HELP! Problem with coolant cover and coolant refill
So I have this coolant leak around a metal plate on the engine block close to where the transmission meets the engine
Pic of the plate =>
I removed the plate and about 1.2 gallon of coolant gushed out . I caught almost all of it.
What's behind the plate =>
Now I'm left with TWO PROBLEMS:
1) Per the Porsche catalogue, there is a gasket between the plate and the engine block but I don't have this gasket at all and my engine is stock.
Left to right, new gasket, new plate, old plate. So should I add this new gasket in between or just replace the old plate with the new one? The old one worked for 6yrs afterall =>
2) With a full coolant tank, how do I refill the coolant?? Turn on the engine momentarily and the coolant from the tank should be sucked back to the engine? Any insight or tips will be much appreciated!

It was leaking that is why you took it off. Porsche makes updates all of the time. Put the new gasket on with the new cap.
Get one of the vacuum fill systems. That way you can be sure most of the air is out when you refill the system.

Re the vacuum tool, does it work if I still have significant amount of coolant in the system or I have to drain all of the coolant before using it? Our car has 6 gal of coolant and I have drained about 1.2 gal so I still have significant amount of coolant in the engine e.g., My coolant tank is still full now. I wonder if I could just get by with the simple bleeding per the WSM.

Thanks, Frank. Yes, I also figured Porsche may have updated the design. However, the metal plate has a simple rubber gasket around it so it's not surprising it leaks due to age (8yrs). I don't have good experience with "double" gaskets and am afraid of leak afterwards and redoing the whole thing again. Hence the dilemma.
I have used the vacuum system on the 911 and our Mercedes. If the system is not empty the tool will just spit some coolant while it is pulling vacuum. You will need a pressurized air source to use the one that I referenced.

Sorry, I did not get that from the first reading. If it has an "O" ring I would not use the gasket. Just the "O" ring. The 6 yr old "O" ring probably got too hard to contain the coolant.

My coolant cover plate also leaked, replaced it, water pump, coolant flush, tank cap all at the same time.
Used the ECS vacuum tool https://www.ecstuning.com/b-schwaben...l/003466sch01/
I ordered tool and coolant from ECS, fairly simple to use, way easier than trying to pour nearly 6 gallons by hand into the system.

Hose into engine bay is an exhaust hose for when building vacuum in the system. During that process I had it pointed down towards the floor, it just kinda sprung back up there for picture taking.
Instirctions that come with the unit are easy to follow.
Basically set the valves and run compressed air to build a vacuum in the system. Once vacuum is built set the valves to hold vacuum and let sit for a while make sure vacuum is held with no leaks. Then flip a valve and the vacuum in the system will suck coolant up from the 5 gallon bucket off coolant you have pre mixed.

Thanks to be honest it looks daunting applying a vacuum to suck in coolant it but it's sparked my curiosity.
I believe that Ahasi prescribed the value of 27PSI to start pulling in coolant?
What did you set your compressor to or do you adjust the PSI from the tool itself?

One other question, where do you set the 27hg?

Okayy so I've done some more research and I think I understand this system.
Attatch the gauge with the correct collar, connect air compressor gauge will then show a vacuum run until the gauge hits 27 Hg then disconnect line. Connect other line with the other end in the coolant bucket, open valve and watch the coolant get sucked into the system!
Two questions:
1. What happens to the air in the line before the coolant gets sucked in? Does it purge through the system and back out?
2. What happens when all the coolant get sucked in and youre at the bottom of the bucket? Do you turn off the vacuum before it can suck in any air and top the rest of the coolant up by hand? At that point can you remove the unit? What happens if there is still a slight vacuum or is that not possible?

2. Actually you turn off the vacuum even before refilling with coolant so there is no way to suck in more than the system can hold.

Thanks Ahsai, I've now got for find a decent tool. Here they seem to range from about $60-$400.
