Howdy everyone!

Just some quick background as an intro, I purchased a 04 Cayenne TT last weekend with 57K miles down in Ft. Lauderdale for use by my wife as a local daily driver. So, right now I'm in the process of de-bugging the vehicle to make it as reliable as possible. According to the local indy shop I'm using that services Porsche I've got one crushed transmission mount, the motor mounts are tired (but not bad), and they had the feeling something was loose in the suspension but they weren't sure - air struts all raise & lower the vehicle OK. From the initial inspecton it seems to run & drive OK however, no leaks or squeaks. I'm doing tires all around next week on a labor day sale (the last owner mixed two different brands of criminally cheap imported tires, I found major sidewall cracks in one tire after a 5-minute inspection!) and I've been doing some EBAY for nickle-dime replacement pieces.

My local Porsche dealer did NOT win my initial vote of confidence yesterday, I went down & made a small parts order and asked if they could pull a service history on the vehicle for me to see if I had the coolant pipes upgraded, they used the line on me that "our computer system is not hooked to other Porsche dealers and you'll have to visit each individual dealer that serviced the car for a complete history". Yeah, right. And I'm coming back to your service department really, really soon..... hear the cold wind blowing? :)

Anyway, to the point of the post. During my initial inspection, I heard and two other competent folks heard some rattling at the front of the engine. It wasn't the constant "tap tap tap" you'd get with the tired piston syndrome on the 4.5's like I've heard on the YouTube videos, but just a mid-frequency rattle of low to intermittent occurrence. Once I thought I had a whiff of coolant but I'm not sure. So, to err on the side of caution I'm probably going to do a water pump and at the same time do the coolant pipe changeout along with whatever T's I can replace with metal subs while the engine's open.

Water pump brands. I know there's multiple manufacturers out there, OEM Porsche, Laso, Hytec Debartolo, Gates, Bosch, ASC Industries, GMB, and the list continues. Anyone know who has the best QA on the pumps to hopefully stave off another failure? Granted the first pump (assuming for discussion it is the original pump) lasted 10 years, but does anyone else stand out as superior?

Also... on the coolant pipe replacement, I was considering strongly using the revised ECS Tuning kit. They seem to supply everything that's needed along with some extra, also ECS has a good reputation from folks I've talked to. So, has anyone used their kit as opposed to the one from the Porsche dealer? The ECS kit is $599 plus shipping. Here's a linky:

Thanks for input before I start shelling out major $$$!

Well, shouldn't have spoke so soon about no leaks. I had to change a bad front left marker light bulb earlier today and while I was inside the fender liner I looked down and noticed the vehicle very slowly dripping something pink from the area forward of the left wheel, also the inside of the left front wheel appeared wet. It was a very slow leak, only a few drops over a few minutes but it was definitely leaking pink. Looks like it's time for teardown next week.... sigh....

And you know otherwise how? The computers are not linked for non-warranty service repairs. Only repairs/service that is done as part of warranty service is in the central Porsche computer system. This is standard for all the euro car brands I know of. Each dealer keeps record of service done at their dealership - but has no access to anything except warranty repair records if there is work done at other dealerships.

Hi Don.

Well, before I made the request I read these forums fairly carefully for a number of hours and found references to at least one other member that apparently obtained his complete service history by making nice with the local dealer. Some of the records I do have were from Porsche/Audi of West Houston, the records are in exactly the same format as GM dealers use (both using ADP's invoice system). This is a linked system at least in the GM world, but I know I can't assume it translates to Porsche.

Just from a pure customer service perspective, the right thing to do in my mind would have been at least for the service writer or service manager to try to run the VIN to see what came up (noting your point on the warranty coverage the Carfax says there was a lot of early service visits and work done on the vehicle), but they didn't take the time to at least make the attempt. Sounds like from what you're saying the best I could have left with would have been a history for the first few years, but that would have been better then what I have now. I do know what dealer serviced the vehicle under the last owner, so maybe they will be accommodating if asked nicely.

For the dollar valuation of these vehicles it seems rather odd that dealer servicing information is not easily obtainable when apparently Porsche is capturing warranty data elements already in a centralized database. Business decision perhaps?

Are you sure it's not windshield washer fluid?

Not sure at all. I know the washer fill is on the passengers side but I don't know how the washer reservoir sits in the vehicle since I don't have a shop manual yet. I use the Rain-X orange de-icer fluid, so the color would be close perhaps and I did add close to .75 gal worth to the reservoir. I'll hopefully find out for sure early next week when I replace tires and have the vehicle lifted.

never go to a porsche dealer haha....over priced and not helpful. Sunset parts in oregon will sell at invoice +15% or something like that....and it's a porsche dealership, so they can get you whatever you need, and lookup the part # if you don't know it.

