I just added a quart to mine. It was brand new back in May or June(around 2,300 miles) and I only checked it last weekend.

I bought a gal of Zerex G40 (pre-mixed) for about $23 at O'Reilly.

I will keep an eye on it more often, no need to waste the expensive coolant if a quart low is normal.

 

I've used WW since 2005, it has worked well in my cars, when I have flushed them they looked very clean. On my Vettes it did actually lower the temps by about 5 degrees. Not real scientific proof. On the Porsche it didn't lower the temps, I think the Porsche is hard coded to 194 degrees period.

 

I was under the impression that Porsche says only check (and add) when the car tells you to.

 

Just checked mine and lo and behold bobber pegged at min. I added Pentofrost E to get mid point reading. Just didn't think to check and never got a warning.

 

Bumping this for UGLYOKI.

 

WOW didn't know there was so many threads on the subject.

Wonder if there's a forum feature where the moderators could link the threads together.

They could do the same with "tires skipping" and "acorn effect".

 

 

That's a Rennlister's screen name. I don't know anything else.

 

So, after getting a message and seeing the bobber on MIN, I added 50/50 coolant/water until bobber rested on MAX. However, when resting on MAX, I never saw any liquid below the bobber. Can anyone explain why?

 

How much did you add?

The fluid is way-way down there. Get out a flashlight and look (again).

 

I added 2.7 liters. Seemed like a lot.

 

Yeah! 91 ounces. Well, at least we know when the light turns on.
