Re: Foam in Anti-freeze
Drained the anti-freeze (cold engine). All that foam is just the result of the anti-freeze dropping from the spigot to the pan. If this occurs via simple, mild agitation, I would think that it rules out head gasket and air seeping in from the water pump.
Flushed and refilled with plain water. I'm gonna run with water for a while, flush again, fill with water, rinse repeat. Definitely not gonna reuse the anti-freeze. Leo |

Re: Foam in Anti-freeze
You could use your espresso maker to test the new brand antifreeze. Just foam it like you would froth some milk. Or maybe just use the electric egg beater. Do this when you wife is out of the house for a while.

As far as fresh anti-freeze, I'm sure I read where that Zerex low-silicate (that I used prior) was the way to go for old cars. |

Re: Foam in Anti-freeze
Update. Still running with water.
I put some of the drained anti-freeze (AF) in a water bottle, shook it up, and the result was crazy foam. Does that indicate oil/grease in the AF? Did the same think with unused AF and it was fine. I'm gonna give the water some more time but do you think I should add some laundry detergent to rid the system of any grease, prior to refilling with AF? |

Re: Foam in Anti-freeze
Dawn, to be specific. It cuts oil and grease really well. Especially at 140°.

I used to use Sierra. It takes a different type of tester to check it's protection level. |
