Replace the thermostat and the water pump, still having overheating and high idling problems...also the radiator fans weren't working. Replaced the temp sensor, fans stay off. Take the temp sensor out, fans kick in (?) Wondering if it's more electrical than mechanical and I'm looking into replacing the relays.
