Cooling flush with CLR
Is it possible to use this for flushing out the deposits in the cooling system. Has anyone tried this. I thought about using this. I just want to get some feed back on this topic before i try it out.

Just trying to save a few buck. I have CLR here at home already. So I had the idea of using it. I was just curious. Thank you.

CLR will eat all the soft metals in your cooling system.

What's the best way to get all the coolant passages in an older block and heads cleaned out?

Use a radiator flush product that doesn't use a strong acid.
