I shouldn't have to because I have the front bumper made of tubing which is higher than the original bottom of the bumper. It should give me enough room to stay off of the plastic bumper cover.
I've helped on a couple different MSP FMIC installs. Since you have no A/C, you will have a much easier time. The powersteering cooler that gets moved looks like a Red Bull can with 2 lines going to it. If you loosen the fastener from the "frame rail" you can slide it out of the way pretty easily.
