When is this done (20K, 40, 60) and do I use the same Porsche coolant/antifreeze on my Cayenne TT as I use on my GT2?

Thanks

 

You should do yours NOW since you lost it on the Mexican highway.

 

The comment is funny, not the fact that it happened to you dr_jitsu

 

I just replaced mine. My turbo is 5 years old and the fluid went true so many heat cycles, I think it's cheap insurance for summer traffic.

 

The manual says lifetime fluid- did I miss something or am I just naive?

 

Yes, old fluid from GT2 is on hwy 59 now...wondering if I should change CTT...Porsche says lifetime, but I have heard that ater 5-6 years rplacing is not a bad idea.

 

Right radiator hose split ?

 

Correct.

 

All porsche's use the same coolant , just mix with about 50% water with the same 50% coolant and you will be fine.

 

Same thing happened to me at the track, if you look closely at it when the engine shifts it actually slams that hose up against the motor mount. I bet if you look at half the hard driven cars on this forum they have marks/indents and will be experiencing this soon.

 

I have blown the vent hose off my left front radiator to the point where I had to change to the "updated" hose.

 

I hear that the hose is also compromised whenever you have to drop the engine a bit.
