Can a broken hose connection on a plastic radiator be repaired?

Hose connections on plastic radiators can crack and break, causing coolant to leak, which can expose the engine to potential overheating unless repaired swiftly. Fortunately, another upside to plastic radiators is that they are relatively easier to fix than traditional brass radiators.

What should I use to repair a cracked radiator?

If you are repairing the radiator while it is still in the car, drain the antifreeze until the level of the antifreeze is below the crack 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.

Can a plastic radiator be repaired with a metal tank?

It may fix the radiator leak temporarily, but over time, the radiator adhesive will, more than likely, come off. If you take your car to a radiator repair shop to repair a leaking radiator, you will often find that they will repair metal radiator tanks but NOT repair plastic radiator tanks.

What should I do if I have a hole in my radiator?

Before you start repairing, you will need to drain the radiator until the coolant level is below the hole. Create a V-groove along the crack line about two thirds of the way through the thickness of the plastic. You can either melt in a V-groove, or you can use a rotary tool and grind a v-groove like we did here.

How do you repair a broken plastic radiator?

Heat the welding rod with the welder. Once the rod has begun to melt, place it on one side of the hose connector. Press the two broken surfaces together and hold for several minutes while the welding rod cools. Allow the plastic welding to set before reinstalling the radiator.

What should I do if my radiator hose connector is broken?

Clean the entire surface of the radiator with a water hose, checking for other leaks while the radiator is out of the vehicle. Remove any debris from the area of the broken hose connector. Sand the entire area, paying particular attention to the broken surfaces. Heat the two broken surfaces of the hose connector with the air-free plastic welder.

Can a crack in a plastic radiator cause a leak?

There are various parts of the plastic radiator that can leak: you may spot a crack on the hose or the body of the radiator itself. Before you get to the actual repair, you may want to examine the fittings that lead to the radiator. In case the leak is coming from the radiator, put your old clothes on, roll up sleeves, and follow the steps below.

What’s the best way to seal a radiator hose?

I’ve always used Permatex Aviation “Form-A-Gasket” to seal radiator and heater hose ends to their connector. Lightly and evenly coat the dry and cleaned connector, plus about an inch of inside the hose end. Let it setup for a couple of hours to allow most of the solvent to blow off, then slide the hose on and clamp.
