I have just bought a 2002 Holden Commodore. I checked the radiator and found it was choked with rust and mud. I have flushed the radiator, but I want to know how to remove the coolant reservoir so I can try and clean the rusty crap out of it.
First, pull the radiator overflow hose out of the side of the coolant reservoir fill neck and turn the steering wheel to the hard left to get room to get tools in. Laying on the ground undo the two screws on the front of the reservoir and screw on the frame rail, and you can then remove the reservoir.
