Spotting the problem in cracked radiator
It is important for your radiator to be checked regularly if you want it to last. You should identify any potential problems because these are easily spotted by looking at the exterior of the unit and checking all its components.
You should check all the fittings, pipes and plates. If you notice any cracks on these parts of your radiator then it is likely that this has already caused damage internally to its core system. You should repair plastic radiator with epoxy as soon as possible before it gets worse or causes further damages.
How to find problems in a cracked radiator yourself: step by step
If you are on the hunt for potential problems with your radiator, then there are a few steps that will help to narrow down which one it might be.
- Check all fittings and pipes: if these have any cracks or holes in them then they should not be used until they have been repaired. This is how water can leak out of your radiator system when this happens so make sure to take care of it as soon as possible before further damage occurs.
- Locate where the problem is coming from: If you notice that only certain parts of your unit has cracks while others remain intact then you know what part needs repair work done thanks to its location in relation to other elements of the cooling system.
- Spot signs of water leaks: a radiator with cracks can cause water to leak out, so if there are any wet spots on the floor then this is likely where your problem started from.

How to fix cracked plastic radiators step by step
If you have noticed that one of your fittings or pipes has developed problems and needs repair work done, then here’s how to do it. First take off all traces of heat insulation before using epoxy glue as an adhesive for replacement parts when fixing cracked plastics and make sure not to touch anything until everything dries! Then, you can use a putty knife to remove any old or loose parts and clean the area, using denatured alcohol on a rag to soak up all grease.
Step by step instruction:
- Remove All Remaining Heat Insulation
- Use Epoxy Glue as an Adhesive
- Clean Area with Denatured Alcohol On Rag
- Use Putty Knife to Remove Old or Loose Parts and Clean
- Let Dry Completely Before Using Heat Source Again!
What glue is suitable for repairing a cracked plastic radiator
Epoxy is a good adhesive for repairing a cracked plastic radiator.
It has the advantage of being waterproof, strong and easy to use. This ensures that it can’t leak out between the cracks in your radiator and onto other surfaces below. It’s important that you always read the instructions carefully before starting.
The two parts epoxy are mixed together thoroughly until a thick cream forms, then applied to both sides of crack or hole in the plastic radiator with enough space on each side so they don’t overlap when dried . You need to make sure you cover any metal clips as well – these will corrode if left exposed while drying . To speed up this process some people recommend using an electric heater but be aware that doing so may increase chances of cracking nearby joints which have not been clamped.
The use of silicon sealant for repairing radiator cracks can also be effective if done correctly, but it does take longer for the sealant to dry completely before water can leak through again. It may also require periodic maintenance or replacement every year due to the eventual breakdown of rubber seals from continuous exposure.
How to fix cracked plastic radiator with epoxy: full instruction
- First step is to clean the radiator. Pour water over it and use a scrubbing brush to remove any dirt or rust stains that may be sitting on top of the surface, then rinse off with clean water.
- Next, use a damp cloth to wipe off any excess water.
- Apply epoxy to the radiator in small sections at a time and let it dry for about 15 minutes before applying another coat of epoxy over top. Work your way all around the exterior surface of the plastic radiator until you have covered every inch with epoxy. Be sure not to put too much pressure on or scratch up against the plastic when pushing out air bubbles that may form. Wait an additional 24 hours after you’ve applied one final layer before putting back into place.
- To protect from future damage caused by accidents or wear, apply vinyl sheeting overtop as well.
