Expansion Tank swap

Great post on the expansion tank. I was really hoping I could do this without getting underneath the car or removing the fan and this confirms it. Question for you; how much fluid do you lose when you pop off the tank? Also is it worth replacing any of the hoses or anything else while I'm at the tank?

*** there is a bottom clip... left side of the tank by the fan.. if u look down with a light you can see it sticking half out.. reach down and pull to the left.. or use a long flat head to do it.. *** there is a total of 4 clips to remove the expansion tank excluding the sensor clip. 2 on top..1 on the side.. and 1 on the bottom.. you do not have to remove the sensor clip if u remove the 4 clips.. then u tug up and out the sucker goes.. once thats done u can get to the sensor a lot easier.. never had to jack the car up once..

oh and as you can see i removed the filter to get acess to the tank.. hope adding this to the thread helps
