Is running straight vinegar in the cooling system SAFE for Skip's water pumps (seals) and for aluminum heads?
The threads here that have discussed this at length mention 5%. We're talking about ordinary 5% white vinegar that you buy in supermarkets.are you proposing this just to clean the system? vinegar has different levels of acidity so we need to know the level of acidity you are suggesting.
I dunno... maybe. White vinegar is about $5 a gallon.i think rariator flush is cheaper
You should search this forum using the word "vinegar" and read all the various posts. I found it very interesting. Fifty million flat head guys can't all be wrong.i am not sure of how much scale will then be floating around in your cooling system to clog the radiator or heater core.
Wow Cecil! Looks like you did some good with your vinegar treatment!Here's what the vinegar looked like after a couple of weeks in my block. This was after it was drained for a couple of days.
I have a new core on my radiator and didn't chance running vinegar through it. Instead during the winter I took the hoses off and let pure vinegar set in my engine for a week or so. The vinegar quickly turned to a rust color but I didn't see chunks of anything when I flushed it. However it did discolor the concrete driveway a permanent rust color where I flushed it. So be aware of this when you flush.
Some members have discussed using dishwasher detergent to clean the engine. I wonder about CLR. It is advertised to clean calcium and scaling. I am not satisfied yet my engine block is clean.
