Pink Coolant in a 2017 Suburban


Recommended Posts

Bought a used 2017 Suburban awhile back. Noticed the coolant was a little low, so I bought some Dexcool compatible as recommended by my LAP store. Before I added it, I pulled a sample and what’s in there is as pink as pink can be. The Preston Dexcool is orange. Did I buy the wrong coolant, or did the previous owner/dealer put in the wrong stuff? Do I just need to flush and fill with orange?

Yes bought new. I haven’t seen the prestige dexcool color so I really can’t compare.

It looks the same to me, not quite orange in color but close. Btw, like your CAI, nice job [emoji1303]

So I guess I need to break the seal on a jug of Dexcool and compare the two. Is there a pink coolant? Going by the label color, maybe Mercedes coolant? I don’t want to mix types and I don’t want to use the wrong type... everything says use Dexcool, so I guess I’m flushing if it’s not a match.

So this is what I have found as far as color. The coolant is not the color of the cap. This appears to be what is in my truck.

Looks like what we have as well.  I also assume the color would get lighter when it is mixed 50/50.  Or, is it already mixed?


Good question. Found that on the internet. I would only use the mix. It’s way easier

Thank you! Why the cap and colors on the jug wouldn’t match the contents boggles the mind. Am I the only one who thinks of antifreeze in terms of color?

I don't know why.  I would have never through that the antifreeze cap color would match.  Not even spray paint can lids match, just gives you a general direction of where the color lies on the spectrum.  It's just a rough estimate and everyone refers to Dexcool as being orange so I guess it makes sense.  Was Dexcool ever more orange than it is today?  Is it still as sludgy as it used to be?
