Like said above, the temp issue and suspension pop are your priorities.

Radio, odometer, and heater fan?

You could drive 20 years without a radio or odometer, those are annoying, bit not critical issues, and you have the summer to figure out the heater fan. Radio is a sub 100 dollar repair, go buy a cheap unit from walmart when you can afford it. It will have install instructions, and the forum is clogged with data on radio wiring with the fader switch.

Describe the suspension load pop to us in greater detail. You absolutely need to know what that is before you can ignore it. I had a similar loaded pop on my 240, which turned out to be the base of the front shock was loose on the pivot and i needed new shocks. Front suspension issues are easy to check for yourself at no cost. You need to make sure the tire isnt about to fall off.

Tell us more about the overheating, that needs nailing down as well.

If you have the suspension noise and overheating solved, the rest are "when you want to fix it" repairs, not "when you HAVE to fix it" repairs
