Using Sulfuric acid to flush??

[smuesse]

I am just curious if it would hurt to put a bit of this in the cooling system while doing the flush. I just bought a bottle to take care of some plumbing issues at home and though this stuff might get some of the crud and things out of the cooling system. I was even wondering if it might bring a oil cooler back to life. I'm not saying I'm gonna run out and do it, I'm just curious if it would damage anything if just a little bit was used.

I wouldn't do it. You don't know how it is going to react with the internals of your cooling system.

Yeah that's what I am thinking. I was just curious about dumping it straight into the oil cooler and let it sit for a couple minutes then give it a very good flush. My oil cooler is at the top of the spec range with the temp so i was just wondering if there is a chance of rescuing it.

That stuff is nasty and will eat any hoses, and probably react with the block.

There is a totaled 6.0 on ebay right now. I would try it on a junk truck first! I have a feeling it would break down too much stuff and cause more problems.

Yeah, scratch that. lol thanks for entertaining my idea.
