| Hi Bob and All.  A pressurized automotive cooling system using “propylene 
glycol” full strength is approximately 370.8°F (188.2°C). 50/50 mix of propylene 
glycol and distilled water with 
Pressurized system boiling point: 
~250–265°F (121–129°C). Has a Freeze protection: Down to ~-29°F (-34°C). O'Reilly Auto Parts sells Sierra brand 
full strength propylene glycol for $28 gal. You need to adjust PH occasional 
with DOWFROST™ pH Booster or similar. 
Drain every 3 to 5 years. I recommend using a “water 
Wetter” that aids in cooling. Even a well-maintained propylene glycol (PG) coolant system with a stable pH of 8.0 to 8.5 will eventually need to be changed. The key reason? Glycol degradation over time, which leads to acid formation, even in closed-loop systems.
