How to Use a Grease Gun on a Car (Step by Step Guide 2022)

The use of a grease gun makes it relatively easy for you to lubricate or easily apply grease on your car where needed. It is a lightweight tool that is efficient for automotive and other lubrication purposes. The device is best used on vehicles instead of squeezing grease out of a tube manually. The only challenge is how to use a grease gun on a car for an effective result?

The right way to use a grease gun is to get the proper grease, the right gun, load the gun with the grease, and prepare the point of application before you use it on your car. You must know the two ways of loading the gun with grease. You can either load with a cartridge or without a cartridge.

So, on this page, you will get to know more about using a grease gun on a car and the correct application.

How To Use A Grease Gun On A Car?

First, you need to load the grease gun, prepare the application area, and then apply the grease. You can only use a grease gun by loading it with the proper grease through two methods. The two methods are different, and you can simply use any of them to achieve your goal.

Therefore, below we have the two methods you can use to load the grease gun. But before then, how well do you know your grease gun?

Getting Familiar With The Grease Gun

You must know the grease gun very well. Getting familiar with the grease gun will help you find it easy to handle and operate the tool.

Getting Familiar With The Grease Gun

  • Lever: the level on the grease gun is the part that controls the role of hand pumping the grease from the barrel into the hose or applicator tube
  • Barrel: it is the housing for the grease tube or the grease, depending on the type of grease gun you have
  • Grease tube: it only comes with a grease gun that has a cartridge
  • Hydraulic coupler: it is the connection point of the grease gun, and it helps to hold the hose or tube to the head of the grease gun
  • Filler nipple: the filler nipple is the injection point in the filler pump for the grease
  • Plunger: this provides the right amount of pressure to the back end of the grease to get it out of the application opening
  • Follower rod: it is also known as the barrel rod, piston rod, and plunger rod. It helps to keep pressure to the bottom of the grease tube to make it easy to insert a grease tube and push the grease.

Loading Your Grease Gun With A Cartridge

Loading Your Grease Gun With A Cartridge

  • You should get the barrel and unscrew the head from it
  • Then you should pull the rod handle on the gun and ensure you do until you can’t pull any longer
  • You should then lock the handle
  • Remove the plastic cap that comes with the new cartridge you got and insert it into the gun. You should ensure the bottom goes in first into the gun
  • Then you can go ahead to open the cartridge by removing the metal tab
  • Get the grease gun head back to its position, and you need to be sure it is tight to avoid any form of air escaping
  • Now you can lock the rod handle and gently push the rod into the grease gun
  • To complete the task, you need to tighten the grease gun head. You can then go ahead to pump the gun until you notice the grease flowing out of the head, and then you can start greasing on your car.

Loading Your Grease Gun Without A Cartridge

The second option of loading your grease gun is without a cartridge, and the instruction below will help you through without hassles.

Loading Your Grease Gun Without A Cartridge

You need all essential items to load your grease gun, and they include a non-cartridge grease gun, a container filled with grease, and a clean piece of towel or dust-free cloth.

Get The Grease In The Barrel

You need to unscrew the head of the grease gun from the cap. The process will help you confirm that the piston rod you have inside the barrel is well depilated as it will make it easy for you to suck grease using the gun

Pull The Plunger

Once you complete the step above, you can insert the distal end of the barrel into the container where you have the lubricant and keep it down. You should then gently pull the plunger rod to get the grease into the barrel. Take note that you should have the grease in the container for it to work properly

Get The Barrel Out

Once you are sure the barrel is filled with grease, you should pull it out from the container. You should expect to see some grease around the barrel, and you can keep it clean using your towel or dust-free cloth to wipe off the excess grease or lubricant

Apply The Grease

You need to screw back the cap on the barrel head and press the piston rod handle until you notice the grease from the applicator tube. You can then apply to the areas where you need grease on your car.

Why Does My Grease Gun Not Work?

You should not work yourself out because your grease gun is not working, even if you just got the tool. There are many reasons the grease gun will not work properly as it should. Knowing why it fails to work will help you know how to fix the grease gun.

