I performed a little radiator modification for a fellow RME member yesterday.
The radiator outlet spigot needed to be relocated from one side of the upper tank to the other.
Here is how the radiator arrived to me and where the outlet needs to moved to.
I stuffed a rag into the outlet before beginning to cut to prevent debris from entering the radiator tank. I used a hack saw to minimize debris.
I use a grinder’s grease made by Formax out of Grand Rapids, MI. I coat my Roloc disks to prolong them from loading up with aluminum.
I lightly dressed the area where I removed the spigot to prepare for welding a cap on it.
I cut a cover for the old opening from some .125” 5052 aluminum.
I then inverted the radiator to keep the tank on the bottom and used a hole saw to cut the new opening where I was instructed to do so.
Prior to prepping for the welding process I vacuumed the tank out and rinsed with water keeping the tank low so no debris would migrate into the core.
Outlet located into position and lightly clamped for tack welding.
Outlet completely welded using 5356 TIG rod.
Cover weld completed.
Radiator completed and ready to be returned to its owner.
I also threw together a short YouTube video if interested.
Thanks for looking.
