Radiator Repair Techniques
Below provides three methods that you can do in order to repair a plastic radiator if the damage to it is not wide-ranging and extensive.
- Using a soldering iron gun that will melt the plastic and seal the leak.
- Using an epoxy that will melt after sometime to seal the leak.
- You may use both methods, solder the leak and then apply epoxy.
The first method of using a soldering iron gun can be done quickly and save on costs, especially if you already have such an item in your possession. However, the second method of using epoxy is also very easy and inexpensive. The third option of using both methods is considered an ideal one, as it will last longer compared to the other two methods.
The aforementioned techniques are simple. They require only basic skills, a soldering iron gun, and/or epoxy. Both items can be found in online stores such as Amazon and Ebay or in any hardware/tools store.
Soldering Method for Fixing Plastic Radiator
After the cleaning of the area that is leaking, it is time to use a soldering iron gun. Hold the soldering iron gun approximately one inch away from the leak paying close attention not to over expose the area to excessive melting. The iron will melt the plastic and force it to combine together and seal the crack. The timing, and to what extent the plastic needs melting, all depends on the size of the crack. If it is big, then more plastic melting will be required. After you are done with sealing the crack you can put water or any other liquid on the area in order to know if the problem still exists.
Epoxy Method for Fixing Plastic Radiator
Usually, epoxy is applied on the leakage in order to make the seal strong enough and to increase its life.
Epoxy is a common method used for repairing a plastic radiator. Epoxy is a combination of chemicals that, when applied, increases temperature and melts the plastic of the radiator. With the help of epoxy you can add extra material on the crack that would be helpful if your radiator walls are thin. You can easily mix the ingredients that are included in the radiator repair kit easily.
Most radiator cracks are easy to fix and will not take much time to repair.
