How To Unseize Coilovers


When dealing with cars that use coilover suspension, it is important to know how to unseize them! This article will explain what coilovers are, how they work, and some easy ways to do this for different makes and models.

You can choose to remove the spring or the damper of your car’s coilover system. There are several reasons why you would want to do this, but all boil down to one thing: control.

Control comes in two main forms: going faster or slowing down. The more control you have over your vehicle’s speed, the safer you will be behind the wheel. Similarly, being able to slow yourself down gives you another layer of protection because you won’t be hurtling towards something at high speeds.

This article will talk about removing the springs from a stock coilover setup and doing the same thing to firm-mounted dampers.

Use penetrating oil

When performing any type of wheel modification, making sure your hands are clean is a very important part! If you’re working with metal or plastic, it is crucial that you wash your hands thoroughly before touching anything else.

When altering vehicle suspension components such as shocks or coilover units, there is always some sort of lubricant used to ease friction during operation. Most times this is done via either using grease or petroleum products.

However, not all greases and oils work well when changing up your car’s suspensions. Some types of oils can actually cause damage to the springs, bushings, and other parts of the system.

There are many different types of oils out there, so make sure to do some research and find one that is appropriate for your cars modifications!

Our favorite oil to use in this case is silicon-based spray paint thinner. It will easily penetrate the coils and bushes of your new dampers, removing most if not all residue. Also, it is totally safe to apply onto exposed surfaces like shock towers and bolts.

Thoroughly rinse off the modified parts to ensure no leftover debris has dried in the rings and seals, and then wipe them down with an alcohol-soaked rag to remove any moisture.

Use a heat gun

The next tool in your arsenal is a good quality heat gun. These are very useful for doing small jobs that require heating up or cooling down of materials. They are usually hand held and can be used to apply thermal paste, warm or cold liquids onto components, and even melt solid solder!

Heat guns work by using electricity to transmit energy into the surface of the component being worked with, thus altering the behavior of the material. This may mean melting something away, changing the shape or temperature of an element, or otherwise modifying the component’s function.

By having a good working knowledge of how different types of coilover dampers behave when pressed together or spread apart, you can use the power of the heat gun to modify their functionality. If there is no information available about what sort of coilover you need to work on, simply searching online will likely turn up some helpful resources and tips.

Something important to remember while using a heat gun is to never apply any electrical current directly to either metal or plastic, only gel thermal pastes or liquid coolants should be used.

Use a blowtorch

The next tool in your arsenal if you cannot get your coilover off is using a low-heat, steady stream of air flow from a hairdryer or other source to evaporate any leftover adhesive.

Alternatively, you can use a good quality blow torch to burn away the glue. Make sure to wear protective goggles as well as heavy leather gloves to prevent any hot wax burning yourself!

Be careful not to over heat the coils or melt the spring, they will both break down and fail soon after that happens.

Use vice grips

The next tool you will need is something called a “vice grip” or more commonly known as a car puller. These are designed to easily lift heavy objects away from your vehicle.

You can get these at any automotive parts store, but make sure they are high quality brands that are sold directly from their site.

These tools cost around $20-30 depending on size and model, so they were definitely worth it!

Once you have yours, you will want to pick out whichever part of your coilover system you would like to use them on. To do this, you will firstly need to remove the spring seat covers. You then slide the lever off the top and under the body before lifting up the air compressor bag.

Then, using the puller, drag the part down towards you until it releases.

Use WD-40

A very popular way to remove stubborn stuck parts is using oil or petroleum products as a solvent. If you use the right amount, it will work as soon as possible!

One of these oils that works well is called WD-40. This chemical was originally designed for engine maintenance, but people have since found many other ways to apply it. It can be applied directly onto the stick part in order to break down the glue or adhesive that is holding it together.

WD-40 has an extremely low risk of poisoning due to its limited toxicity and length of exposure. It is not harmful when used correctly. When applying this product, make sure to wash your hands immediately after being exposed to avoid any kind of irritation or skin problems.

General tips: try rubbing the affected area with clean, smooth surfaces before dipping into the liquid.

Use anti-seize

When performing maintenance or changing out parts, make sure you use the correct tools! If your car has coilover shocks, there are two main components that can be replaced. The spring and the damper are called the springs.

The spring is what compresses when the vehicle comes down off of a hump or uphill slope. It takes energy away from driving by releasing it back into space. The damper is how fast the spring moves as it releases this energy.

If these parts get too tight or dry, cars will need more gas pedal pressure to move the same amount of air which affects handling and safety. This could also cause damage to the engine due to lack of power needed for fuel combustion.

To change out either part, you’ll first have to loosen up the old one before installing the new one. Using the wrong tool can hurt way worse than doing nothing at all!

Many people use steel wool to soak up any glue left over from attaching the old component. However, copper powder can be used instead since it removes both corrosion and glues.

Use automotive glue

When performing any kind of wheel modification, it is important to know what tools you have access to. If you do not, then chances are your modifications will be limited.

One tool that many people don’t use but should is automotive glue. Glue can help hold wheels onto cars even more than using screws or bolts! Depending on the type of glu, these bonds can last hours, days, or even weeks before being worked on.

A common way to use this product is to take two thin coats between each other and apply it where the wheel meets the car. This helps prevent bubbles as well as cracks in the clear coat due to stress from moving parts.

Use a hammer and punch

If you are ever stuck removing your coilover dampeners or replacing them, there is an easy solution! All you need is a small metal tool called a hammerer’s punch. A normal length wooden handle with a slightly rounded end used for striking metals will work just fine.

All you have to do is hit the spring hard enough so that it breaks off at the connecting rod, then pull the whole thing out. The hardest part may be getting the old one away if it has dried down.
