The inlet hose for your heating system is the hose that goes to the water pump area. The other hose is the outlet. These flush kits will actually work on either one though as it does go through the entire cooling system.
Should both heater core hoses be the same temperature?
When the vehicle is at operating temperature feel the two hoses, the should be the same temperature. If one hose is noticeably hotter then the other then the heater core may be partially plugged or restricted.
Where do the heater hoses connect to the engine?
Heater hoses are rubber hoses that circulate engine coolant to and from the heater core, which is the small radiator that provides heat for the cabin. They typically extend from the engine to the firewall, because the core is located inside the vehicle’s dashboard.
Does it matter which hose goes where on a heater core? – Related Questions
What happens if you put heater core hoses backwards?
You would effectively back flush your heater core temporarily. The scale and any gunk would be logged loose and now circulating in your cooling system likely to clog the radiator and possibly the core too. It also isn’t designed to be as efficient with fluid going backwards through it.
Which heater hose does the heater control valve go in?
The heater control valve is located on the top of your engine near the firewall in front of the radiator. It has two hoses attached to it; one goes into the radiator and the other goes into one side of the heater core.
Where does the engine block heater plug into?
Is the heater connected to the engine?
The heating system is connected to the engine cooling system and uses heat from the engine to warm up the vehicle. The heater core acts like a small radiator that is connected to the engine cooling system. The cooling system is filled with liquid coolant that circulates between the engine and the main vehicle radiator.
What are the hoses connected to the engine?
Your engine has two radiator hoses: an inlet hose, which takes the hot engine coolant from the engine and transports it to the radiator, and an outlet hose, which transports the engine coolant from the radiator to the engine.
Is the heater core connected to the engine?
There are two hoses connecting it with the engine – the feed pipe and return pipe. The feed pipe carries the hot coolant from the engine to the heater core. And the return pipe carries the coolant back into the engine. As the hot coolant flows into the heater coil, heat radiates from the small piping.
What are two signs that the heater core has failed?
First, the heater core could be malfunctioning and, as such, the defrosters aren’t working. Second, the core could be blowing fog/smoke into your vehicle’s cabin. Both are bad signs and need to be checked into right away.
Will you have heat if you bypass the heater core?
No you will not still have heat. The heater core uses the hot coolant from your engine and radiates it into the cabin to produce the heat you feel from your vents. Also a bad heater core is a common cause for the heat inside of the vehicle not working.
How can you tell if a heater control valve is clogged?
Below are the signs of a bad heater control valve:
No heat coming out.
Heat always on and cannot be turned down.
Heat output changes with no changes in the heat setting.
Temperature gauge reads hot.
Low coolant level.
Coolant leak.
How do I know if my heater core is clogged?
A noticeable difference in airflow could indicate that the heater core fins have been clogged and are restricting airflow.
Heater core failure symptoms
Weak or no airflow.
Cold air (not warm) coming through the vents when the heater is on.
Coolant leakage visible inside the cabin or a damp smell.
What would happen if the heater control valve was stuck closed?
If the heater control valve fails or gets stuck, it will not be able to allow hot coolant into the heater core so that the heater can operate. If the heater does not have hot coolant the AC system will not be able to blow hot air, and the front defroster may not work.
For example, failing check valves will start to vibrate and even lose some internal parts when problems begin to arise. Other symptoms of check valve failure include reverse flow and excessive component wear and damage. Check valves will also emit noises as they start to break down.

Can you manually open a check valve?
Before putting the valve into operation check the manual opening stem. For automatic operation, turn the stem counterclockwise as far as it goes; turn clockwise for manual open position.
