I noticed something peculiar the other day. It' been very hot lately =
around 90-93F. i was driving my 16V and I noticed that it was running =
cooler than usual around 80-83C water temp and oil temp at 95C steady!! =
I figured it will be a loose ground so I poped the hood . Grounds were =
fine , but coolant was leaking from the sensor on top of the plastic =
coolant reservoir. I fixed the seal temporary so the system holds =
pressure and gave it another ride. It ran at normal temps abit warmer =
than earlier.
Now, everybody knows propylene glycol (Sierra) has better thermal =
conductivity and higher boiling point than ethylene glycol. What if I =
run 100% Sierra in a pressurized system?
in theory it should run cooler. Mecca cooling systems claims so.
Any input?
