I am going to replace my bad coolant level sensor, I was thinking of going to one thous U-Pull junkyards and pull a coolant level sensor off a random 97-04 grand prix, but I am not guaranteed that it is going to work and I got to replace the coolant every time I switch the sensor. However the senor would probably only cost me like $5, maybe I should grab two of them, or should I play it safe and order it new for $50 which is allot of money to me.
