2020-02-27 - Aluminum Coolant Expansion Tank Points
I was told today by another competitor that they were being assessed 5 pts for the aluminum expansion tank used on an EcoTec swapped Miata. When Jay saw the same tank during my Skype inspection I was told as long as it was no larger than the one that came with the engine there was no advantage, therefore, no gain or points. the original Malibu tank is plastic so I found an aluminum one that I thought to be safer.
A recent review of aluminum expansion tanks determined that they should be charged 5 points.
