96 Cobra overheat issue again

i replaced the t stat 195 from ford overheated blew out of the cap . ok so i decided to drill a 1/8 hole in the tstat so coolent will pass into the rad well the temps still are highlike the m or a in normal in in hot weather . if i use the A/C the fan runs all the time but still temps are high and after i shut off engine it will blow out of the cap , today i used a hose to clean out all the crap on the front of the condenser and radiator and still tems still tend to climb , is there anyway to adjust the fan to come on sooner like at 190 , i know replacing the rad will fix that problem but ill be sellling the car soon and dont want to sink a ton of cash into it , is there a quick fix ??? will ford do a recall replacement , ? also what to do with the ratteling front calipers sheesh sounds like bolts in a can when i hit a bump , i replaced the pins calipers still move up and down . thanks for any input !!!!!!

i need to replace the pads and i did replace the pins last year ~ when i refilled the coolent after thermostat replacement i did bleed it many times i guess ill have to recheck it the dam temps just bounce around to much, drilling a small hole in the themostat will cause any problems ???? is there anyway to separate the fins in the condenser or is that a bad idea ???i did hose it out was full of crap and inbetween the rad and condenser as well , ill be selling it in a bout a month or so.
