Hi Bern, Thank you for your reply...your replies to me were very helpful in the past
I greatly appreciate.
When cold: antifreeze is 2 inches below the radiator neck.
I already installed an overflow container same as in cars. When warming up the thermostat opens so I can feel warm upper radiator hose
and the temperature gauge indicates around 185 no bubbles no overflow.
Suddenly when blowing snow the temp gauge falls to 0 and antifreeze
begins to go slowly to the overflow jar in 15 to 20 minutes the jar is full
and there are bubbles and the upper radiator hose is cold.
It is the symptom of a stuck closed thermostat so last summer I intalled a new
thermostat and before installation I boiled it in water and checked with a candy thermometer
to be sure it opens a the right temperature a new radiator was also intalled.
Some days I can clean my driveways and farm yard with the snow blower the temperature gauge stays normal and no overflow. I'm realy lost on that one.
Thank you for reading
