Golpher high capacity aluminium radiator
To improve cooling I installed a Golpher full aluminium radiator with 2 row 40 mm core (stock = 26 mm). It uses an S-type radiator cap whereas the stocker uses an N-type. After installing it, I've noticed the fans don't kick in as often as with the stock radiator so even with the stock fan the coolant temp. seems to be more stabile.
