I'm not 100% sure, but there may be 2 temp sensors, 1 for emc and one for the guage. Maybe the radiator is clogged even though you gave it a flush. Is your temp guage going to full hot? My 94 will somtimes climb 2/3 of the way thru normal befor fan kicks in to cool it down. Another thing to consider is the waterpump. If your going to tackle that, be sure to change the timing belt while your in there and everything is apart. |
