overheating issue
Recently my low coolant light came on, and having checked the level in the overflow, I found the coolant was right where it's supposed to be. So I just pretty much ignore the light. Well today I was out cruising a bit and came across a new bodystyle BMW M3, so we decide to go from a roll on the interstate. Well we're basically even (his car had 4 people, my car only had me). It was a good race. We shut down at about 120-130 and I look down at my temp gauge. It was almost in the red. So only in that short time of WoT, my engine temp went up quickly. I went back down to cruising speed, turned on the AC, and the temp pretty much went back to normal, but still a bit high.
What would cause something like this? If I just cruise around I don't have any cooling issues. But one good run through the gears and it's hot as hell.
