OK. So I'm running Prestone Super Flush in my 94 vette. (2 days, then flushing out). I've heard not to use this stuff but its too late. Has anyone run a flushing agent in the cooling system and if so, had any problems. I've run it in other cars in the past and have never had issues. Its just that today I was reading the Chilton Handbook to find out how to flush and it warned not to use these products in these egines. GREAT! I hope I hear that some of you have used this stuff with no problems.

From one Rick to Another....I hope that you hear good news. I also considered using some of the Prestone Super Flush recently as I need to do a Flush and Fill also. Now I know better and will not.
I would guess that you probably are OK and have not damaged anything....just get that stuff out of there and fill r' up.
Used it in my 89 a few years back and used the Prestone flush kit. No problems yet...................
Don't know about leaving it in there for 2 days though; I only had mine in for about the 30 min. it took me to drive to work where I did the dump and flush routine.
I was told by my Corvette mechanic, not to use any of that stuff. Just flush it a few times with distilled water, then add your antifreeze and maybe some Water-Wetter. I don't know why, I've done it with all of older cars - maybe it has something to do with aluminum heads.
Meh. I think these mechanics are FOS. The only thing a flush could do is uncover a leak that was about to happen anyway. Not the product's fault. JMO.
You may be right. But I have a new radiator, hoses, water pump. Is there anything corrosive in the flush product? Like I said, I've used it in other vehicles I've owned with no problem, I just wondered is there is something different about an LT1 that may cause a problem.
