Coolant Test

[Rawze]

ELC red coolant is usually good for about 400k miles if it does not get contaminated.

also, if you only gave roughly $20/gallon for the new coolant then you got a decent price on it... and that is not considered expensive at all for the typical ELC-red.

I run ELC red in all my vehicles, cars, trucks, everything... never had an issue with it.

and.. the old coolant might not have been 50/50 any more and likely has gotten more concentrated due to evaporation over the years... so yeah, the color will be different.

next, is that the coolant is old. The ph might not be all that off, but who knows what other contaminants, wear metals, etc. are built up in it by now. It is still best to change it.


You also need to check the expiration dates on those test strips. They do go bad and get stale. - i can't tell you how many times that I went somewhere to purchase test strips, and they handed me expired ones. They then looked at me sideways when I pointed it out to them, handing them back, and demanding test strips that were not out-dated. Most people never pay attention to this.

Lastly, the new coolant checking out at 1.1 is quite normal and actually is a good thing for the most part. As it ages, it typically moves up and to the right, further into the green zone .. and not the other direction.

just my thoughts.
