My take on this is that the colder the water the more heat that it will need to absorb.

The downside of colder water is that it is 'harder' or denser. So I'm convinced that it led to blowing a head-gasket. Probably because there was too much water going in one particular cylinder. Sometimes what goes on in an engine is mysterious.

I guess so.

Hope so.

Picture: (Garrett was installed this week)

2003 Renault Scenic - 30% more power with no loss in fuel economy.
1991 Toyota GT4 - more economical before ST215W engine-swap.
previous: Water-Injected Mitsubishi ~33% improved.
future - probably a Prius
