Tip & How-To about GMC Sierra 1500
Emergency weld for all metal radiators. Those mechanically inclined
This is a procedure for emergency repair only when you can’t get to a shop and you need to fix a leak in a radiator. First you will need three things one d size battery 12 feet of #12 copper wire or 2 strands 6 feet long. And a pair of needle nosed pliers and some mechanical solder flux core 60/10 resin. Find the fin in the radiator that is leaking with the needle nose pliers remove the cooling fns, these are thin the actual water cores are thinker, once you find the leak with the needle nose pliers remove 1 to 2 inches of the cooling fins from the radiator (Ones Not holding water) give them a twist and pull out the thin fins. Next drain the radiator below the leak snip the cooling fin right where the leak is and with the needle nose pliers bend back the cooling fin by a ¼ inch on both sides. Clean with sand paper or dry as best as you can. Take the D size battery and remove the center carbon core by removing the top, this is toxic so keep it off your hands. Next wrap a wire around the positive post and wrap the other end of the wire around the d battery core. Now ground the radiator with the other cable to the negative side and place it near the crimped side using the d battery core on the area that is bent and put solder onto the bent fin, do this on both sides. Be sure the solder is silver before removing the d core from fin; also hold the core with the needle nose pliers so that you don’t get burned. Let cool add coolant heat the motor up to see if it leaks if it don’t your good to go, be sure to refill the radiator back up with fluid, anything will do to get you home, except motor oil brake fluid or transmission fluid. Beer wine water and antifreeze are the best. This will get you home till you get it fixed; this is for those that have that luck when you need it most it breaks.
