When dropping the motor to weld the fittings, replace the hoses; they are the cheapest bits.

I know of another 6-3 owner who when he dropped his motor, one of his hoses was also beginning to fail; no, I don't know which one.

I justified it as some PM on a 7 year old race car. Think of the alternative.

Seems like there are 3 hoses in back:

The two on top don't seem too hard to get to. Not sure about the other one.

are these the right part numbers for the hoses?

996-106-250-74 - ~$15
996-106-529-73 - ~$10
996-106-477-73 - ~$27

The torque solutions pipes are all straight. 2 of the pipes that I had welded were elbowed.

Also, the guy who welded my coolant pipes in said that he tried using some aftermarket pipes on another car and he didn't like them. He said he much prefers using the factory pipes. I can't recall his reasoning, but I could find out if needed. The aftermarket pipes he used were manufactured near Seattle (and sold on EBay). I'm not sure if Torque Solutions pipes are the same thing, but they look very much the same.

And Chuck Price is right -- for the 996 GT3, you have 8 pipes to weld and two of the are elbows. On the 997.1 and 997.2 GT3s, there are 6 pipes to weld and they're all straight. Why would anyone sell 8 straight pipes in a package?

Guys, please don't confuse the popping fitting issue and the splitting rubber hose issue. The first is well documented, and caused by the bonded pipes coming out of the castings, while the second can hopefully be avoided with some preventative maintenance.

As mentioned above, the rubber hoses are cheap and can be purchased from any Porsche dealer for cheap. These should be replaced every one or two years for peace of mind.

I think that you can tell if they are ripe by squeezing them with your hands to see if they are soft or weak. When you open the deck lid, they are right there, one on the left, and one on the right.

The aftermarket fittings are completely -unnecessary-

Ditto that. Nothing wrong with the OEM fittings... they just need to be secured... as in NOT GLUED!

We all need to be hyper vigilant on inspecting the accessible hoses and probably just replace them every 2-3 years.

Cheap insurance, and it also allows the 'hmmm, what else can I do while the engine is out?'

You can replace the two clipped-in hoses without dropping the engine. They go from the engine to the aluminum hard pipes on the chassis.

These are the ones that are most prone to failure.

^ nah. Only need to drop it to work on the fittings. You can reach the hoses discussed above without dropping the engine. They are actually pretty accessible.

Why has there not been a class action suit on these coolant fitting failures?
