The 4m40 overheated today. Replaced the thermostat which was nakkid, but still lots of white frothy bubbles coming out of radiator with cap off.
Anyone had this. Cracked head or gasket maybe? Radiator looks good and clean.
Help needed please...

Any idea of time it takes to get head off? Are there any threads here with details?
