New one on me! (Checking Coolant with a Meter)

[POS Racing]

Any of you slack jawed yokels ever seen this method for testing your coolant??

[POS Racing]

Another vid!



I do have an Anti-Freeze Hydrometer.....

[JDSM]

wow, something to think about...

[cone-cerned]

First I've heard of this test. But, until I started autocrossing, I had never heard of anyone changing their brake fluid. The test is easy enough to do so I will give it a shot this afternoon.

LOL!

When I was working in shops we tested coolant pH with test strips. Similar to this;

The other reason besides deteriorating gaskets is the risk of galvanic corrosion. It occurs faster in the presence of highly acidic or basic solutions. What the videos actually show is the current generated by a galvanic battery. A small current is generated between the dissimilar metals when in the presence of an electrolyte, in this case the antifreeze.

Very interesting and insightful....

I tried it and got nothing, 0 volts...

did anybody notice that both the vids mention the red fluid?

[POS Racing]

I got 0.14V on the kids 2002 and 0.06V on my 1994

So the kids car needs attention and mine is borderline??

[Avarice]

Well, I just flushed out all the fluid and replaced it with piss. Learned that from Red Dawn!

Are you using red fluid? jdcanadian has a point.

Did the vatos at the zone tell you about this? Did you use the HF VOM?

Did you flush and leave the old stuff for your neighbors' cats?

How long did you leave the leads in the red fluid? Did you dry it with a fat quarter.

(see what I did there?)

Let me see if I can answer this in order.

• No
• I feel coolant shouldn't be judged strictly on its color.
• Nope Garage Journal
• Yes
• Not yet. (Here Kitty, Kitty, Kitty)
• Until the number stayed the same on the VOM
• No fat quarters were harmed in the testing.
• Yes, Yes I did.....
