How to Repair a Radiator Mount Bracket

Reparing a Radiator Mount Bracket

Repairing a radiator mount bracket is not an easy process. The radiator support bracket serves as a frame for the radiator and is welded to the main frame of the vehicle. Your radiator would not be properly stabilized and would overheat if the brackets weren't secure. You should only have to repair these brackets if you've been in an accident. If the radiator support brackets are damaged, you should definitely consider possible frame damage as well.

Preparing for Removal
If you need to remove the radiator mounting brackets, then some equipment needs to be removed prior to removing the brackets. Remove any seals, glass, panels, and other components in order to get to the radiator support.

Bracket Removal
While you were removing all the extra parts that blocked your path to the radiator support, you may have noticed the spot welds that secure the frame of the car to the radiator support. Spot welds look like circular dents in the metal. These need to be removed in order to remove the radiator brackets. Special drill bits are made to remove spot welds. Drilling out the spot welds is the easiest way to remove the welds from the metal. Use the holes made from drilling to serve as a guide when you replace the old brackets with new brackets. Vehicles vary in the number of spot welds, however, every six inches is about average. Once all of the spot welds are removed, lift the brackets out and replace them.

Bracket Repair
Repairing the radiator brackets is pretty straightforward. Once the brackets are off, you can replace them, or try to straighten the brackets with a hammer. If the radiator brackets do not straighten out, buy a new radiator support, as once metal is bent it's not as structurally sound. If you decide to repair the brackets, make sure to take the brackets to be repainted or paint them yourself.

Bracket Reinstallation
The new support must be welded back in. The radiator support ensures that all four major frame rails align properly and provide strength to the front end suspension. Make sure after spot welding the brackets back on that all the bolts that were removed are bolted back to the correct place such as the headlights, fenders, seals and whatever else had to be taken apart to reach the radiator support.

Helpful Tips
A good drill and drill bits are vital for this procedure. Use a slightly bigger bit than the spot weld to ensure that all the welds are properly removed.

You will also need a ratchet, sockets, and screwdrivers to remove any of the parts that are in the way of removing and installing radiator brackets.

Invest in special primers for the brackets to prevent rust from forming around the welded areas. Once the brackets are rusted, the support is not structurally sound.

Repairing the radiator support is daunting because of the important job the support has. If structural parts fail, you could be in real danger if you get into an accident. Be vigilant to ensure proper installation of all the parts.
