Removing OEM heat exchanger, fluid drained was green.Blue is for the heat exchanger and green is for the radiators.. it should be obvious which one goes where when you pull off the fill caps.
How does it use two?It uses both man. So you can determine what is leaking by color
Green for engine coolant
Blue for intercooler/heat exchanger
It's probably the exact same fluid just different color for determining leaks is my guess
Bro its green, this is from my Toyota dealer and what I usedI have found two totally different part numbers that bmw use for their coolant . One is a green fluid (ht12) with part number 83192468442 and the other one is blue with part number 82142209769 .
so which one should be used for the Supra ?
Yes, no IAT drop comparing log to log, however; Car cools down much faster and is due to that less likely to heat soakBased on what I read this seems to not be worth it then correct? Unless someone else can show me some logs of IATs dropping significantly wile Dig racing. For rolls i think it may help a little if you cruise around for a bit between pulls (which is normally the case).
