Doing a coolant flush and change on my V-Twin RS. The drain plug on the radiator seemed overly tight when I loosened it to drain the coolant. Reinstalled finger tight and then 1/4 turn with a ratchet. Filled with coolant and had a small leak. Torqued plug to spec with torque wrench. Still had small leak. Decided to remove plug and change the rubber o-ring. When loosening the plug the small leak instantly became a large leak. The area where the drain plug threads mounts into the body of the radiator cracked.

As far as I know they coolant hasn't ever been changed and the drain plug was factory applied.

Ordered a new radiator and prayed it was not on back order. Good news is its not

Makes me wonder if this is a common issue with the Spyder? Anybody here of this before?

I'm not an ace mechanic, I'm a pretty good parts changer and I've done maintenance type work on many an automotive type vehicle and have never seen an issue like this.
