a question for JFP regarding a 911 (997)

Both the coolant tank and the AOS are a bit of fun on a 911 variant. There is no real access thru the rear bulkhead, everything needs to be done either from under the engine cover or beneath the car. Yes, you will need to lower the engine a bit to do the coolant tank, it also makes the AOS a bit easier as well.

Don't overthink the process, your Quick jack and lift table should work fine. Work methodically and double check everything is back and tight before you put it back up.

Thank you JFP!

The FCP Euro DIY, also mention that by removing the coolant tank, you will have a better access to the AOS, therefore both will be replaced at the same time.

I saw that you need to remove both sides of the intake runners but the air conditioning compressor can be left alone, is this correct?

Thank you in advance for sharing your expertise!
