Where is the heater inlet hose located?

Where is the heater inlet hose located?

Both the upper and lower radiator hoses are the largest hoses in the cooling system connected to the engine. Heater hoses are smaller hoses that are attached to the heater core, which is located under the dashboard, to supply warmth to passengers in the cabin.

Does it matter which heater hose goes where?

It does not matter which way the water runs through the heater core.

Which side of heater core is Inlet?

The tubes are typically on the passenger’s side as this is usually where the heater core is located inside the dash. Step 3: Identify inlet and outlet hoses to heater core. The inlet hose may have a heater control valve which regulates the amount of coolant flowing into the heater core.

Which hose is the inlet on a radiator?

upper radiator hose
The upper radiator hose is where the hot coolant enters the radiator from the engine. It cycles through the radiator, cooling as it goes. When it reaches the bottom, it moves out of the radiator through the lower hose and back into the engine to start the cycle once more.

What happens if heater core hoses are 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.

Why is the inlet hose warmer than the heater core?

The inlet hose will be warmer as it is feeding hot coolant into the heater core which then warms the air up going into the cabin. Step 4: Make sure the engine is cold. Make sure the engine has sat for a few hours so the coolant isn’t too hot.

Where is the return line on a car heater?

Usually located inside the dashboard on the passenger side, there will be a valve controlled hose that regulates coolant going into the heater core. The other tube is the return line to get the coolant back to the cooling system. For this job, you’ll need a garden hose and running water.

Can a garden hose rupture a heater core?

Most heater cores can only handle about 10 psi of pressure whereas the typical garden hose can supply around 40 psi. Turning the flow up too high can rupture the heater core and then you’ll need to replace the whole unit. Step 2: Keep flushing until the water coming out is clear.
