I've searched and searched and have not found any videos on replacing the thermostat in a gen 4. Anyone now of any??? Just today, temp light showed up, and coolant level was low. Appeared to have leaked out from the overflow tank. Check engine light did NOT illuminate. No heat in car, so I'm hoping it is a stuck/closed thermostat. Hoping there is a video somewhere? It looks as if I will need to remove the air intake stuff to access the thermostat. What else is needed? Thanks.
