Borland, I don't understand how its incorrect? We looked under the car yesterday when I was at my mechanic's shop and it does the exact same thing that the diagram shows. It's also that one for sure. the dealer is the ONLY one that supplies this hose too and they want $91 for it! To replace it also requires removal of the fan shrouds and electric fans to get to it....Definitely something I can't do without a rack

Nope. That hose can easily be removed and installed without removing the radiator and without a lift. BTW I had my ex's re-manufactured. Good hose place (no crimping, just welding) re-made it for 40 bucks. With a far higher-rated hose. Caveat .... really stiff stuff does not like to bend.

Mongo

Heinrich, I'm going to get a hose made actually, there's a company that does business with my dad's work who can make another hose with the proper bends. BTW, how do you go about removing that hose and reinstalling the other one without having to remove the fan shroud and everything? It's so tight in there as you can see from the pictures.

It's no biggie at all Andy. If you remove the upper rad hose you will have better access. Here is a VERY important caveat.

Do not mix ATF and coolant. Do not mix engine oil and coolant.

Keeping that in mind, undo the cooler lines and remove the fan shroud.
Now, undo the hose we're talking about on the front and rear of the rad.
It is now 100% loose and you can wiggle it at will. Remember that it doesn't need to come out in one piece either, but it can. It is a big G .... just wiggle it along the passenger's side of the engine bay (you may need to loosen the coil but I don't think I did) and it will clear.

Mongo

So you defintely have to remove the fan shroud then? Damn! looks like my mechanic's gonna do it then

heinrich

Dude. Do it yourself.

Mongo

man I thought it was a tedious job to do it on my 944 when I had an electric fan die on me, I can't imagine what its like on the 928. Plus the holday season has put a big damper on my time to work on my cars Which is also why the 928's been sitting, but no more sticky lifter syndrome. Is it really hard to remove the fan shroud though? I've never really done anything serious on the 928 with the exception of a heater valve change and a transmission pan gasket...which was a little messy. I looked like Mike Myers after that was done with all that red fluid on me

Mongo

ok screw this, I wanna do it. I'm not spending 250 dollars just to replace a stupid leaky ATF line. Does anyone have the procedures to remove the fan shroud and anything that would help me gain better access to the hose??? I know the coil is in the way there and I can take that off but what else? PS if you have a shop manual please PM me.

I replaced this hose on mine so I'm quite familiar with how it is installed. I bought the new hose from Porsche, however you could use the existing fittings and new hose clamps which would work just as well. I don't know who sells metric hose, but you might be able to stretch something on.

From my experience, the hoses are shown cross connected in the PET. Like I said, you can fit it up as shown, but it fits much better the otherway.

On the radiator cooler side, you'll see a large union nut which takes, I think, a 1-1/6" open ended wrench. Taking off the fan shroud makes removing this nut much easier, however overtorquing the nut could result in damage to the radiator which could be expensive to repair. Also, you really can't counter hold the cooler while loosing/tightening the union nut; the cooler nut is just to compress the internal tank/cooler gasket.

Mongo

ah ok so you're really saying that the hose thats leaking is connected on the upper part of the trans cooler?

EDIT, hey Borland in regard to the removal of the hose, how easy is that fitting to break off the radiator? I'm not taking any chances, but I"m sure holding the wrench as firm as possible to prevent counter turning it will help somewhat. was yours fairly easy to remove or was the sucker pretty torqued on? Would you reccommend an application of anti-seize on it just in case for the next time?

borland

Yes, the short hose. You'll need the full leverage of a standard 1-1/16" combination wrench which is about 12" long. However, I can't remember if it's a 1-1/16 or 1-1/4" wrench that fits the metric union nut.

You shouldn't have any corrosion on the union, so I'd say penetrating oil won't be of any help.

heinrich

mine slipped off like butta

They are Behr radiators and you can downoad a very large Behr on line catalog (8MB?) which has poor quality/definition drawings of all their radiators incuding the ones fitted to 928s, maybe it would help you to check out your radiator spec.
