Another coolant line discussion
 

Just had my coolant lines welded. During disassembly, 2 were not tight at the glued junctions. Whew!

Sounds like you did it at the right time.

Which ones were coming loose?

Do the fittings need to come out and be cleaned, then re-insert and weld.. or one can just get the engine out and then clean from the outside and weld? Just curious..

Didn't get that info. It was from the welder who had the parts. He did a great job...sorry that they are so hidden.

Because of the epoxy residue, the parts had to be disassembled, cleaned, and then welded.

Chuck is right, you have to disassemble first and clean the glue. It's really a small effort in the grand scheme of things. There is no way you can do this repair with the pipes still attached to the engine.

Is it necessary to drop the engnie to do this?

Absolutely Pete. A lot of disassembly needs to take place to get at all the fittings.

+1 to what Chuck and Serge mentioned re: cleaning

There are 8 fittings that need to be repaired.

Thanks for the info.. !

Chuck has your shop done nething to prevent the hoses from popping out? Seems like it can be the hose or the press fittings that let's go. Mike

The hose is clamped to a thin aluminum pipe that is glued to the cast aluminum. The hose and clamps were fine. Two of the 8 glued fittings were loose. That seems to be what so many people have reported as the site of failure, and that is why I did this PM.

Timely post. I dropped the car off at Conway's last week to take care of this issue. I'm heading down to VIR and figured if I drive 12-14 hours to get there, sure as heck if one of the fittings is going to go it's going to go there.

Got a call from Ken on Monday, he said one of the fitting was very loose. All it took was an easy twist, like pulling the cap off a bic pen to pull the nipple from the casting.

A couple of pics. First shows the fitting was already out of the casting about 1/4 of an inch. The second shows the fitting with the old hardened adhesive.

The third shows the work some mice did before I got the car.

Whew....good catch! A few weeks ago, a GT3 let go at Mid Ohio and caused carnage behind him. I can't believe there is no class action suit regarding this. There are articles in Pano and Excellence, many threads here, etc.

The more i read about this PM, the more i am facing reality that I am going to have to perform this on my car soon. I am setting the car up over the winter for some track time and as much as I want to spend money on other goodies. I think i should spend it here first....... My only problem is I live in Louisiana where, to my knowledge, there are no Porsche shops familiar with this type of repair. I am in the Houston area alot, perhaps I can find a recommended shop in that area. Any recommendations concerning a shop that can perform the welded coolant fitting repair in the gulf south???? If i can't find a shop relatively local i guess i will have to travel a bit.

I used the search function but didnt find anything in my area......

Thanks for any and all info you guys and gals can share....
