Hit redline driving to school today. Stopped, let it cool then put some water in it(Didn't need much) to top it off. Went to drive it home and as soon as it was about to hit redline again, I guess the t-stat or something finally broke loose cause then the temp dropped almost back to normal.
I've dealt with this same problem before in this car. I replaced the t-stat and flushed. Worked fine for a little over a month. I only ran flush through it once though opposed to several times as suggested, since i saw it dropped a lot of crud and started running smoothly again.
Maybe there is clogging? Should I try just flushing the thing a couple times?
