Hi guys. The stock plastic expansion tank has the Cold and Hot levels on it. I swapped to a Moroso aluminum tank. When I use my vacuum refiller and gage drops to zero, expansion tank is filled to the VERY top under cap. How much should I lower level in tank before start the car and run a heat cycle? As well, with car DEAD COLD, what should be the coolant level in the tank? (Kinda confusing since tank is flat until it angles near the top). Should the level cold be up to or below the hose on little nipple out the back? Thanks in advance for replies.
