Upon replacing my thermostat, tested the car and everything was fine. While driving later on afterwards the car shut down won't turn over and steering got tight. Is it possible that the power steer
Personally, I cannot think of anything you could have done while changing the thermostat, that would affect the car running and then not starting. If the car won't even crank or turn over, I would start by suspecting an electrical problem, and would start by checking for power from the battery + terminal to the power supply box under the hood, then from there down to the starter. You also need to check all the fuses and relays in the power supply box. Sounds like your problem is in that area. Let us know what you find.
