Dex-Cool Options

JT6Speed · 08-30-2023, 02:00 PM

My bottom tank is getting a little low, and I was wondering what people generally use for Dex-Cool.

Do you buy the AC Delco concentrate and dilute it yourself, or get the premix 50/50? I also saw Prestone makes a pre-mix Dex-Cool as well.

I use NAPA orange concentrate and dilute to 50/50 with DI water.

Better question is why would it be low. It's a closed system and should not be using or leaking any. My 2016 never used a drop. You might pressure test the system.

It’s perfectly normal for the bottom tank to get low at times. I believe it states this somewhere in the manual. My 2016 would get low every once in awhile. The top tank always stayed full.

Prestone 50/50 is what I use too.

Just added 24 oz to my 18 yesterday. Bottom was empty and top was 3/4. After 5 years im impressed that's all it's used

Napa Dexcool orange, and it's super tasty!

Thanks for the options. I figured most would use something other than AC Delco. I'm not worried that the car is "losing coolant" when it's just getting below the line, but I obviously don't want to let it go either.

Anything marked Dexcool 50/50 is good.

I agree with you. I added some to my v6 between 25-30 k miles.Now at 55k miles the bottom tank has dropped a little below the book, not really enough to add.
