The rad is set back abot 3 inches away from the cooler, would it be worth bringing it forward towards the GRS more?
The fans have an arrow pointing towards the rad saying "AIR FLOW" I did origionally wire them up wrong and they were pushing air out but now I've swapped the wires around and they are pushing air through the cooler towards the rad. I'll check for an air leek, but its just had a new water pump and coolant.
