coolant system bleeding air
hello, My 99 Z34 3800 has had coolant elbow problems. Now that's fixed I'm pretty sure. Now the issue is bleeding the air from the system. Ive tried everything, still not fixed. Is this a specific procedure that I'm not aware of? I'm pulling my hair out over this. Ive had to replace the rad and temp sender twice. Temp gauge only reads 140 degrees at any time. Ive raised the frontend, everything else suggested to no success. What am I doing wrong? This car has been a great car, over 200k, still has the original trans. This problem is/has driven me crazy. Please help! Muley

Google "Burping cooling system" this may help you.
I had issues with my 2004 Impala (3.4L) burped it multiple times turned out to be a blown head gasket.
Remember a blown head gasket does not always show up with obvious signs like milkshake oil, coolant level dropping fast, exhaust steam/smell etc.
I have had two different vehicles blow head gaskets and tell tale signs were very subtle. Both times I caught it right away, only had to work on the top end saving me $$$.
