My old one after the first difficult attempt to lift it upwards (attached on the backside and passengerside on long flat hooks) came out quite easily after that point.
My new one was both INCREDIBLY difficult to get on I have a feeling I'm going to need leverage just to get it off if I ever need to in the future.
Just leave everything on and fold it over and rest on the engine. - also pay special attention to the engine level when putting in the engine side long bolts. They cross thread REALLY easily - should be able to put them in by hand a few turns first.