Why Does My Grease Gun Not Work

Air In The Grease Pump

One of the major problems you face with new grease guns is that they do have air in the pump. Once there is air in the grease gun passage, it will be quite hard to get the grease gun to work properly. You need to bleed the grease gun by purging the air from the passage.

To get the air out, you need to twitch the base of the grease gun many times by turning it anti-clockwise. While rotating the base, you should pump the grease gun, and the air in the gun will find its way out. You should turn the base clockwise to seal, and then you will notice the grease will come out from the tube.

Faulty Grease Gun Spring

If the spring in the grease gun is faulty, it will be quite hard for you to carry out any successful greasing task on your car. One of the ways you can get to know the fault is from the spring is when you have the cartridge filled with grease, and it is not coming out.

The fault might be a reason for loose spring, and the impact or pressure to power the chamber with the coupler will be minimal. To fix this issue, you need to get a new gun spring. You can always get it from any local store or online stores such as Walmart and Amazon.

Faulty Piston Rod

A faulty piston rod is not a common issue with a grease gun but one that can affect the productivity of the tool. It occurs mostly with old or aged grease guns due to corrosion and rust buildup in the piston rod. Getting a new one and replacing it with the old piston rod is the right thing to do.

Failed Gun Plunger

Once you experience a stiff plunger, the grease gun will not operate properly. The plunger feeds the grease to the chamber, and it has to be flexible to do the task effectively. One of the reasons is that the plunger gets expanded. You just need to find a better replacement.

If your grease gun fails to operate in the right way, you need to check for any of the problems mentioned earlier. You can easily fix some issues by getting a replacement, and some will require that you get a new grease gun.

Types Of Grease Gun

If you are getting a grease gun for lubrication or any automotive project, you should know the types of grease guns you can come across in the market. There are different grease guns, and getting to know them with their application will help you choose the right one for your task.

1. Pneumatic Grease Gun

One of the grease guns you can consider is the pneumatic grease gun. It has other names such as air pressure grease gun or pneumatic grease pump. The operation of this grease gun involves using an external air compressor such as RoofPax Air Compressor to force the grease out of the tube.

Pneumatic Grease Gun

The pressure from the compressor passes through the hose or airline that is attached to the tool. Once the pressure applies the force, the grease will come out easily through the outlet nozzle to the hearing void or grease nipple.

In addition, this grease gun is the perfect option for a large task as it helps to handle any greasing work at a faster rate. All thanks to the air pressure higher than the one you generate using a hand or manual pump.

2. Manual Grease Gun

One of the options you have with a grease gun is the manual grease gun. It is easy to use compared to a pneumatic grease pump. Most people love to use it, especially Macnaught K32 Pistol Grip Grease Gun because it is simple and efficient. Depending on external tools before you can grease any car can delay your task.

Manual Grease Gun

Also, people do call it a lever grease gun. You can operate the grease gun by squeezing the handle or the piston to keep a close tab on the grease flow through the nozzle. With this grease pump, you are in charge of determining the grease level that will come out from the nozzle.

The force you apply to the squeezing determines the level at which the grease will come out of the bearing. Therefore, you are in control of what comes out of the tool.

3. Electric Grease Gun

The Makita XPG01Z 18V LXT Lithium-Ion Grease Gun is a better option to consider for a greasing task if you are going for an electric grease gun. The gun makes use of a powerful motor to dispense grease. For you to grease using this method, you need to have an uninterrupted power source.

Electric Grease Gun

Battery grease gun Lumax LX-1175 Handyluber 12V Cordless Grease Gun makes a good fit for any greasing task you have on your car. It is one of the quality battery grease guns to consider. For battery grease guns, they operate just the same way as the electric grease gun. The difference is that the battery grease guns are cordless while the electric grease gun is corded.

Frequently Asked Questions

What Is The Highest-Pressure Grease Gun?

The highest-pressure grease gun can deliver within the range of 3000 to 15000 psi. You shouldn’t apply too much pressure when greasing as you can easily damage the bearing seals. Also, according to Sae, the GUN-HP2 is the American made grease gun with the ability to deliver 15000 psi. It is best for dispensing high viscous lubricants.

How Much Grease Do You Put In A Grease Fitting?
