Totally agree!

 

I did not say miles, I said doubt. These newer coolants are rated for way more miles then most people ever run them for.

Doubt is different. Different as in ---> the coolant looks funny or it was mixed with some other un-known chemical or coolant to get you home or to a garage. I know it is not a worry for myself as the engine is never in my car long enough to take a coolant to expiration mileage or years.

Shoot I even put Gatorade in a snowmobile once to get me off the mountain.

 

Sorry you disagree or should In say I misunderstood your statement but I have bought and sold well over 100 cars and I've seen a lot of coolant that way past its life span and the cooling systems were in bad shape.

 

Yeah more often that is the case with your high mileage or years basic transportation spam cans. Most Porsches are not in that same classification.

But like I said, change more frequently. I have no issues letting coolant go in any thing I drive 3 or maybe even 4 years. But I will not go 5 or more and 150k miles like many of these coolant makers state there products are good for.

 

The main thing for coolant in a German car is that the coolant does not have nitrates or silicates. This will avoid build up and deposits in the cooling system.

I think Zerex makes a coolant that is compatible and not that expensive. However, purchasing the Porsche/VW coolant is a small price to pay for the 996tt.

 

i think(?) that is why it is imperative not to mix older configurations of this magic stuff. if OAT mixes with OAT, you're AOK. i also believe that once you've decided what type of coolant to use, ( and as others have wisely suggested change it every cpl/few years? ) and top off with a proper 50/50 mix, we would have nothing left to do but talk about coolant, as no issues would arise. pink + pink and distilled water = good. the vw/audi stuff is pink, perfectly fine to use, and a poorly kept secret among porschephiles i like it so much,.. i suggested it... again

 

Any of you guys use water wetter from redline? I have used it for years in other cars and bikes and was thinking of dumping a bottle in the turbo! Thoughts?

 

holy sh*t. i thought that was an additive for oil