I bought my coolant pipe stuff through a family friend who happens to have a porsche dealership, and got all the pipe stuff + a few other things for 500 bucks, so 599 for ECS isn't a terrible price.

ECS is a good company, i think they overprice some stuff, but overall helpful and reasonable to deal with.

For brand coolant pump, you will be good with any of the standard brands, chances are they are the same, and multiple suppliers are probably OE suppliers to Porsche.

As for the turbo coolant T's, there aren't any OEM metal replacements for the T's unfortunately. However i know many people that have 100k+ on the OEM T's without issue. The benefit for these T's are they don't sit in the valley of the motor, so they aren't exposed to the heat that the main pipes are.

Another thing you might want to think about while in there would be the starter as well.....especially if coolant soaked the starter.

Enjoy the CTT, i have the same year, and use it for everything from towing and pulling stumps and offroad driving, to just daily driving. I've never got it stuck, even in 40" of snow......Diff locks work well.

      Hello All,
      The car has been awesome 2006 987.1 30k miles. The other day i took it for a drive and stopped after about 150 miles for about 30miins when I came out, all my coolant was on the floor. I refilled the coolant and constantly checked the temperature, initially it edged up to 180F but then settled back down to 175F and stayed that way all the way home. I was driving gently and kept cheeking the coolant level. Since then I found that I needed to open the coolant needle valve and drive around for 3 or 4 days to bleed the cooling system. I'm on day 2 and the coolant level has gone down slightly. Whenever I stop I check the floor and there has been no coolant leak.
      I am baffled, anyone seen this before?
      Thanks.

      Today while sitting in traffic I heard a slight pop on the passenger side and saw smoke/steam fly out from the passenger side at the windshield. Temperatures climbed slightly over the next 10 minutes but came back to normal as I made my way home. Upon immediate inspection, I see nothing obvious except some coolant on the ground coming from behind the passenger front wheel, and the fill cap there at the windshield junction was a little wet. There was also a little on a bolt directly down from the torque arm.
       
      I do not know the routing of the lines or what to look for once I get this all off, if I can even see where the leak is coming from. Can someone explain the coolant line routing in that area and suspected fail points?

      Turbo/Turbo S (maybe even GTS) thermostats are not the typical looking reverse poppet design I've come to know an love (hate?) over the years. The "standard" design is pretty obvious - a hole opens up in the middle against the flow of water. 
       
      On the Turbo/Turbo S it seems to be a balanced sleeve (am I correct?), which allows pressurized coolant to circulate around all of its moving parts. Sounds great, but I don't understand how it restricts the flow. Upon 1st impression it would seem to me coolant can pass right through it unrestricted, regardless of the position of the internals. I do realize the water pump sits in front of the thermostat and that the inlet(s) coming from the engine and the outlet tubes exit out just over the water pump both are both behind the thermostat. This must have something to do with it but in my mind, having both inlet and the outlet on the other side of the thermostat means the water pump isn't doing anything but churning coolant. See diagram on page 89 of this parts diagram: https://www.porsche.com/all/media/pdf/originalparts/en/E_9PA1_KATALOG.pdf
       
      Does somebody know how this all works? Your knowledge is appreciated!

      Durametric says I have a problem with the passenger side radiator fan.  Using the Actions controls to turn on the radiator fans, the passenger side fan does not turn on in either low or high setting.  Previously while replacing brake pads I removed the wheel well liner and inspected the radiator unit.  The fan turns freely when manually pushed but does not turn under computer control.  So the fan motor appears to have failed.  Driver's side fan works fine.
       
      The fan is mounted to the radiator as a unit and it appears impossible to remove just the fan without removing the whole unit, and given the tight space it appears necessary to disconnect the unit from the cooling hoses to do so.  I was hoping to avoid this and replace just the fan.  I have searched and there are numerous sources for replacing the whole unit but none (that I've found) that discuss whether the fan can somehow be removed and replaced by itself.  Does anybody know if this can be done?

      Does anyone have a solution for debris easily getting into the radiator area?  Leaves, needles, trash, etc.  Under the license plate isn't protected at all, and the openings to each side allow tons of stuff through.  I'm thinking something like the GT3 has -- mesh that fits right and looks right.
       
      Going in with a shop vac every second or third wash seems the only "solution."
