I was going to work this morning, all was fine, picked up my friend, we go on the boulevard and then Bam, the ding-dings went off, temp is redline...

Pulled over, stopped the car, waited 5 minutes, restart and redline again... I opened the hood, no leaks and the hoses were cold and the rad is full of coolant...

I had a custom muffler installed yerterday, I doubt it has anything to do with it, just thought I`d mention it...car was doing fine yesterday...

So I`m thinking thermostat, anybody has any other ideas....

Had the car towed home...I`m at work so I`ll check up on it this afternoon...

Any insight appreciated
