prestone coolant

[max_asdf]

interesting points here:

i called the dealership, the parts department guy said porsche coolant is not compatible with any aftermarket coolant, prestone included.

I then called the service department of the same dealership and the person said it was fine to top up with same/similair color coolant as long as the coolant added was not green in color. the added coolant had to be the yellowish/orange color.

I then followed up and tried to book a coolant flush appointment, and they refusued it, as the coolant is lifetime and they dont do or advise any flushes being done.

mentioned to them my situation, as i only topped up from min to max, they let me know the min/max only measures the coolant overflow tank is approx 2L, while whole coolant tank is around 16L. so it should not harm anything. are these figures accurate? Havent got a chance to check my manual yet.

I am rather confused now. any more insight into this?

called another dealer part dept, and he said the same thing that no other coolant is compatible with porsche oem coolant.

2 vs 1 right now....

Max,
This is my 2 cents worth.PPI said non Porsche coolant. Comes across as kind of pompous!? A year later I thought I am driving a Porsche. It deserves the best. Bought Porsche coolant and (distilled water ?)and supplied it to my indy who installed it. I don't cheap out on Box. Oem only for me....

not really about costs here for me, want to find out if the mechanic adding non oem coolant did damage to anything,

and figuring out if i really need a flush, if i dont need one, i rather not do one.

no, it hasnt been clearly answered. if you read my previous post from the dealership, the same dealership is telling me it is OK and IT IS NOT OK to use prestone.

they are also refusing coolant flushes..

It has been, however you are not seeing it. The parts guy is correct, you should not mix brands. The service writer is also correct, if somewhat vague in how he is phrasing it; he appears to be talking about the Porsche coolant by color (e.g.: Don't use the green, use the later pink).

And just as a reference point, in general, service writers are the last ones to ask technical questions; most end up on the service desk because they lack the skills to work in the shop. Parts guys, on the other hand, learn from experience what works and what to avoid.

And if the dealer does not want to do the change out, you are money ahead as doing it yourself is one of the easiest maintenance projects short of an oil change on these cars...........

Lifetime? I put this out-of-warranty advice in the round filing bin. The same one I used to file "the IMS is a lifetime part, why do you think they made the 05-08 IMSB non-extractable? Life time part buddy, no need to worry".

Wayne Dempsey in "101 Projects for your Porsche Boxster" recommends changing the coolant every two years. I plan to do the coolant cap, brake fluid and coolant at the same time going forward.
