I replaced mine last week, 98 base with 235000 miles. Here's what worked for me. Access top of engine so that a trouble light can be dropped next to the Air Oil Seperator, it may be neccesary to remove the upper breather tube for room. Jack the car and remove the extruded aluminum struts and the plate under the transmission. This will allow reasonable two handed access to the tank connections in the engine compartment. I drained only the tank on my Boxster and that worked for me. Looking up at the manifold connections you will see two short hoses about 3.5 and 4.5 inches long. On my car they were nearly petrified so I sliced and removed them, replacement hoses two different diameters were fabricated from hose from Autozone, $5.00.
With those hoses out using cable clamp pliers the oil fill tube clamp and the main outboard coolant hose clamp are accessible. Disconnect the outboard coolant hose from the tank nipple.
At this point the tank can be removed from the trunk, this is where an assistant would be very helpful, note: be careful with the oil fill hose connection is easily damaged if it is brittle with age. The upper small hose can be disconnected from trunkside. An assistant would be helpful maneuvering the new tank in as I think I recall the oil supply hose and manifold nipple have a tab and slot. PM me with any questions.

My replacement tank arrived yesterday and one of the guys at the shop is going to give me a hand and he's replaced one before and has all the right tools so hoping for a relatively easy R&R . I'll report back the results .

Sounds like a plan. Good luck to you.
Since I changed mine I have noticed the temperature comes up to a tick above 180 degrees and stays right there. Course it's been a little cooler here in Michigan.

UPDATE : Today we replaced the tank , with the expertise of a mechanic we had it 100 % done in 3 hours and there was cleaning of some stuff and a fair amount of talking We did it primarily from underneath , a car lift is invaluable for this job . Removed some plastic panels and the aluminum main plate and supports . And having the proper hose clamp tools was a huge time saver .

For now keeping the trunk carpet out so I can monitor any leaks in the trunk . Drove it home 12 miles and trunk is bone dry . We did not vacumn the system as we only drained the tank and pinched off the coolant line so the system wouldn't drain from the front . Filled the tank halfway between the MIN and MAX lines and I will monitor if any additional coolant is needed . I'm glad this is done and hope the new tank lasts for many years .

Hey Guys and Gals I also need to replace my 2000S tank. Looking only at the OEM version but it seems that there is a big price diff between the 3 suppliers that are always mentioned on this forum. Is there really a difference. 50 bucks can buy other parts and they all say OEM or original? Thanks Mike
