original issue sounded like thermostat but now that you have lost power i would have to say thermostat, blown head gasket, and warped head
to check thermostat find and remove place in pot of boiling water the see if it opens, then to ice water to check if closes.
the only way i know to check headgasket and head is to check oil and water. oil will have water in it, and water iw have oil in it

Red this article:
Eventhough the level is right, the fluid might need replacing (every 3~5 years and 50.000-100.000 miles).

Testimonial: "good spot on advice "
If its the electronic unit,check the main fuses near the battery,also check the wiring connectors at the powersteering pump for loose or corroded plugs.If alls ok,you will need a diagnostic machine to read out what trouble codes are in the units memory.good luck.

well the quad driver may not be at fualt and most likely is not.
there is a fualt line that the computer uses to monitor for fualts but the thing is one line monitors four different things and the code is to get you in the general area but not to the exact fualt. so from here you need to test for failed components. that code and the quad driver monitors the a/c , evap solniod , egr solenoid and coolant fan relay. the fan relay and egr are the most common i see all the time. and with you having an isssue with that coolant light i want to say check the fan circuit.
let me know if you have more question thank you and good luck
