Default Temperature gauge issue
Hi my 72 vette temperature gauge has a mind of its own ?? I changed the stock radiator with a aluminum radiator and the hoses .My issue is that the temperature gauge goes hot to 230-240 degrees for 15-20mn and than drops back to 200 degrees ? Is that normal or is there something wrong ??
