Can Radiators With Plastic End Be Repaired

If your car radiator has a small leak, you may be wondering if it is possible to repair a plastic radiator and fix a radiator leak. Afterall, in that location is high-pressure, high-temperature coolant in the radiator tank. You may ask yourself, "How can a radiator epoxy agglutinative possibly concur up under those conditions?" The respond is that it probably can't. It may fix the radiator leak temporarily, simply over time, the radiator agglutinative will, more than likely, come off.

If you accept your car to a radiator repair store to repair a leaking radiator, yous will often find that they will repair metal radiator tanks but NOT repair plastic radiator tanks. Instead, the radiator repair store volition probably attempt to sell you a replacement radiator. The replacement radiator toll can be very loftier compared to just repairing something and so pocket-size and easily repairable.

Radiator tank repairs are not difficult at all. Merely go along in heed a few things when yous are repairing a croaky plastic radiator tank. Commencement, the repair has to withstand high operating temperatures (200°F or 94°C and up).

Second, the repair has to incorporate hot, pressurized coolant, making it immediately obvious when your weld is less-than-perfect. Because of the harsh operating conditions, the radiator tanks are made from glass-reinforced nylon, a plastic that features a loftier-softening point. The high-softening-point nylon plastic is what helps the plastic radiator tank withstand the pressure level and temperatures involved.

Adhesives don't stand a take a chance in such an surroundings. There's no way an adhesive bail tin can agree on over the long run at such temperatures with loftier-pressure water behind it.

The only true way to patch a plastic radiator tank is with a true fusion weld. The Radiator Repair Kit enables yous to cook pure nylon make full material straight into the base of operations material, creating a seamless, strong repair that volition last for the long haul.

Creating a durable weld repair is not as like shooting fish in a barrel on the radiator as it is on other plastic parts because of the high melting point of the nylon and the harsh operating conditions. However, by post-obit the uncomplicated step-by-step procedure we have outlined hither, yous will be making quality repairs in no time.

Step-past-Step - How to Repair a Plastic Radiator Tank

Step one

If you lot are repairing the radiator while information technology is still in the car, bleed the antifreeze until the level of the antifreeze is beneath the crevice line. This manner, the antifreeze won't seep out of the crack and ruin the repair. Clean the croaky expanse with Super Prep Plastic Cleaner.

Step two

If you take a heat gun, yous can speed up the repair procedure by softening the plastic. Preheat the area to exist welded with a heat gun. Heat slowly until the expanse in and around the five-groove begins to turn glossy. On long cracks, preheat a ii-inch section at a time and consummate the weld in that area before moving on.

Footstep 3

Cook a Five groove forth the crack line with the edge of the welder tip.

Step iv

Melt the Nylon rod into the v-groove with the airless plastic welder. The rod should come out melted and a piffling bit brown, but non discolored as well badly. The fumes are not very pleasant, and then work in a well-ventilated expanse.

Step five

Later on depositing the nylon rod into the v-groove, remove the rod from the welder tip and use the welder'south to mix together the new plastic with the radiator plastic. Keep mixing until the plastic is all one colour. Yous need a good mix of the existing plastic and the new plastic to become maximum strength.

Step vi

Let fourth dimension for the plastic to cool and resolidify. Repairing radiators will save you a lot of coin compared to a replacement radiator.

Some other Radiator Repair Example

Here is another plastic cracked radiator repair. The same methods are used hither. Nosotros are showing information technology to reinforce how elementary it is to set a radiator.

Pace i

If you are trying to fix the leak in the radiator while it is even so in the car, drain the antifreeze until the level of the antifreeze is below the cleft line. This way, the antifreeze won't seep out of the crack and ruin the repair. Clean the cracked area with Super Prep Plastic Cleaner.

Pace ii

If you lot are trying to fix the leak in the radiator while it is withal in the car, drain the antifreeze until the level of the antifreeze is below the crack line. This style, the antifreeze won't seep out of the fissure and ruin the repair. Make clean the croaky area with Super Prep Plastic Cleaner.

Footstep 3

Cook a V groove along the cleft line with the edge of the welder tip.

Step 4

Cook the Nylon rod into the v-groove with the airless plastic welder. The rod should come up out melted and a niggling bit brown, merely not discolored also badly. The fumes are non very pleasant, so work in a well-ventilated expanse.

Step 5

After depositing some melted nylon into the 5-groove, remove the rod from the welder tip and use the welder'due south heat to cook the rod and base material together until the weld surface area is the same color equally the balance of the tank. Mix it well then that you go practiced inter-mixing of the rod and the existing plastic. This is how you know you've got a good fusion weld.

Step 6

Wait for the plastic to absurd and resolidify, and you are finished. Repairing radiators will save you a lot of money compared to what a new radiator costs.

Plastic Radiator Repair Procedures

Here is how confident we are with the Radiator Repair Kit.

Drill a Hole

Polyvance'south radiator repair kit allows you to fix a leaking plastic radiator tank. To testify how confident we are with our Radiator repair kit, we drilled a pigsty in a perfectly adept radiator.

Crevice the Plastic

Not only did we drill a hole in the radiator, just nosotros cracked the radiator tank with a chisel.

V-Groove along the crevice line

Earlier you lot showtime repairing, y'all will demand to drain the radiator until the coolant level is below the hole. Create a 5-groove along the crack line near two thirds of the style through the thickness of the plastic. You tin either cook in a V-groove, or y'all can utilise a rotary tool and grind a v-groove like we did here. Be sure to round of any sharp edges.

Soften plastic with a Heat Gun

Plastic radiator tanks are made of nylon which has a very high melting bespeak of about 425°F (218°C). While information technology is non required, the repair volition go faster if you pre-soften the plastic with a heat gun.

Melt in new fabric

Melt the Nylon rod into the Vee groove with the plastic welder. The rod should come up out melted and a piffling bit dark-brown, only not discolored too badly.

Mix the new plastic with the onetime plastic

While the melted rod is withal hot, utilize the tip of the welder to stir together the new plastic and the radiator plastic. Go on mixing until the plastic is all 1 color. You need a expert mix of the existing plastic and the new plastic to reach maximum strength.

Test Results

The auto was started and run for 45 minutes with no signs of leaking.
