2006 Mustang Roush 2 bought new 8 months ago (Still under warranty it's just Monday is a ways away to get it to the dealer) is overheating and the Antifreeze is boiling over the reservoir. It just started Friday night after the Ford dealer closed lol. So I tried to drain the Radiator and refill with 50\50 and after about 15 minutes of running the reservoir is boiling over although the temp gauge reads normal except when it staled Friday night going about 120mph. My gauge reader has it hitting 219 temp in 15 minutes.
Any ideas????

 

Don't drive 120.
Check to make sure WP is good, and thermostat is open/clean/free flowing @ temp.

 

Thanks for the info going downsairs to check those things now.

Car seems to cruise at 120 lol; it was just a quick burst to get around some trucks on the 2 south going up an incline. I trust Ford made the car with the idea someone may what to hit 120 once and awhile. I what even get into the gas tank that only takes 10 gallons or the shaker system, the seat hooks on the back breaking off after one use so on and on.

This is my second 06 Stang so I do like Mustangs and I have an Explore and a 72 Torino so I don’t hate Ford it just sounds like it.
