Found my coolant leak 😐

OK. Removing clamps... bring the hoses into the trunk... etc.

Couldn't those hoses on the engine side just be cut. In half. And replaced as part of the install of the new tank?

I'll read about guys replacing their AOS... getting all hung up on removing the bellows... the rubber part at the very bottom of the old AOS. It can be a pain to get the clamp off. Me? I just cut mine in half for it was going to be replaced anyhow.

So... along those lines... couldn't those engine-side hoses just be cut close to the tank... remove the tank... toss the tank... replace tank including new hoses?

No? Incorect? Am I missing something?

I wondered about this approach. Must be a problem because I'm not finding much on it.

Thanks for all the tips. I'll post my progress.

Definitely get cable pliers. I found taking old out is not the headache, it's getting all the clamps, oil fill tube on after the new is in place. Those items on the engine side of the trunk wall. Basically laying under the car and using the cable pliers to re-attach and clamp everything. At some point this part can't be avoided. The oil fill tube will be potentially brittle by this time in it's life

Got me engine uncovered. Thankfully it all fit through will my top in place. After looking at the inside I see what a tight fit this is. Quick question though. What's this bracket? Seems to serve no purpose.

JBauer,

I believe it is to hang the engine from the top while removing the engine/gearbox mounts on the bottom (at least it is what I use it for on my 987)

I did this job two summers ago. I posted what I learned here.

In my case I had no luck pulling the tank into the trunk to disconnect the hoses.

In the engine compartment the tank has rubber hoses that run forward 4-5" and then attach to hard metal lines. Instead of disconnecting the hoses from the tank manifold I disconnected them from the metal lines. They are much easier to reach and you can sort of see what you are doing. See the linked post for more info.

Also get your self a set of the cable actuated clamp pliers. They come in handy.

It’s not a very difficult job, but it sure makes you wonder about the over-engineering and logic(?) behind the approach that was taken in the coolant tank design.
Way over complicated.
I jacked the back of the car up rather high to avoid air entry into the open lines.
The cut up the old tank with a RotoZip tool and disconnected the lines from the leftover flange after pulling it int the trunk as much as I could.
Remote hose clamp pliers were a godsend. They helped in replacing the oil filler tube which I ordered for this job too.
It’s in the damn way and was brittle enough to break apart with a mere sideways glance. I’m glad I put it on the parts list.
I also removed the underside diamond plate to reattach a couple of the lines; some were too awkward to connect from above, and yes, stainless steel worm drive clamps were used instead of the originals. There’s a special place in hell for those things.

That's the route I'll be taking.
