Hi Sean, Your best source of information is a Haynes manual. Haynes is the information resource for the DIY enthusiast

obviously drain oil first , the oil pan is held in place by a series of bolts around the edge so these need undoing then the pan cxan be gently prised away from engine block as will have the gasket sticking in places , make sure you have a new gasket and oil filter before commencing this job as may have to wait for gasket if not stocked at your local parts store,when refitting tighten the bolts a little at a time so the pan is held in a level position and not bent or not sealed properly , dont need to be very tight 40 ft/lbs would be plenty of torque

YOU HAVE TO DRAIN POWER STEERING PUMP FIRST THEN YOU HAVE TO REMOVE ONE OF THE RACK AND PINION LOWER LINES TO DRAIN OUT FLUID.

If you want it to work, see a technician. If you have no problem riding without it, go ahead.

the shifter solenoid is bad

Where is the gallon of 50/50 going if no leaks and apparently not into the oil? Is it going out the exhaust which would be a bad Head gasket failure? So Some boil over due to overheat? Take the coolant tank cap off then start the car and see if bubbles, maybe steam eventually. If bubbles, they are probably the leaking combustion gases leaking through the Head gasket. Sometimes, retorque of the head bolts will slow the leak down. Otherwise need gasket replacement and possible head mill if it has "warped" or Junkyard heads that are good. You can confirm head gasket leak and location by a leak down test. You may be able to borrow tools from some of the auto parts stores. Have you used "leak stop" in the radiator? Sometimes that will block radiator cooling channels and cause overheating. Hopefully, that is the issue and a radiator replacement the fix. Could be a bad water pump, but if you get heat that is probably not the problem. I did that to a Chrysler many years ago and wife's car! Hope this helps.

Bad switch
