Hello everyone i'm new here and glad i found you. I've had my 90 tr for about a year and love it. recently i noticed my car was reaching higher temps than normal on a sunday drive so i drove home and parked it. i called a ferrari mechanic the next day and he had me troubleshoot the problem and said it was a bad thermo sensor. said it is the under radiator. anyone out there ever fix thier own or should i take it to dealer. any feedback would be great. the car has been sitting for a few weeks and its killing me since we've been having such great weather in san diego. just have'nt had the time to set appointment and fix it.
