ok, heres the deal, i have a 91 LX notch, with an 89 GT motor (and EVERYTHING else, icluding radiator, overflow, and wiring) and well my car never came with a coolant overflow cap. i do have a cap off a, 89 LX, but i think there is wiring for use with the one with the sensor. if i dont use the sensor, will i creat problems? i can find the cap i need anywhere (its like 50 bucks from 5 0 resto and i dotn ave that money).
