yes i did flush the whole cooling system, i think i did bleed the thermostat, but i might of done it wrong.how do i do it. and i have told that my valves are screwed, how much is that to fix, and what parts do i use,but it wanted to heat up before i put the thermostat. please help one problem is if the car is on the fans wont turn on, if i turn off the car and then turn it on then the fans kick in. i think the car heats up with is off. thats why i bought the fan switch so i can manually do it when it is on, so it can remain cooler, but now it wants to heat up no matter if i put the fans on
