[QUOTE="FJM, post: 363439, member: 55030"] I do not know how old the thermostat is. The hoses are working though as you describe. The back 2 hoses (in and out of the heater coil are very hot). I lost a lot of fluid when I disconnect the hoses from the water pump (behind the alternator). for the back wash (got some nasty stuff out of there). I filled up what I could directly thru the radiator cap but it did take alot..so it seems. The reservoir is where it's suppose to be. I know it has to be low but no fliud seem to be getting to the engine which makes me thing the Thermostat is not opening. The heater coil only has water in it from the back wash... Thermostat? I'm gonna let it Idle for a while and see what happens. You previously mentioned a temperature door control motor. Do you mean blended door actuator? Thanks i [/QUOTE]
