Vinegar in the Model A cooling system.
I'm using 3 gallons of vigegar ( temporarly) in the cooling system to dissolve
the rust in the block of my model B engine. It's been there 4 days, and the radiator is starting to leak, at a rate of 1 gallon in 8 minutes, right in front of the fan. There is no physical damage to either side of the radiator. I have run the engine for a total of 20 minutes, once on Feb 9 and once on Feb 13, when the leak started. The vinegar marked 5% acid on the label. I thought brass is acid resistant. Can the vinegar cause this radiator to leak? Bigphil Anaheim, CA |

Re: Vinegar in the Model A cooling system.
It didn't happen with mine, and I ran it for a month.

Re: Vinegar in the Model A cooling system.
Vinegar will etch copper, but all I could figure is that you had a weak spot. I'm really guessing, but I don't suspect the vinegar would start a leak in good metal.

Re: Vinegar in the Model A cooling system.
Maybe you had a hole that was plugged by a chuck of rust.

Re: Vinegar in the Model A cooling system.
Yep, it sounds like the radiator was shot, but kept from leaking by deposits. I ran vinegar for 30 days in mine and removed a lot of rust flakes from the block. My original radiator is still fine.

Re: Vinegar in the Model A cooling system.
It sounds like your motor was running hot hence the vinegar ,so it maybe past its useful life .As a temporary fix You could try a very small amount of Bars leak a 1/4 of the container .about 1/4 cup .For around town driving

Re: Vinegar in the Model A cooling system.
I was wondering if Bars leaks wrere already in ther and the Vinagar flushed it clear and exposed the damaged area, just a thought.

Re: Vinegar in the Model A cooling system.
What does the vinegar do to head gaskets?

Re: Vinegar in the Model A cooling system.
I use a product from Gunk called Gunk Anti Rust and Water pump Lube. It has worked very well with no problems or leaks. It comes in a small plastic bottle and I buy it from Farm and Fleet. I drain all Model A radiators in the fall and fill with fresh water in the spring. The Gunk product is added with the water and there is no rust all summer. It is cheap and works very well,

Re: Vinegar in the Model A cooling system.
I let mine set for 30 days. Then I drained it and refilled with water and baking soda. Then drained and flushed it several times before refilling with water and Prestone anti rust/water pump lube. I drove it about 75 miles today and everything is ok.

Re: Vinegar in the Model A cooling system.
Gaskets have as much chance as your radiator tubes ,I prefer to have it in the Radiator only if its a concentrated mix .

Re: Vinegar in the Model A cooling system.
after 30-40 days of having vinegar in my rad, I flush it with the garden hose, let the engine run for a good 10 minutes and fill with antifreeze and new water. Never a problem.

Re: Vinegar in the Model A cooling system.
With the vinegar treatment you will find every pinhole you didn't know you had. The only car I have had a problem with using vinegar is in my shop now. The owner started the job himself and had bad results. He had so much buildup in the engine and radiator, the vinegar broke it loose but instead of him draining it shortly after running the engine he let it sit for several weeks. Now all the junk broken loose has lodged itself in his original honeycomb radiator(Not an A).
