Radiator R&R

I have a 2008 599 GTB and I discovered a small coolant leak at a weld on the side of the radiator. Does anyone have experience removing and replacing the radiator? Any cautions or suggestions that would same me time and money would be appreciated.

 

Update:
For the fellow DIYers... It took me about 2.5 hours to remove the radiator with only a couple of frustrating parts. The radiator side support mount is the hardest part, and that alone took me about an hour to remove the two so I could pull the radiator out the top. I think if I had to do it again I would look into removing the headlights to have better access to the bolt that goes through the mount to the side tank of the radiator. Now the next step to see if my radiator shop can repair the leak.

 

It's not pitted but it appears to be the weld between the core and tank.

I can't find the coolant spec for the 599 and the closest I'm getting is the BMW blue or Zerex G48 or G05, do you have any suggestions?

 

I am ordering a new radiator...

Another question on a related topic. I found online that the cooling system holds 19 liters (5.1 gal) of coolant. I was only able to get about half of that out when removing the radiator and I even removed the thermostat housing and blew air from my shop vac through the system. Where is the rest of the coolant hiding, or is the 19 liters wrong and it's somewhere around 10 liters?

 

I was guessing that the heater core may be holding some and that is why I pumped air through the system. I don't want to mix coolant brands or types, so any suggestions on how to get the coolant out of the heater core?

 

That would work if this were not a Ferrari 599. There is no radiator drain cock or radiator cap. The lowest hose on the radiator is not at the bottom but about midway up the radiator and that causes a problem with draining all of the coolant without removing the radiator or turning the entire car upside down. Even if I did flush with distilled water, now I have the problem of getting rid of all the water in order to get a correct coolant mixture ratio. Thanks for the input but unless you have actually performed this job on a 599 you may not be able to fully understand the process.

 

Yes, I'm aware of that and thank you for your input. What I am looking for is someone that has actually done this on a 599. After taking out the radiator, only then was I only able to turn the radiator sideways, upside down, and repeating this in order to get another gallon of coolant out of it. Also, by opening the heater core bleed screw, and turning the heat to full on with the ignition on, I was able to get another 1/2 gallon out. As of now I am still about a gallon short of the 19 liters/ 5.1 gallons the system is supposed to hold. The WSM is limited to the information on this procedure, so that is why I'm looking for someone that has experience with completely draining the cooling system and recovering somewhere around the 19 liters / 5 gallons of coolant, so when adding the new coolant, the types/ brands are not mixed and have the proper ratio.
