What Coolant To Use

Recommended Posts

  • Moderators

What tires, what oil and such, are always debated. But the hot topic is always coolant. :rolleyes:

You might want to read this first. I contacted Chevorn/Texaco years ago.


Porsche has gone pink.

What I noticed over the past year when you could for the first time buy a 1 gallon jug, instead of the 1 quart jug, is that the containers said made in the US and had PCNA on it. To me that means the coolant is produced in the US, rather than importing coolant from Europe.

So, I compare the yellow/green to the pink. For you chemist out there, they had the same chemicals listed on the lables.

Ethylen glyco 107-21-1. Diethylen glycol 111-46-6. Sebacic acid 111-20-6. Sodium hydroxide 1310-73-2. Water 7732-18-5. Plus a dye.

According to the mechanic Porsche started using pink for the Cayenne when it first came out. When the 987 came out for model year 2005 it was also pink. The yellow has been superseded by the pink. They can be mixed. They do have different part numbers. Porsche wants the same pink stuff to be used for all cars.
