be easy to remove by hand, sometimes they get stuck. Others are deeply seated and may not be easy to reach by hand. That is why you need these handy filter removal pliers close by. They are suitable for hard-to-reach filter housings and oil filters that are too tight to remove by hand. Nonetheless, you should avoid using any tool to tighten oil filters in cars. A hand-tight filter should be just fine.

7. Pliers wrench

Instead of buying an adjustable spanner, I would suggest that you get a good pair of pliers wrench instead. More specifically, I recommend a 10-inch or 12-inch knipex pliers wrench. And if your budget allows, you can include either the pliers wrench xs or the 5″ mini pliers wrench for working on small bolts and nuts. They are also good EDC pliers for carrying around.

The reason I recommend the Knipex pliers wrenches is because they are the best option as of now. They are very well built, grip fasteners tightly, and have an integrated ratcheting function. The ratcheting action allows you to use them on fasteners in confined spaces where you will only get a small swing arc.

Knipex pliers wrenches are also easy to adjust and will remain set until you change them manually. These features make them more effective and convenient than an adjustable spanner or a set of box wrenches.


The are so many types of pliers you can keep in your garage for auto repairs. But in my opinion, these are the most essential automotive pliers every car garage should have.
