Which hose is the inlet to the heater core? (video)


Where do heater hoses connect? (video)


Which radiator hose is the return?

In most applications, the return radiator hose is the lower or bottom hose on the radiator. Coolant is sucked out of the radiator by the water pump through this hose and it enters the engine block. via

What hoses are connected to the radiator?

There are two hoses that connect to the radiator. The upper hose attaches from the top of the radiator to the top of the engine. The lower hose attaches to the bottom of the radiator to the water pump of the engine. via

Which hose is the inlet?

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. via

What happens if you hook up heater core hoses backwards?

By reversing the hoses, the coolant will flow in reverse direction through the core, but it'll still be flowing in the same direction as far as the engine is concerned. This may not prevent it from carrying debris from the core into the engine cooling system. via

What does the lower radiator hose connect to?

The radiator hose transfers coolant from an engine's water pump to the radiator. An upper hose connects the top of the radiator to the top of the engine. A lower hose connects the bottom of the radiator to the water pump, which keeps coolant flowing through the system. via

What hoses are connected to the engine?


  • Fuel hose (sends gasoline from the gas tank to the engine)
  • Radiator hose (delivers coolant to engine)
  • Power steering hose (connects power steering pump to steering equipment)
  • Heater hose (provides coolant to heater core)
  • via

    Do heater hoses have coolant?

    One heater hose carries hot coolant from your engine into the heater core. Air from either inside or outside the vehicle then passes through the hot heater core, which warms the air before it enters the passenger compartment of your vehicle. via

    What are the 2 different types of radiator hoses?

    There are two types of radiator hoses, upper and lower. via

    Does it matter which way water flows through a radiator?

    water flow: no difference. air flow: left<->right no difference. up<->down heat rises so most people go up. via

    Which radiator hose should be hot?

    One way to check for proper coolant circulation is to check the upper and lower radiator hoses. The upper radiator hose should be hot, around 190–200 °F. (The safest and most accurate way to get this temperature reading is with an infrared thermometer.) via

    Which way does coolant flow through heater core?

    The hose on the right (passenger) side comes from the top of the head, HOT water. The left side returns cooled water from the radiator to the thermostat to the water pump and then into the engine block. via

    What are the different hoses?

    Types of Hoses

  • Chemical Transfer Hoses.
  • Working with chemicals can be very dangerous, so your hose must withstand the pressures you are putting upon it.
  • Petroleum Transfer Hoses.
  • Steam Hoses.
  • Food & Beverage Hoses.
  • Abrasive Material Hoses.
  • Air Hoses.
  • Water Hoses.
  • via

    Are heater cores directional?

    The core will heat up no matter which direction. However, some heater control valves are directional, usually they have an arrow on them to indicate direction, and will function better if installed correctly. via

    How do I replace the bottom radiator hose?

  • Open the hood and locate the vehicle's radiator.
  • Place a drain pan under the radiator.
  • Remove the lower radiator hose from the engine.
  • Place the clamps over the hose ends.
  • Refill radiator with a 50/50 mix of the recommended type of antifreeze and water.
  • Leave the radiator cap off and start engine.
  • via

    What is connected to the bottom of the radiator?

    The lower radiator hose connects the bottom of the radiator to the water pump, which pumps the coolant throughout the system. Both hoses are connected to their ports with hose clamps. via

    Does the bottom radiator hose have pressure on it?

    The lower radiator hose is primarily a suction hose. The water pump, as it spins, draws coolant from the radiator into the engine. This creates an area of low pressure at the bottom of the radiator, which can cause an ordinary hose to collapse. via

    How much does it cost to replace heater hose?

    When heater hoses need to be replaced, the average cost is between $150 and $250, but may be more depending on the make and model. Because coolant constantly circulates through the heater hoses, it doesn't matter whether you use the heat or not – they deteriorate just the same. via

    What forces the coolant to flow throughout the engine?

    Coolant follows a circulation path that begins with the water pump. The water pump's impeller uses centrifugal force to draw coolant from the radiator and push it into the engine block. Pumps are usually fan, serpentine timing belt, or timing chain driven. Nowadays, they may even be driven electrically. via

    How many coolant hoses are there?

