Default Replacing Coolant Overflow Reservoir

I've searched plenty and read fragments about it, but never got the clear answer I was looking for.

After removing the battery, what is needed to remove the reservoir?

If there are bolts there, what kind?

Basically my car is a bit of a walk away and would like to know what to bring to be able to do this without walking back and forth. Thanks in advance guys!

The only thing holding that in is the battery mount bolt, and maybe one near the fill neck (I honestly havn't looked since i bought a spare one that I need to install). Just remove the hose that goes into the reservoir, (right below the battery) and it should pull right out. Of course, this is for my 98 formula, anything older probably has a different tank)

There is one 13mm bolt that you have to remove and ofcourse disconnect the hose.

You have to disconnect the overflow hose and then pull it out of the tank. I thought there were then two bolts holding it down, which can be removed with a socket. If I recall correctly, there was one sheet metal screw holding a tab down as well. Then that should be it.

When you remove the tank, be on the look out for sheet metal screws sticking out of the wheel well. They should have plastic protectors on them. If not, you want to make sure not to rub the new tank on one when putting it in, otherwise you'll get a puncture.

GM also recommends washing your new tank out with diswhashing detergent before installing.

Alright, thanks a lot! Hopefully I'll get on this tomorrow, otherwise I'll keep leaving orange spots wherever I park .

Update: I got everything apart, after a wrench failure I might add, and there was so much corrosion and rust that the poor little bolt is surrounded. So tomorrow I'm going to go get some PB Blaster and coat it in it, hopefully that will free it up.

Anyone have any other suggestions?

Try a big breaker bar, and use a quick motion to break her free!
