I installed the German tank from Warehouse33 last year and it appears to be the same quality as the OE tank.

the original motor mounts have been changed long time ago.

I�ve found the dealer to be a lot cheaper than with other marques so I typically check there first.

Is brake clean safe to use to clean up the spilled coolant, is it safe for the electrical and hoses?
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

The expansion tank on my 1999 996 coupe cracked while i was driving. The hot liquid went every where. About 1/3 of the coolant spilled inside and dripped down the headers. So I have a few questions for some of you that have done this before.
1. Is there a difference between the tanks? They range in prices from $200 to $600 on pelican parts website?
2. Is brake clean safe to use to clean up the spilled coolant, is it safe for the electrical and hoses?
Also I tried starting it up today so I can drive it on blocks to be able to get the jack under it I want to take off the tire so I can clean up the headers and under the car. When I tried starting it up, it made a rattling sound and it shut off did not fully start. Is it possible for the coolant to have blocked or short circuit the plugs or injectors?
Not sure about the rattling, but if it's been leaking on an ignition coil, that could cause the engine to run weird.
You want the tank with the part number ending in 04, as that is the latest revision.
This may not be correct for your year. Sorry.
The correct part for your 99 is 99610614756 (see
http://www.autoatlanta.com/porsche-p...section=105-20
) . A genuine one is $488 from here
https://www.sunsetporscheparts.com/o...MtNGwtaDYtZ2Fz
An aftermarket one is $232

Also get the latest CAP (I think that's what Sweet victory meant) 99610644704
I just ordered an OEM one from AutohausAZ for my MY2000 C2 - $202.49, no tax, free shipping. This would be the same one for a 99. I'm not currently having any issues with mine but I can tell from the color that its original. I might as well get one now as they're only likely to go up in price if I wait. I seem to remember reading that the R&R for this is a little easier than on MK-II models. Is that accurate?

Warehouse 33 also has them for about the same price. I'm not sure about the tax or shipping.

Yes the coils could have gotten wet. What else should I look for? Are the injector connectors exposed? Is there any other electrical hard ware on that side?
Not sure on the rattling. +1 on coolant on the coils causing rough idle (particularly if they are old and cracked).
As for sourcing a new tank, I ordered the part directly from the dealer for $138 a few months ago which looks to be cheaper than anything above, lol. I�ve found the dealer to be a lot cheaper than with other marques so I typically check there first.
Here's the link to the German tank, usually when it's branded "GERMAN" it's a genuine part with the Porsche logo sanded off.

OP, I would highly recommend ordering through Warehouse33 simply because of his awesome customer service. (I ordered my tank through him) He also offers 10% off for Rennlist users!
Doe it make sense to change out the original motor mounts at the same time? I haven't noticed any issues and even though I only have 65k on the clock, the car is 18 years old and I'm sure that gravity plays a part.

the original motor mounts have been changed long time ago. To a more stiffer brand it gives a little bit of vibration in the cabin. And I like it. I feel more connected to the car and the way it drives.

I was thinking of using break kleen instead of a water to was out the coolant. And yes it's cracked.
Getting ready to start collecting parts and have a couple shopping carts saved on your store. I thought there was no OEM style replacement for the Porsche coolant tank. Glad I stumbled upon this. Shame its out of stock currently lol
Consider yourself lucky. I've seen many cases (online) these non-genuine tanks are problems. Usually start leaking or the threads will be stripped very soon.
I have recently joined the 996 club but had to do this job when I purchased mine. Never posted, but thought I'd share my experience. '99 C4 coupe.
I went aftermarket. I followed the Pelican parts write up exactly and it was tough but I got er done. Then continuous leaks from cap. Purchased a new porsche cap, still leaked. "996 panic" set in, all sorts of bad thoughts - surely my engine is blown. I returned it and replaced it with another aftermarket tank, sure enough the threads on the first aftermarket tank were bad and would not hold pressure.
So, I had to do this PIA job twice. The second tank seems fine but in hindsight I would have just got the porsche tank initially. The second time I actually did the entire job in just under 2 hours - first time took me all day.
Just my .02. I'm an expert coolant tank replacer now - I guess I got that going for me.
By the way, this is a great forum, I have learned SO much from the owners here through my search and now my 911 journey. So glad I found it, and thanks to all the regular posters.
Welcome to the madness as they say! hahaha I just replaced my expansion tank and ordered it from Porsche. I didn't want to have to turn around and do it any in a few months. It's tempting to save a little money, but when it comes to a part like the expansion tanks, it's not something I'd recommend going aftermarket. Too many horror stories about them leaking.
I bought an OEM tank from Pelican - and two years later, it's leaking again.
Sonnenporscheoemparts.com has the real Porsche tank for $480 shipped. Best price for the 996.1 tank I've seen.
Happy to help
I just hate seeing people spending hrs installing a non-genuine tank just to find out it leaks again in a few months. The MkI tank is expensive but seems there are no good alternatives for now.
Unless you ENJOY replacing the tank, you're much better off going with a genuine tank to avoid a redo.
I agree and almost always go with genuine Porsche parts, but it's not a little money in this case. For MK-I cars the Porsche tanks are in the $500-$600+ range. I installed the German tank from Warehouse33 last year and it appears to be the same quality as the OE tank. I haven't had any issues with it (knock on wood). I don't know why some MK-I parts are 4 times the price of MK-II parts, but they are. Check out the price difference when it comes to injectors. Crazy.
