I was going to say try a little first too, but someone already alluded to this idea.
Maybe try using 1/4 of the recommended dosage first, then increase if needed.
Could save a lot of money i guess if it works.
Probably works on small leaks better than larger leaks.
If i thought of this when i had my old Hyundai when the engine seals started to go, i'd probably be driving that total piece of junk around still and still would not know that it was a piece of junk
This is coming from someone who once used rock salt as an antifreeze at a time when i could not really afford to buy a gallon of antifreeze and the coming cold night crept up on me. Salt lowers the freezing point of water, but also acts to quickly eat up steel, so eventually it ate up the top radiator hose nipple and had to be replaced. As summer came the system was flushed and replaced with pure water for the time being. All that said and done, i got through the winter but had to buy a new nipple later some time.
Do i recommend this now? Not really unless it is going to be for a VERY short time period like one day so you can get through the night and get a gallon of the good stuff the very next day, then completely flush and replace with the good mix. I also wonder if anyone else has tried this nutty but effective idea. The alternative is a cracked block.
