My van started to overheat after idling for awhile. I changed the thermostat and that did not help the fans are working, but I have to run the heater on high to help cool the engine. It normally runs right below half on the gauge when the gauge hits the half mark the fans would come on and cool it back down. I finally had to unplug the coolant sensor and let the fans run all the time to keep it normal. I then changed the coolant sensor and plugged it back up. It idled at normal temperature then went to half mark and the fans turned on. I thought that fixed it but when I started driving on the highway it started to climb in temperature again. I pulled over and checked the fans they were both working. Does the fans have two speeds. After I changed the sensor and the fans came on for awhile they speed up turning a lot faster. I thought great it must be fixed. Why am I having to unplug the sensor and make the fans run all the time to cool the engine? I am at my wits end.
have the same problem?
