GT1 Coolant Pipe Prevention / Fix on 2011 GT3RS @ Shark Werks
#16
It's possible the glue that Porsche uses in the fittings is designed so the fittings
can be removed in the future. There may be some extra strong epoxy which could be
used to glue the fittings in. The downside would be if there is a leak or crack in
the fitting, removing it may not be possible. If such an epoxy is available, it
may be an alternative to TIG welding.

Only way for this to be done "100%" would be to go to the parts manufacturer and get them to recast units as one piece... Obviously Porsche ain't stepping up to the plate for that one....

does anyone know what it would take to make porsche issue a recall on this issue? has anyone talked to a lawyer and gotten their perspective? seems like such an obvious safety problem that has occurred on many vehicles. tons of documentation and evidence on the issue. you see toyota making recalls all the time. is it just down to the company and their willingness to turn a blind eye to the issue? is there a regulating body that should be notified?

And as a stop gap until you can execute this solution or TIG welding per the Excellence article, replace your coolant with water wetter & H2O in the interim. Will at least prevent you and the cars behind you from losing traction & potentially crashing on the super slick coolant dump.

Cross-posting my comments from the 996 GT2/GT3 section cause I know some of the 997 guys don't come over there often
Thank you Dan. This is a truly ubiquitous problem; we've all seen it or experienced it first hand I'm sure.
While talking to Alex last week, the topic came up as I wondered aloud about the logistics of sending in the various manifolds for you guys to do your magic. But, the logistics would be complex, the cost too high, and the hassles of crossing the US/Canada border excessive.
However, reading your post just now, inspiration hit. Here is what SHARKWERKS needs to do:
- You need to build and sell a kit with hardware, sealant, and clear instructions so that owners of GT1-blocked cars WORLDWIDE could carry out the modification locally. Heck, you could even include drill and tap As far as I am concerned... name your price!
Who knows if this will be a huge money maker but I doubt that it will cannibalize your local business, so there is no downside for you. Plus, if nothing else, think of the goodwill such a move will create and it would certainly, ONCE AGAIN, put SHARKWERKS at the top of the Porsche Performance supplier list.
You guys have my address, so please ship me the first kit

I believe in part due to everyone going public about this over the last year especially I've seen some parts/kits available so I'll chat to James about it
Last year I had Sharkwerks fix the coolant tubes on my GT2. I have tracked a GT3 and then a GT2 for five years without any problem. But i started worrying about the coolant leak happening on a high speed turn and decided to get James to fix it. It isn't cheap since he has to pull the engine but is well worth ir for the peace of mind it buys.
Thank you very much for posting this fix Dan, its really impressive to see the step by step process, and you guys do some incredible work.
Thinking into this a bit more, would it be advantageous to run a tap with the same thread pitch as the bolt your using into the cast aluminum coolant manifold in an effort to provide more bite and surface area for the red locktite to properly adhere to in an effort to reduce the likelihood of the threaded bolt vibrating or working its way out eventually?

It's a quick fix and will hold better than the glue and prevent a sudden release of all fluids, only concerns would be that the coolant might become contaminated while drilling and tapping, and that the bolt won't prevent minor leaks if glue fails.
Maybe if motor is out welding or threads would be a better idea anyway?

The adhesive around the tube acts like an o-ring to hold the coolant in, the problem we're seeing isn't the coolant leaking through the adhesive, it's the tube completing ejecting from the casting when the adhesive softens.
Ultimately, a trickle of coolant can be detected and repaired... A gusher can hurt you or others... Benefit with this method is you can back those screws out, re-glue and do them up quite easily... Downside- its going to cost a crapload if they constantly fail and the engine is continually being dropped...
Biggest problem is that neither welding or tapping is ideal... They both have their issues... And who knows which is the lesser of two evils???

I wish I could say that's true but... I've already spoken to two people with 2010s that had it happen James says although the manifold and thermostat is a bit different they do suffer from the same weakness/symptom...

I just had my Thermostate and sensor replaced under warranty. It was not the Thermostate as they replaced that first en then the sensor, I run water wetten, but hope they were gentle with my coolant hoses.

This crap bugs the **** out of me about the stupity at Porsche..... WTF get over the attitude this is just crappy engineering at it's finest. They need to step up and fix this right.
Alex thanks for showing us a possible fix.

Sorry if this is a dumb question but what do th GT3 Cups do about this issue?
