Coolant levels.....

[Planman350i]

Hello, my 350 has been running a bit warm lately - lots of use of override fan. When it was fully cool I checked the expansion tank and noticied the level was a fair bit higher than when I last checked it. Is this a sign of blockage somewhere...bust thermostat???

Any help appreciated.

What is the level in the swan neck? Make sure that it is full and don't worry about "high levels in the expansion tank."
