Aluminum radiators are a common type of radiator used in many automobiles and other vehicles. While they are durable and efficient, they can develop leaks over time. Luckily, fixing a leaking aluminum radiator is a relatively easy task that can be completed with a few tools and supplies.
If your aluminum radiator has a leak, you will need to replace it.
Can aluminum radiator be repaired?
If your radiator is made of aluminum, you cannot repair it like you would a copper-brass radiator. Additionally, the type of tanks and the location of the leak is important too. Let’s review a few preliminary steps you need to take before you do anything else.
The dremel tool is used to clean the part and the super alloy one rod is used to flux the part.
How do you fix a pinhole leak in an aluminum radiator
If your radiator is leaking, you’ll need to drain it and then clean the surface around the holes so that the epoxy bonds to the radiator. Apply the epoxy to the holes according to the manufacturer’s instructions and allow to dry thoroughly. Once dry, you can then refill the radiator and the leak should hopefully have stopped.
If you’re soldering two electrical wires together, use electrical solder (electrical solder has a rosin-core flux). For a non-electrical item, such as a radiator, use acid-core solder (this contains an acid flux).
Can I JB Weld my radiator?
J-B is a great company that produces high quality products that are versatile and dependable. Their products are great for radiators, washer fluid tanks, storage tanks, water tanks, plastics, composites, PVC and more. Professionals, mechanics and avid DIYers know that J-B gets the job done right. There is no project too big or too small for J-B, they have all the products you need to get the job done right.
JB Weld is not a permanent fix for an aluminum radiator. It is a temporary solution that will stop the leak until you can get the radiator to a repair shop.
Which JB Weld is best for aluminum?
This epoxy cold weld system is perfect for repairing surfaces that are difficult to bond, such as aluminum, metal, composites, and fiberglass. It provides a strong, lasting bond that will keep your repairs looking great for years to come.
J-B Weld is the perfect aluminum welding solution. It is to be mixed with alcohol that acts as a thinner. This mixture than has to be poured into the damaged areas of the radiator. The welded area then has to be heated with the help of a hair dryer.
Is aluminium easy to repair
When attempting to repair a large dent in aluminium, it is important to be careful not to overstretch the metal. Work from the outside of the dent towards the center, so as to gradually reduce the size of the dent. With a little care and patience, aluminium dents can be repaired just as easily as steel ones.
Thank you for your question! We do not recommend using Flex Seal on surfaces where it comes in direct contact with drinking water, as it is not made to withstand extreme heat or pressure.
What can I use to patch aluminum?
Both epoxy and tape can be used to effectively repair small holes in metal surfaces. Specialty epoxy and tape products are available that are designed specifically for patching steel and metal. When choosing between the two options, consider the size and location of the hole, as well as the type of metal being repaired.
I used Radiator Weld to repair a crack in my radiator. I followed the instructions on the package, and it worked great! I would definitely recommend this product.
Do you need a special solder for aluminum
If you’re soldering aluminum, you need to use an aluminum soldering flux. This is because a flux that is strong enough to solder an alloy like stainless steel won’t necessarily work on aluminum. Aluminum soldering flux is specifically formulated to work with aluminum, so it’s the best choice for this job.
Abrasion and reaction soldering are more commonly used with aluminum than with other metals. However, aluminum requires special fluxes. Rosin fluxes are not satisfactory.
Is aluminum difficult to solder?
Soldering to aluminum is extremely difficult and requires a completely different process than soldering to copper or solder coated surfaces. The issue with aluminum is the oxide layer that forms on the surface of the aluminum. This oxide layer needs to be removed in order for the solder to make a strong bond with the aluminum.
J-B Weld ExtremeHeat is ideal for repairing orfabricating metal components that will be exposed to high temperatures. Once fully cured, it can be machined or sanded just like any other metal. This makes it a great choice for repairing or creating metal parts that will be subjected to extreme heat.
Does J-B Weld hold up to heat
J-B Weld is a water-resistant, petroleum/chemical-resistant (when hardened), and acid-resistant epoxy adhesive. It also resists shock, vibration, and extreme temperature fluctuations. J-B Weld can withstand a constant temperature of 500 °F (260 °C), and the maximum temperature threshold is approximately 600 °F (316 °C) for 10 minutes.
This product is amazing! It worked instantly to fix my gas tank and radiator. Super Glue Pro Seal N62020 is the best product I have ever used.

If your aluminum radiator is leaking, you will need to take it to a professional to have it fixed. If it is not leaking, but you notice that it is not working as well as it used to, you can try cleaning it yourself. First, remove any debris or dirt from the surface of the radiator. Next, use a mild soap and water to clean the radiator, being careful not to damage the aluminum. Finally, rinse the radiator off with clean water and dry it with a soft cloth.
A aluminum radiator can be fixed by using a soldering iron to weld the cracks together. However, it is important to make sure that the radiator is clean and free of any dirt or debris before attempting to weld it.