    In a typical automotive cooling system, you'll find at least 4 main hoses. First, the upper radiator hose leads directly from the thermostat housing (on the intake manifold or cylinder head) into the top of the radiator. Attached to the bottom of the radiator is a lower radiator hose. via

    Can you drive with a leaking heater hose?

    Not curing the issue and continue to drive the vehicle this way can lead to further engine damage. Damage in an engine can also be a result of a leaky hose, radiator, head gasket, water pump, and several other tools other than the heart core. via

    What is the difference between a heater hose and a coolant hose?

    Coolant hoses and heater hoses are essentially the same thing, but applied towards different purposes. Coolant fluid, like Freon, is much more effective at cooling an engine (and heating a car) than regular water, because water boils and freezes much faster than Freon. via

    Do I need to drain coolant to replace heater hose? (video)


    What does a radiator hose look like? (video)


    Can you drive with broken radiator hose?

    Do not drive with leaking coolant. Overheating engine: Since the radiator cools the engine, a cracked radiator may not cool the engine like it is supposed to. This can cause the engine heat to rise, and eventually the vehicle will overheat. via

    How do you fix a leaky radiator hose? (video)


    How do you tell which is the flow and return on a radiator? (video)


    Which side of the radiator is the inlet?

    Discovering where the valve inlets on your radiator are is fairly straight-forward and is defined primarily by the kind of radiator or heated towel rail that you have. With a heated towel rail, for example, you will normally find that the inlet position is located underneath at the bottom. via

    Can a radiator flow both ways?

    Can Radiators Flow Both Ways? You can use two-way thermostatic valve if your radiator is flow pipeed – so you won't need to wear two different hoses. Keeping your radiator flowing in the right direction is always best to fit the TRV on the inlet pipe. via

    Which is hotter upper or lower radiator hose?

    The heat from the engine can cause the top radiator hose to get hotter than the bottom one. So why is this? The answer has to do with how radiators work. via

    Why is the top radiator hose hot and the bottom one cold?

    During its time flowing through the radiator, the coolant will transfer most of its heat to the outside air. But not all of it. So the lower hose will also get warm but not nearly as hot as the upper hose. via

    Are both heater core hoses supposed to be hot?

    To properly warm the interior of your vehicle, then both heater hoses should be hot. If one is noticeably hotter than the other, then there could be a clog in the hose. In addition, if the heater hoses are cold, this is also a sign of clogged hoses. via

    Does coolant flow through heater core when thermostat is closed?

    The thermostat is located between the engine and the radiator. This little temperature-sensitive spring valve stays closed during engine warm-up. When the thermostat is closed, it prevents coolant from leaving the engine and circulating through the radiator until the correct running temperature is reached. via

    Is it OK to bypass the heater core?

    You basically take the two hoses off the heater core, you stick them together and you're done. That way, the coolant will continue to circulate, even though it no longer goes through the heater core. And bypassing the heater core should have no effect at all on the performance of the engine, Charles. via

    Which of the following system parts controls coolant flow through a radiator?

    Thermostat. The thermostat is simply a valve that measures the temperature of the coolant and, if it is hot enough, opens to allow the coolant to flow through the radiator. via

    How many types of hoses are there?

    Hoses are divided into two categories, based on their use: suction hose, and delivery hose. After use, a fire hose is usually hung to dry, because standing water that remains in a hose for a long time can deteriorate the material and render it unreliable or unusable. via

    What is unlined hose?

    Hose commonly of cotton, linen, or synthetic fiber construction without rubber tube or lining, often used for wildfires because of its light weight and self protecting (weeping) characteristics; such hose is attached to first-aid standpipes in buildings. via

    What is hose pipe and type?

    RRL Type A Hose pipe

    rrl-type-a-hoe-pipe Reinforced Rubber Lined Hose is preferred by the fire fighters due to their excellent durability. The jacket is made of 100% synthetic yarn. RRL Hose has excellent heat and abrasion resistance. This hose meets the requirements of IS 363 – Type A. Material. via
