Check your serpentine belt as well as your water pump. Could also be the blower motor or your in-dash heater control unit.

Heater not blowing heat only cold


Check the coolant level. It is common for the intake gaskets to leak causing the coolant level to drop. The first thing to stop working when the coolant gets low is the heater. Top off the coolant and determine where you are leaking coolant whether it be the intake gaskets, hoses, radiator, water pump, etc.

If the coolant is full what does the temp gauge say? Once the vehicle is warmed up it should read around the 200 degree mark. If its below 190 than the t-stat is stuck open. Replace the thermostat.

If both of those are fine and the coolant looks like mud than your heater core is plugged. You can try back flushing it with a water hose. Remove both of the heater core hose and use a water hose to flush out the heater core. This may take several tries before you start to feel some heat.

Dash temp guage goes to red on 2000 ford focus dohc zetech


Because you have done so many repairs already I would most likely say that the gauge is defective. I would use a manual temp probe and probe the coolant temp after the car has reached operating temp. Coolant will be between 180- 230 degrees. If coolant temp checks out and you can see coolant moving in radiator and the vehicle does not overheat then you will need either a gauge or a coolant sensor. To locate the sensor it should either be mounted in the thermostat goose neck housing or the intake manifold.

No heat on 2008 sienna, replace t-stat. one rad hose and one heater hose hot. other rad hose & heater hose cool


If your top rad. hose is cool and the engine is smoking hot, it probably is a blown head gasket. What does you temp gauge read ?

My monte carlo overheats when idle but no signs of a blown head gasket nor water in oil. the temp gauge will go up to half way then the radiator fans will come on. when i'm driving it will go down to


When the engine is "over heating" are the radiator cooling fans running on high speed?

Has there been any engine work performed on the vehicle lately?

Let me know.

No heat. Temp gauge barely moves, but hoses to/from core are hot


If the temp. gauge on the instrument panel is OK, test and eventually replace the temperature sender, and check the wiring to temperature sender.

Replacing the whole heater core is not a simple operation, test sender and wiring first.

No heat


Sounds like you have a clogged heater core. Sometimes heater cores can be flushed, but more times than not, it has to be replaced. If you've replaced the thermostat and your lower radiator hose is always cold, chances are it is the heater core. Hope this helps! Have a great day!
