Philip,
Deficiencies in the cooling system will be exploited when standing still -
lots less cooling air flow. I've also had hoses that collapse on the inlet
side only at speed when there is higher coolant flow and greater suction
pressure. Use the antifreeze for its anti-corrosive properties. The rust
and corrosion will hurt you fast. Aside from the Ethylene and Diethylene
Glycol in the anti-freeze, extra corrosion inhibitors are added as well.
