Hey all. Maybe I can get some help with an issue I am not familiar with. I have a 1996 Taurus LX. Its the Duratec V6. I recently did a coolant flush and fill on it. After running it to make sure all is well and to bleed it out, it seemed fine. I then replaced the tank cap and while running it in idle with the ac
on, the needle went up just under hot. I shut off the air and the fans stayed on high speed until it went back to normal. I plugged in my OTC scanner and the temp showed that with the fans on high and ac
off, it sat at 190*. After letting the car sit for about an hour, I started it again this time with the cover on the tank. The car idled for about 15 mins at 190* and then it went up to 223* and then the high speed relay kicked on the fans. I checked for cold spots on hoses, radiator, heater hoses and thermostat housing. All was well. After using the OTC scan tool to rule out a possible gauge malfunction, it was fine. Does anyone know if there is a Low/High speed fan relay in the box at all. Cannot find one in the car. The high speed fan kicks on but the low speed is looking like the issue. Both my 2000 Duratecs have not given me this problem. Also, is there a coolant temp sensor on this model year? Have not seen one under the hood like my 2000 models. Any help would be great. Thanks
You have a two speed system. Sounds like the low speed is not functional
for some reason. Earlier Taurus had the low speed controlled be a relay
and a dropping resistor in the wheel well. Some of the newer ones
had a actual 2 speed 2 winding fan as i recall. ON a 1996, the fans are
controlled be the CCRM/IRCM which is on the drivers side next to the
battery. around 98, they switched to discrete relays.
So, you could have a bad dropping resistor, bad relay in CCRM
some wiring issue potentially.
