I have a BDR with a 427. Its been running on the hot side compared to last year. Last year it was around 80 c. Now its between 90 - 100 c. how full do I need the puke tank to be , and what mix do I use?
Thanks lots, Kep
1) The expansion tank is "self regulating," in that it will spit out the coolant until it finds its correct level -- you can't really overfill it (you'll just end up cleaning it up off the garage floor). FWIW, my level is about a half inch above the bottom of the tank.

2) 80 degrees is a little cool, 90 to 100 is not unusual in the least. Chances are, there is absolutely nothing wrong with your engine.
