How to Remove Crimp Hose Clamps and Radiator Hose Clamps

Are you looking for an in-depth guide to know how to remove crimp hose clamps? Welcome then, this guide is for you!

Crimp hose clamps are made for single-time use since the clamp crimping deforms it completely. In easy words, when removing the clamp, it will get destroyed; without destroying it, you won’t be able to remove it. And if, in any case, you even remove it without damaging it, that is not suitable for reuse.

Because of the single-use, they are used in components that are not changed frequently. However, let’s not make the intro much bigger and get down to the actual business. Not only crimp hose clamp, but we have also shown exact ways to remove radiator hose clamp as well.

Let’s get started then!

Removing a crimp hose clamp is not a tough job; all you need is the right direction, which we are providing you. Go through the guide first, understand, and then start the process.

Items You Are Going to Need:

  • A Diagonal Cutter
  • Hose Clamp (Screw Type)
  • Nut driver or Screw Driver (Flat Head)


The very first thing you need to do is depressurize the hose you are looking forward to disconnecting. Not in case of removing hose clamp, before doing anything, you need to make sure that component is not functioning. However, after depressurizing the hose, find out the crimped ear.


Now pick your diagonal cutter, as we mentioned above. And with that, you have to snip the crimped ear from the clamp. After that, there will be some clamp remnants, and for peeling those off, you can use any cutter. However, be very careful when doing these things, you do not want to damage the hose pipe. Be careful with the diagonal cutter while peeling remnants, finger cuts often happens when the cutter is not used wisely.


You have already removed the hose clamp, and now it is time to install a new one. As we said, pick a new screw-type hose clamp, and now we are going to install that on the hose. So for your comfort, rotate the clamp and keep it in an angle for where you can access the screw very easily.

Once you have done that, pick the screwdriver set and choose the suitable screwdriver from the set or nut driver and tighten the hose carefully. A mistake that a lot of beginners do is they overtighten the screw, which damages the hose. Not only that, because of over-tightening the screw strips out which makes the clamp completely useless.

Some Advanced Tips

  • When you are removing the clamp with cutters and all, make sure you take proper precautions. The items needed to do the process are dangerous, and any wrong turn can damage both you and the hose pipe. So be very careful.
  • As we said, use screw-type clamps. But when it comes to high-pressure hoses such as A/C, Power steering, etc. You should not use screw-type clamps.

4 Steps to Remove Radiator Hose Clamp Easily

After the crimp hose clamp removal, we are heading towards another guide, which is how to remove radiator hose clamp. When you are looking forward to repairing a radiator hose, then knowing radiator hose clamp removal is a must. There are different types of radiator hose clamps, which you might not have seen earlier. The most important thing about radiator hose clamp removal is knowing the clamp types. However, let’s get down to the actual business.

1. Knowing the Clamp

The very first thing you have to do is, try to know the clamp. As we said, there are different kinds of clamps. Take a look at the clamp, which is attached to the hose. If you see the clamp has a screw that means, you have a band clamp or crimping clamp.

You have to unscrew the band clamps to release the hose, removing that entirely isn’t necessary. You don’t have to unscrew completely, loosen the screw, and it will be easy to remove.

On the other hand, if you have a crimping clamp, then you have to remove the hose first and then remove the clamp.

2. Remove the Coolant

One essential thing that you should remember. Before you start the hose clamp removing process, make sure you empty the radiator of antifreeze or coolant. Do you know how to do it? Wait, we are telling you the way.

Take a bucket or a tray and put that under the radiator. And then pick a wrench and open the petcock with that when you open the petcock that will drain the radiator. Ensure that the radiator is empty. And when the work is done, properly lock the petcock.

3. Unscrew the Band Clamp

Now time to take the band clamp off! Pick the screwdriver and put the tip of that into the screw and rotate counterclockwise. That will depend on the position, so you have to sort that out. However, slowly unscrew the clamp and check is it getting loose or not. That’s all when you feel that the clamp is completely loose, remove that. And remember, when you are attaching a new clamp, make sure you do not tighten the clamp much.

4. Remove the Crimping Clamp

If you have a crimping clamp, then the process is different, not the same as the band clamp. Hold the two bars (vertical bars of the clamp) closed. And you are going to need pliers. Squeeze both clamps together very tightly, and that will enable you to turn the clamp. And then you can loosen the screws holding the clamp with the hose. The rest is the same as the band clamps. Slowly remove the hose from the clamp.


That’s all! By now, you should have learned how to remove crimp hose clamps. Along with the crimp hose clamp removal, we have shown how to remove radiator clamps as well.
