On sunday I decided to flush my radiator... well, everything went normal until monday night when it overheated... it seems some air bubbles are stuck in the engine and it made my engine overheat It reached the top of the temperature gauge for a few mins until it suddenly dropped... Everything seems normal right now... engine is strong... what else can be harmed when overheating?

 

main bearings and rod bearing...i did the3 same thing...now the motor is in about 300 pieces...complete bottom end rebuild...chck for knock sounds a bit like lifter tappet...

No knocking sounds... oil is normal

 

if it suddenly dropped i can guarentee that you fried your sending unit...or you happen to get lucky and that was a air bubble that worked its way out at the right time

 

If everything is running fine, I wouldnt worry about it. One question though, why did you run it hot like that for a few minutes? Again, if its running fine, you might have dodged a bullet but next time as soon as you see it getting hot like that, kill it!

 

well, it dropped but it didnt die... it just lowered and I kept getting a reading... today I took the car out and everything is fine... I hope I didn't break anything

BTW, the car has 64,000 miles

 

Well, I was confused and kept thinking "must be an air bubble..." but after a few mins it was getting even hotter, so I killed it.. it did reach the 260 mark when on and the CHECK GAUGES light came on... the temp changed so quickly It took me a few mins to react

 

I have done several radiators that always happens. If it jumps up and down the engine isnt that hot the air bubble is. Your engine temp probably didnt rise at all.

 

That's what I was thinking... it just dropped to a normal temp too fast...
