Sorry Evercool but we beg to differ.

From what I understand, this should not make the radiator an anode. Grounding the the radiator ensures that stray current will not
flow through the radiator since current follows the least resistive path (which is the grounding wire).

I was under the impression that grounding the radiator core would cause any charge present in the coolant to dissipate in the radiator, encouraging corrosion.

FWIW, I had to order the Honda Type 2 long-life coolant from the US a few years ago as it is the recommended coolant for my Civic (as stated in the manual and on the sticker under the hood). This is also the same coolant used when the car came out of the factory.

The only locally available Honda coolant is the Type 1 (non-long-life)... and I never use it, much less aftermarket coolants.

My car will be 5 y/o this January and I have not changed the factory coolant once. It's still the blue-colored liquid without any hint of corrosion. I only top it up with Honda Type 2 coolant once or twice a year.
