OK heres my problem, i got a 89 rs camaro that normaly runs at 210 degrees. i started running around 220 to 240 the last 2 weeks. i just rebuilt my TBI and redid the timing but i see the the temp has not droped. i just replaced the thermo and the radiator about 4 months ago, also the fan is always on. can anyone throw me some advice. oh-ya i live in cali and its been hot here in the 90's and 100's the last 2 weeks or so, could this be a factor

 

Did you get a 160 thermostat? Is your front skirt ok or is it missing? I got my 1 fan wired to always be on too. Do you have 50/50 water/anitfreeze? Are you running lean? Do you have afternarket accessory pullies?

I'm sending this to the General Tech board and the Cooling board too.
