1500 Radiator Drain Plug thread size

[chief]

Correct the drain plug is a flanged bolt 10x10.

Did I misunderstand again?  I believe the 6x12 is the bleed on the water pump, 10x10 is the one on the radiator

Should be 10 mm

Does anybody out there know what the thread size for the drain plug on a 1500 radiator. My son drained the radiator and stripped the threads and I need to to re-tap.  Anybody know what the size is?  12mm?   thx......Ed
