    Filling cooling system?

    Just finished my cam swap, and I'm ready to put coolant back in this thing, just wondering exactly how though? My guess is since it's a pressurized system, to just pour in through the overflow bottle, but I'm probably wrong haha. I'm crossing my fingers on the first startup, everything lined up right, but theres always that second guessing. Any help is appreciated with this, Thanks!

    Takes almost 4 gallons to refill one of these after the pump has been off. I use an airlift that puts a vacuum on the system and sucks the coolant in to prevent air bubbles. Without it, you can fill the overflow almost to the top, reinstall the cap, and put it through a heat cycle. Make sure you let it run long enough for the tstat to open.
