Mattson's Custom Aluminum Radiator - Cool It

After the tanks were welded to the radiator core, the filler neck and hose necks were carefully welded so as not to allow any leaks.

Jeff used his dab 'n' go welding technique, using a 4043 welding rod. He created incredible, consistent beads around the base of each of the hose necks, petcock valve, and filler neck.

After the new aluminum radiator tanks and fittings were welded, it was tested for leaks. The radiator hose necks were capped and the petcock valve and filler neck were plugged. Then, the radiator was submerged into the water tank. The tank was tested with 15 psi of compressed air.

After the radiator passed the leak test, it was then sent over to Mattson's polisher, Juan Avalos. After applying rouge on the polishing wheel, Juan began muscling the big aluminum radiator and powerful polisher.

Juan stood next to the highly polished Mattson's custom aluminum radiator that will definitely cool down the massive 540ci 8.8L Arias drag engine with a 1071 BDS blower, which produces some 1,500 hp.

After the UPS driver dropped off the well-packaged Mattson's radiator,

Dan Dowdy unpacked, then unwrapped his new shiny pride and joy.

To increase the airflow through the new radiator, Dan made up a mounting bracket to install a pair of Spal 16-inch (pusher) electric fans.

The addition of the custom-made Mattson's aluminum radiator and Spal dual electric 16-inch fans will make a major difference in the Terraplane's overheating issues.
