[DeTomaso] Time for coolant flush

A quality antifreeze should contain corrosion inhibitors, but there are specific stand-alone corrosion inhibitors available like No-Rosion that you can add, or alternatively you can add a sacrificial anode, usually a zinc plug.
An ideal coolant pH is between 7 & 8, and antifreeze is more alkali than water so adding more will increase pH. Pure water has a higher specific heat capacity (better cooling), so ideally use enough antifreeze for your climatic conditions to prevent freezing and maintain the pH toward the neutral (7) side to help prevent galvanic corrosion.

Jim,
What is making you think you need to dump perfectly good coolant in a perfectly bled system? Getting all the air out of the cooling system is a PIA and changing coolant on a car driven so little borders on ‘recreational maintenance’.
Don’t tease the animals….
