Flushing Coolant (What Kind Should I Use?)
Hey, just bought a 996 a month ago. Love the car so far but I have noticed the water pump leaking. I am going to drain and flush tomorrow. I am replacing the water pump and thermostat while I'm doing it. I just need to know what type of coolant to use. I looks like it currently has green coolant in the car right now. No clue what kind it is... I can get pentofrost sf coolant locally tomorrow. Looks like I will need to buy 8 1.5 liter bottles giving me half a bottle left over when doing 50/50 with distilled water. Will cost me $140 roughly for the coolant alone. Should I do this or should I use a cheaper coolant alternative? I plan on completely flushing the system either way with this tutorial

Any options? Seems like a lot for coolant on top of buying the new water pump and thermostat. Open to any thoughts. Thanks

I just bit the bullet and did the P coolant. I figure its once every 10 years so what the heck.

If you do a search on this site you will find several threads on this issue. I read many when wanting to do a flush and ended up with the P coolant. With that said, I also read that others use an Antifreeze/Coolant - Organic Additive Type (OAT) with an aluminum-protecting inhibitor such as "Extended Life Antifreeze". Some of the types I found used by some are:
Havoline Extended Life
PEAK Global Lifetime
Pennzoil DEX-COOL Extended Life
Prestone Extended Life
Zerex DEX-COOL
Again, this is info I found on various threads in the past and am not making any recommendations. Just wanted to pass on some info I found here.

FWIW, a while back I was reading up on Pentosin in connection with power steering fluid. I recall reading that Pentosin used to manufacture all OEM fluids -- including coolant -- for VW. That was quite a while ago, though, and may no longer be the case.

Porsche does not make coolant - the fluid is rebranded from manufacturer like pentosin. SF is what is recommended on the pentosin site- I can find those 1.5l bottles for around $12 at pepboys - and you can take any left over ones back to the store. I don't think I used more than 5 bottles plus the distilled water when I did my water pump (pierburg pump and whaler thermostat from pelican)

I've used Pentosin Pentofrost SF ... it's pink. I have no idea if it's the same formulation as the Porsche coolant, but it's definitely pink:

But if you're in a situation where you need coolant right away and there's not a Porsche dealer available, Pentosin may be the only option -- last I knew, you can get it at Autozone. So it might not be about saving 10 bucks, just about necessity.

I know I am new to the Porsche world but, not to cars. Why no mention of Evans waterless? I ran it in my 87 BMW M6 and loved that no pressure was required in the system to raise the boiling point. I first learned of it watching Jay Leno's garage. It's all he uses in all his cars.

I'm not enough of a coolant guru to have any idea what benefit it would provide in a 996.
