Felix;
To diagnose a similar problem I had mechanic "sniff" the air in the
expansion tank with the exhaust analyzer. This eliminated the cracked
head possibility because there were no hydrocarbons present. The culprit
was a clogged radiator. Removed it from the vehicle and had it "blasted"
out.
Drive Safely & Good Luck
