- Allow the engine to run for 5-10 minutes while the stop leak product makes its way through the coolant system.
- After running it, allow the engine to sit overnight as the sealant sets.
What kind of solder do you use to fix a radiator?
acid-core solderThere are two types of solder you'll be using -- electrical solder and non-electrical solder. 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 radiator, use acid-core solder (this contains a acid flux).

What is brazing a radiator?
The radiator pipes and fins are joined by brazing, a method of joining metal components using a melted filler metal. There are many metal types used as the brazing filler metal, but they need to have a lower melting point than the base material to ensure that the components are not damaged during the brazing process.
Can you repair a radiator leak?
If it seems to be coming from a loose clamp, you can simply tighten it to stop the leak. And if it's coming from a radiator hose, you can replace it. But if it's clear the leak is in the radiator itself, you can typically fix it within minutes.

Before
Breaking the oxide coating by agitation and fluxing is one key to successful soldering, especially for Aluminum, Stainless Steel and Nickel plated parts. It is important to follow these steps in a timely uninterrupted 1-2-3… sequence. Otherwise, the strong oxide coating can reform and hinder the solder bond.
Pre-Tinning
For some difficult to solder and large surface area joints, it may be extremely helpful to pre-tin the joint area on each part with the solder before setting up to join the parts. Simply follow the steps below to coat the joint area of each part with an even coat of solder.
Step 1
Pre-clean the parent metal or metals to be joined. Use emery cloth, a wire brush, sandblasting, etc. Prepare Aluminum and Stainless Steel surfaces with a stainless steel wire brush. For delicate tubes and parts on radiators and heat exchangers, this physical agitation may not be possible.
Step 2
Apply the Kapp Golden Flux to both parts to break the oxide layer and draw the solder into the joint/repair area. You may easily use the rod to spread the flux. Step 3 Use a soft flame, heat gun or soldering iron to heat the parent metal adjacent to the repair area.
Step 4
Hold the torch tip 4 to 6 inches away from the parent metal. If it is necessary to apply the flame directly to the rod or flux, pull the torch tip back even farther from the work surface and keep it moving.
Step 5
The flux will begin to bubble and turn light brown. Besides preparing the parent metal for the solder, these changes indicate the proper flux working temperature. If the flux turns black, it will contaminate your joint and prevent a strong bond. In that case, let the area cool, clean it & start over.
Step 6
When the flux turns brown, it is time to apply the rod. Drag the rod over the area to be soldered, until it begins to flow. ONCE THE ROD FLOWS, STOP APPLYING THE HEAT! If additional layers are needed, continue to drag the rod over the area.
Can you use solder to repair a radiator?
All radiator soldering is safe. There are really no conditions that make it unsafe to solder your radiator. If the vehicle is quite old and the radiator is falling apart, there is very little chance that soldering will help matters.
What is used for radiator repairing?
You should know that the most popular—and easiest—way to fix a radiator leak is to use a stop-leak product that you simply pour into the radiator. For example, AlumAseal Radiator Stop Leak & Conditioner can quickly fill any small holes in the cooling system.
Can you use solder on aluminum radiator?
Aluminum radiator repair is not as easy as repairing a copper brass radiator. Most copper and brass radiators just need a clean surface and some solder to repair. Aluminum radiators can utilize a thinner core, with wider tubes, allowing for better air and coolant flow through the radiator.
What is the best way to fix a hole in a radiator?
You’ll need to drain the radiator and then clean the the surface around the holes so that the epoxy bonds to the rad. 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.
Do you need flux to solder aluminum?
You’ll find out that you can solder aluminum. The Right Flux: You need an aluminum soldering flux – a flux that is specifically formulated for soldering aluminum. Just because a flux is strong enough to solder an alloy like stainless steel doesn’t mean it’ll work on aluminum.
Can you repair a radiator with epoxy?
Yes, radiator epoxy or cold weld epoxy is effective in repairing a leak. However, this is not a lasting solution. You fix a radiator leak yourself and it should hold for a while, but it is recommended you get a replacement as soon as possible.
Can You Use Flex Seal on a radiator?
Can I use Flex Seal to stop a radiator leak? No. Flex Seal is not made to handle the pressure of a coolant system.
What to use to clean brass before soldering?

Is sandblasting a good way to get metal down?
780. Yes, CLEAN is the key. Sandblasting is my favorite way to get down to real metal, provided you have no water in your air. Also a good suggestion to disassemble seams to allow thorough cleaning, or else gunk in the seam next to the leak will prevent you from getting a good repair of a small split.
