I got this from hond-tech:

Stuck thermostat,stuck open

*is allowing coolant to flow through theradiator*at ALL times. Therefore when stopped, you have no airflow thru theradiator. This allows car to reach normal operating temps. Once back moving the airflow will cool the coolant/radiator enough to OVERCOOL the car because the OPEN thermostat is not working.

Basically, a thermostat will regulate the amount of coolant aloowed to flow into the*radiator*to dissapate heat.

Confused? Most are.


Yeah,I only drive country roads no traffic lights..
