Coolant

[dndodd]

I am considering doing the 3rd Radiator install myself.

Is this coolant - Pentosin Coolant/Antifreeze the same as the OE Porsche coolant?

Any idea how much I will need?

As far as anybody has been able to determine, the Pentosin is the "generic" form of the Porsche coolant.

As far as a definitive answer to that question, it is a closely guarded secret by Porsche, which is why or how they are able to charge more than $50 for a gallon of the stuff. The more paranoia they can induce in Porsche owners, the greater their profit on that item.

One thing is for sure, though, Porsche does not manufacture antifreeze, and a company that only made antifreeze for Porsche and no one else would quickly go out of business.

The general consensus is that a good silicate-free, extended life, antifreeze is adequate, and that you should not mix the different types of formulas, i.e., Organic Acid Technology (contains silicates and phosphates), Inorganic Acid Technology (silicates-free and "lifetime" or extended life), and Hybrid Organic Acid Technology (contains some silicates).

Hi,

I would recommend Wet Water. It is

expensive.

I believe Water Wetter is merely an additive.

If you flushing your system or installing the additional radiator I would use the Porsche recommended coolant (ie. Pentosin) as the base fluid topped off w/ a bottle of Water Wetter.

You can simply add PEAK Lifetime coolant to the Porsche coolant. Pick it up at Napa and other places in the 50/50 mix for $9.99/gal.

PEAK Lifetime coolant is one of the silicate-free coolants that is in the family of Organic Acid Technology formulas, as is the Pentosin.
