I have a pretty much stock 93 mustang advanced 14* degrees with under drive pullies. I notice that when running the ac or just at idle it runs around the m to the a on a stock gauge. I do have a 180 degree thermostat with a autozone replacement radiator. Should I go with a bigger radiator or will a electric fan help keep the temp down? Is it running hot or is that normal?

 

Well since the gauge is reading in the " NORMAL " area then it is normal...

 

have you put a real gauge on it instead of going by what the stock gauge says?

 

Sorry should of been a little more detailed. I am going to replace the stock gauge with aftermarket, waiting for parts to be mailed. Be fore replacing radiator it always ran around the n or o of normal at idle and ran higher if the ac was on. I probably should of just bought the bigger radiator for piece of mind.
