Actually, it is pretty easy to do. remove the glove box assembly. the case cover is right there. remove the 2 heater hoses under the hood. remove the inside cover screws and the core unbolts and comes right out. It only pays 1.2 hours in a shop. And you don't have to mess with the A/C system.

How do I reattach the adjuster spring to the self adjuster pawl on a 1991 Ford Explorer XL rear drum brake?

Put the adjuster in last. That is how I do it. It should be no problem to spread the shoes far enough apart. Then adjust til it is a snug fit to get the drum back on.

No heat after changing thermostat.

remove the heater core lines the two hoses that go to the heater core, take a splice tube either metal our plastic your part store will have either one. take the splice tube and install it in one of the lines add some hose to that tube make the hose long enough to run out side of the engine compartment and on to the ground. take the other hose and install a flushing tee, hook up to a garden hose and trun the water on . what you are trying to do is flush the heater core , you are also looking for blockage off the heater core, if you little to no flow i would suggest replaceing the heater core
