what would happen if my thermostat was bad? stuck open the temp would rise to the point of temp light coming on ,fan coming on, overflow would start puking....
Actually you have it backwards.
IF a thermostat stuck open cause overheating due to water going through sop fast it has no time to cool down, then how would it get hot to begin with??
A thermostat works like this:
When cold, the thermostat is closed. This keeps water in the engine to get it hot. As the temp increases, the thermostat opens up, letting water thriough to the rad. Eventually the the thermostat will stay open all the time (ie operating temperature.)
SO , how is an open stat going to cause overheating?? If a thermostat is stuck closed, not allowing any water in rad, how would that make it run cold?
Listen, I've run engines of all sorts without thermostats and the nresult is an enfgien that WILL NOT come up to operating temperature.
Also, thermostats are designed to fail in an open position. Why? Becuase it allows water to flow from engine to rad with out overheating the engine.
