I had a major overheat today. Car was running great. It has only 60k miles on it and it started to run hot and quickly ran up to red. I pulled over at a gas station and filled up anti-freeze. Waited for it cool down and drove it a mile and begin to heat up (not to red this time) and parked it. It ran shitty when it got hot. What are the chances the head is warped? Any ideas on where to buy a rebuilt head? Thanks. tQ.
