Vette(s): Original owner 89 C4 Coupe,Silver with Red Int, late model C6 wheels
Not all the cars have a chip for the cooling. I changed our radiator to a after market aluminum one, added a 180 thermostat and had to add a second temp sender in the front of the left hand cylinder head which triggers the cooling fan to come on at 180-185 degrees. All works very well but on hot days (SoCal) with the A/C on in slow traffic it will still go to 200 or 210. Some cars had HD cooling and the second temp sender is already in the head. I believe that may be when a chip mod is needed. Trying to remove the giant allen head plug in the head was futile. we had to drill it out and tap the opening to accept the 2nd sender.
