what causes vehicle heater to blow hot only when engine is reved up.
When your vehicle is in motion and driving down the road, then engine coolant temperature tends to get hotter on the engine earlier it gets to the radiator, so the heater will naturally estrus up more when driving around. Offset check the engine coolant to make sure that its full. Superlative off the coolant if its depression.
Ken Mattson, owner of Len's Automotive in Bellevue, Wash., says a car heater can cease working for a number of reasons, including: A depression antifreeze/water level in the radiator due to a leak in the cooling organisation. A bad thermostat that isn't assuasive the engine to properly warm up.
I may also ask, why does my rut only work when I rev my engine? You may have a clogged heater core that may be prohibiting the outer linings of the heater cadre to get hot. Equally you know, the heater cadre is a series of tubes that the coolant runs through that generates the heat from the warm coolant after circulating through the motor.

Hot coolant from the engine passes through a heater core, which looks and functions a lot like a small radiator, and a blower motor forces air through it. Information technology's too the reason that a plugged heater core, stuck thermostat, or air in the cooling organization can all cause a car's heater to blow cold.
Why does my rut go cold when idling?
The engine makes very little oestrus when idling, and if the thermostat does not close, the engine coolant temperature may drop low plenty that yous'll get no oestrus from the heater core. If the coolant level is depression in some cars, the water pump may not provide whatsoever period to the heater core at idle.

Why is common cold air blowing when the rut is on?
Your furnace may be blowing common cold air because the filter is too muddy. A dingy air filter blocks airflow over the furnace'southward heat exchanger, causing it to overheat. When overheating, your furnace can trip a loftier limit switch, causing the furnace burners to shut off so that the rut exchanger does not crack.
