Coolant flush?
My Porsche dealer says that the coolant in my 2005 Carrera S is 'lifetime' and doesn't need to be flushed although it is original. I admittedly over-maintain the car to some degree and am inclined to go ahead and have them do it but if the dealer is right I hate to spend the ca. $450 they want to do the job. Your thoughts?

Your water pump will die eventually. It's common on 997's. Flush the fluid when that happens. Or proactively change your WP and flush the fluid if age/mileage is high enough

Ask if a service bulletin has been issued changing the Factory spec on life time fluid for cooling system.

I’m in the same boat. I have a 987 with the original coolant. I’ve thought about changing it but then decide not to based on the “ lifetime” recommendation. I’m not a fan of throwing away money because I am paranoid or uninformed. On the other hand, being cheap and foolhardy isn’t appealing either. LOL One thing to consider,IMO, is also changing the rubber hoses during the flush. Rubber deteriorates over time. We are looking at 14 years on 2005. I’m sitting on the fence there too. Sometimes you just have to suck it up and replace stuff before it becomes a problem. In fact, I just bought new tires last year because of age not wear for my TR6. In in any event, I wish I could help but I have the same conundrum. |
"Lifetime" can have a lot of things of meanings... on a personal note I'm 71 so there's that. :)
Well back to our cars. I have a 2009 997.2 C2 with just barely 24K miles, so at this rate lifetime could probably mean forever. But realistically speaking, having 10 years of the same coolant flowing through my engine is not my idea of good maintenance practices. Worse yet, it's probably a source of built up electrolytic contaminants that will affect the overall cooling system and specially the failure prone water pump. So in my case I've scheduled a visit with my independent shop for a flush/change and thus create a new "lifetime" for the coolant. |

My 08 has 28k and original fluid. The indy I am going to said they do not see problems with the coolant and do not have a change interval recommendation. As with others, they recommend prophylactic water pump replacement around 50-60k depending on age.

The water pump will fail between 45,000 and 65,000 miles. Do the coolant refresh then. Sometime before or after this second water pump fails, the coolant expansion tank will crack and that will give you your next opportunity for the coolant refresh. No need to do it until one of the other cooling system failures occurs.

Thanks to all for your responses.
My car currently has 25,000 miles. I drive about 4,000 miles per year. So if I wait for a water pump failure, assuming it occurs at about 50,000 miles, I'm looking at another six years on the original coolant. I think I'll have them flush it in the spring and then change it again when/if the water pump or coolant reservoir fails. Maybe a waste of money right now but worth it for my own admittedly obsessive peace of mind. |

The previous owner of my car had the front radiator replaced, but the shop that handled it put just run-of-the-mill standard green coolant in the car. When I replaced the coolant expansion tank, I requested that it be flushed and have the proper coolant put back in the car. Personally, I believe when the car is undergoing preventive maintenance that involves the cooling system (water pump), it may be a time to have your car flushed. When they flushed out the green stuff, it did NOT have a nice clear bright look to it. It was very cloudy and dark green.

It's 100 bucks for coolant. What are you waiting for?
|
So, I bought my 09 4S with 50,000 miles. It now has 76,000 miles. Never before flushed the coolant fluid. Should I do a complete flush and replace?
