04 CTT, the coolant pipe finally burst at 100k miles and left all the coolant at costco parking lot.
have couple of questions here:
1, how long can I keep it like that. I mean I am ordering parts from suncoast, or I can get local but double the cost. I heard in some cases the coolant ate the sealers somewhere under neath and cause bigger trouble. so should I fix it rightaway with a fat bill or I can wait for a week or so till the parts come.

2, while fixing the pipe, apparently a lot of parts will be exposed. what should I "might as well" change/replace some of them at the same time? if yes, could someone give me a list?

I just fixed the "common" brake booster failure problem. it turned out the vacuum tube on the passenger side behind the windshield washer cap has a hairline crack at the pump end and a much bigger crack on the other end. porsche want $120 something for the whole assembly
I fixed it with a heater/coolant 1/2" pipe from a local auto shop. it clears the warning and everything was OKay. untill the big spill at costco this afternoon.

any input will be greatly appreciated.

 

I would just hose off the spilled coolant and it should be ok.

 

After it left all the coolant in Costco's parking lot? I guess if you want to pay for an engine after it overheats due to lack of cooling that's a suggestion.

Park it until you get the parts. Don't try driving it anywhere. If it has to be moved - get it flatbedded. Don't have a motoring/tow-plan? AAA, or some other, well - now is when you'll realize the value of one.

Driving it without coolant there is a VERY real chance of overheating and turning the engine into a useless lump of slag. It has to be fixed. I'd suggest looking into a rental until it is fixed.

So i suggested he hose off the spilled coolant..Not drive it.

 

The spilt coolant has been known to find its way down to the torque convertor seal on the transmission. The seal deteriorates and then you have the transmission fluid leaking problem.
As Tonka suggests, best you can do is try hoseing it down asap to prevent the coolant eating the seal.
The other issue with the burst coolant tubes is that it may have drenched your starter motor which will give you problems in the future.
On the other hand, it may not be your coolant tubes that cracked, it may be the T piece at the back of the engine that cracked dumping the coolant. Either way get them both changed whilst your in there.
You may want to check the turbo vent lines for cracks and possibly change the fuel tank check valve when the manifold is off as well. Confirm the ignition coils are not cracked as well.

 

thanks guys for the reply.
it happened when i got into the parking lot and someone told me the coolant was leaking .so i stopped right there. did not continue driving and all the temperature readings from the dash were in the normal range.then i got a flat bed and it is now sitting on the drive way waiting for parts.

so to sum up, I should change/check the following: correct me if i miss anything
1, coolant pipes , T connector
2, coil pack
3, trans seal
4, starter
5, turbo vent lines
6, fuel tank check valve

first thing first
how do I hose the coolant down??? with water??? excuse me for my ignorance

thanks a lot guys

 

Get ready for a REAL big repair bill... I went through this late last year on my 04 CTT. The coolant pipe rupture cost me about $2500 to fix, and then 48 hours later my transmission main seal went. The problem with that is that you have to remove the transmission and engine as an assembly to pull it apart. I was quoted $5-8k just to fix that.

Good luck, also suggest you check the Class Action Cayenne lawsuit for this.

Thanks David. That's really scary.
How do I hose down the coolant? Anybody? Help
Please.

 

With a hose - water. Squirt it from behind the intake manifold down toward the front (sort of under the manifold.)

I wouldn't rush out and buy a starter and rear seal (since the rear seal requires R&R of the transmission - I haven't heard it requiring engine removal..) and since the starter MIGHT be OK if you flush out the coolant quickly enough. I suspect the vehicles that had seals go and starters destroyed had long-term leakage that wasn't taken care of, and the coolant dried as it went past the torque converter shaft causing the seal to fail. If you haven't been adding fluid regularly you may be lucky and not have this problem, especially if you get the coolant flushed out of the area.

When you get it apart - I'd remove the starter and look for an old time auto-electrical place in your area. Used to be these were all over the US, every small city had one, with guys who knew how to disassemble/repair things like alternators/starters/generators. As these guys got older - apparently no one thinks of this as a career anymore, the shops have slowly disappeared. If you still have a Yellow-Pages in your area, look under "Auto, Electric" or "Automotive, Electric" - and if they have an add with the Bosch symbol in it, you probably have found one that can rebuild the starter for you.

Cost will be way less then a new (which is actually rebuilt) one from Porsche, and quality should be at least equal or better then the rebuilts (think actually mostly cleaned and repainted, with a cursory functional test) from places like Autozone, Kragen, big box car parts stores.

You might also check if there is a NAPA dealer in your area. NAPA generally supplies professional mechanics, and one of their product lines is rebuilt by Bosch starters/alternators. Quality is often good enough to be new (and sometimes I think they are new - just a way of not competing with dealers for customer $$..)

Yup - they list a Bosch rebuilt: https://www.napaonline.com/Catalog/R...11&Ntk=Keyword

The Bosch rebuilt is $383 - $89/core charge - so cost is under $200. I believe Porsche gets over $700. They also have some house brand rebuilts that I suspect are less expensive, but I'd go with the Bosch. Several mechanics I know won't use anything else since they hate to have to redo a job for free if the rebuilt part fails.

Good luck!

 

a one time leak on those things should not hurt anything at all..

great auto electric guy in San Diego..been here for ever Pelak auto electric..
Rolls Royce dealer brings starters to him to rebuild.

 

Seriously I love you guys.

 

take pictures

 

Uh... my situation does not match the above unfortunately. I had my coolant system pressure checked a few months before my failure by the local Porsche dealer. Tested fine! I had NO leaks of any sort before my complete pipe failure on the highway. I pulled over immediately and had it towed back to my dealer were they did the retrofit replacement with metal pipes. The dealer recommended a starter replacement since the coolant tends to ruin them eventually. Remember, the starter is in the middle of the engine and not normally exposed to water or coolant so it is not a waterproof component.

Even after all this my transmission seals went out within 48 hours. It was not because of long term leaks, but due to the pipe failure dumping a majority of my coolant directly over my starter and then down the back of my engine into my bell housing. Not saying this will happen to everyone, but it did happen to me.

just ordered everything. we will see what happened and will happen in there.

 

Does the coolant get into the Tranny? Fixed cars for a long time and have never seen leaking coolant take out a tranny.
If coolant does get in the tranny have it flushed before you even start the car..
you would need to tow it to some place to have it done.
