Last week we upgraded a 1980 Mk1 Scirocco 9.4″ non-vented to 10.1″ vented brakes from a 1988 Mk2 Scirocco 16v. We also upgraded the brake lines to braided stainless steel and ran a new brake hard line to the master cylinder that was seized while doing the upgrade.
The other day this Porsche Cayenne received an oil change, brake flush, and coolant flush. When this Porsche Cayenne was in for an oil change we did our courtesy 30 point inspection on it. We found that the coolant was only good down to 0ºF, but it should be -22ºF or lower. We also found that the brake fluid had a moisture content of 4% and over, which should be much lower, around 0-2%. This means that the antifreeze and brake fluid needed to be changed ASAP before the upcoming winter.
We started by draining all the old coolant / antifreeze out of the Porsche Cayenne. We then hooked up our coolant machine and flushed good coolant though it until it was a nice pink clean color. This Cayenne uses a special coolant that is imperative to use, or else other damage may occur. Green over the counter coolant / antifreeze should never be put in these Porsches. If the wrong coolant is used, the chemicals can eat away the aluminum in the cylinder head, radiator and heater core, this will cause corrosion. Using the wrong coolant / antifreeze will cause problems down the line such as clogged radiators, damaged heater cores and damage the water pump, among other things.
Next, we flushed out the brake fluid. This fluid should be the color of honey and not be dirty what so ever. If there is dirt or moisture in the system, it will decrease braking performance and brake down the seals in your brake master cylinder and calipers.
