## Questions & Answers

**Q: Well if this is orange what is the pink and where do you find pink.**
A: This is orange because it is 100% pure DEXCOOL from the Jug. When you dilute this with distilled water to 50/50 it becomes pink/red, which is what I put in the car. Check your cars owners manual to be completely sure what coolant and how much dilution you need.

**Q: How much will my Silverado hold?**
A: CHECK THE HANDBOOK FOR CAPACITIES. SHOULD BE 50% WATEER

**Q: Will this coolant work for a 1978 gmc c15 truck?**
A: This does NOT go in a 1978 GMC C15 truck. You would need green ethylene glycol.

**Q: Will this work on a 1997 chevy camaro z28?**
A: If your coolant is orange then yes you need Dex Cool. Haven’t seen a 97 Camaro in a long time some I had my 91 Mustang GT Turbocharged and all the other good stuff playing with all GM Sports Cars. Have to say GM Sports Cars kinda look good in the rear view mirror. Problem is they fade away so fast every time I looked at it. 

That is long gone now. Viper time.
