Which is the inlet and outlet on the heater core?
If I’m in front of the car facing the firewall which nipple on the heater core is the inlet and outlet, would like to flush out heater core , but before I hook up hoses I don’t want to flush it on the inlet side , don’t want to compact more stuff into core, want to back flush it first a few times right hose: inlet. left hose: outlet.
How are Inlet and outlet lines drawn on a heat exchanger?
Inlet and outlet lines are the next to be drawn up. Line number, material class, size etc. is to be correctly assigned to each of the lines. If the unit is envisaged to be in operation while the exchanger is under maintenance, then bypass lines should be drawn up on shellside, tubeside or on both sides as shown in the drawing presented here.
Why is my water heater supply line hot?
Also copper piping is a good conductor of heat. Many modern water heaters have built-in heat traps to limit the migration of hot water. However, hot water five feet back on the supply line is not normal.
How to draw a heat exchanger P & ID diagram?
This should be selected from the list of equipment symbols on the legend sheets of a particular project. All the nozzles on the exchanger should then be correctly represented with size and flanges. This includes inlet and outlet nozzles, drains, vents, utility connections etc. Inlet and outlet lines are the next to be drawn up.
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.
Is there a way to connect the thermostat to the heater?
Yes, there is no way that connecting the two top hoses of the thermostat housing to the heater will do any good. The thermostat housing has two outlets one inlet (apart from the radiator hose) Two +ve outlets horizontally opposed at the top and a return/inlet at the bottom.
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.

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 does the coolant go after flushing out the heater core?
The inlet hose may have a heater control valve which regulates the amount of coolant flowing into the heater core. The outlet hose will typically run straight to the radiator or cooling system reservoir to return the coolant after flowing through the heater core.
What should I do if my heater core comes out?
Take care not to damage outlet port or you will have to replace the whole heater core. If the hose is old and caked onto the outlet port, you may have to replace the hose as removing it will likely damage the seal. Liquid will most likely come out as well so have the rags ready to clean up any spilled coolant. Step 3: Attach garden hose to outlet.
How can I check the temperature of my a / C heater?
Check the temperature-control flap-door operation in the under-dash heater-a/c case. Dangle the thermostat in hot water while you monitor the temperature. The ‘stat will drop off as the water rises above the ‘stat’s actual (rather than rated) actuation temp.
How can I tell if my car heater is working?
Make sure there’s strong airflow from the floor registers. Check the temperature with a thermometer inserted into the driver’s and passenger’s registers. Although many vehicles deliver a toasty 135° to 155°, 115° to 120° is acceptable. If the air temperature is okay but airflow is weak, the problem is the blower or a dashboard ductwork problem.
What’s the best way to turn up your heater?
Replace the cap. Top up the system and purge air, following the vehicle maker’s specific procedure. As a generic approach, start with the engine cold, all bleed valves open, and the side of the vehicle with the coolant neck jacked up as high as possible. This raises the fill neck to the high point, so air bubbles out.
How much pressure can you put on a heater core?
Step 1: Turn on the water. Don’t turn the water on all the way; usually a quarter to half of a turn from fully closed is enough. Most heater cores can only handle about 10 psi of pressure whereas the typical garden hose can supply around 40 psi.

Where is the hose on a car heater?
Carefully examine the hose from the water pump back to the heater core inlet and outlet near the firewall (backside of the engine compartment). The leak may be at a fitting on the water pump or even at the heater core.
What causes the radiator hose to come out of the car?
This alone doesn’t mean you have a blown hose, however. It could be a faulty thermostat that caused the radiator cap to release. If the cap has a pressure-release flap that’s released, your engine may have only overheated, but if the cap is intact and you can see a leak in the heater hose, you’ll be able to fix it.
What should I do if my radiator hose breaks?
When one connector breaks, the other is usually not far behind. You should replace both connectors at once to avoid a repeat situation. One of the hoses has a plastic Y on it, one hose goes to the heater core, one comes from the radiator overflow canister, and the other side goes to the water pump.
