Why is the outlet Hot when flushing the heater core?
Why is the outlet Hot when flushing the heater core?
The OP states he has good flow when trying to flush the core yet when the truck is operating the inlet hose is hot and the outlet is cool. That certainly points to a restricted heater core. If the heater core was plugged but the coolant was able to circulate around it without exchanging any heat then the outlet hose would still be hot.
Is there no heat after flushing a radiator?
No Heat After Flush: I Flushed My Radiator and Now I Have No Heat… I flushed my radiator and now I have no heat. While I was flushing the radiator it was blowing very hot and now that I have finished the flush and filled with coolant it blows a little warm for about five minutes and then it starts blowing cold. Please help! have the same problem?
What’s the best way to flush out a heater core?
Step 2: Remove heater core outlet hose. Slowly twist the hose back and forth while pulling to slide it off the outlet. Take care not to damage outlet port or you will have to replace the whole heater core.
Is the inlet hose to the heater core hot?
I even drianed the entire system and evacutated all the air out of the system and put a vaccum under and filled the system back up still nothing. The inlet hose to the heater core is very hot it comes out of the front of the engine but the out let hose is warm no where close to hot.

Why is the thermostat on my Chrysler 300 overheating?
If the hotter air from the condensor and radiator combined are hot enough they might get the coolant warm enough to open the incorrect thermostat, that makes some sense. Where did you get the thermostat?
What was the temp of the Ford heater?
I much preferred the heater systems of the 60s and before where the temp of the heater was controlled by a water control valve and when it was shut off NO heat entered the cabin. Why don’t you offer to buy a meal for a Ford mechanic to pick his brain. The thermostat was never mentioned.
What happens if you back flush your heater core?
If the heat in your vehicle doesn’t blow as hot as it used to, but your coolant is full, and leak free, then your heater core might be clogged. This video will show you how to back flush the heater core to clear it out and get it working again.

What to do if your 300m engine overheats?
He’s worked on 300M cooling systems before. When I turn “ON” the heat and crank the fans wide open, the temp will drop BUT not near the normal operating temp. The lower radiator hose still stays cool enough to touch. When I turn “ON’ the AC, the temp drops beautifully to normal operating temp.
Why is there no heat after a coolant flush?
Well, if you have leakage in the radiator cap, air can enter easily in the cooling system. Many times, when you flush the cooling system, gunk enters into the heater core and clogs it up. As a result, the heater core fails to provide warm air.
What are the symptoms of a plugged heater core?
If you do, the problem is with either the blend door actuator or the HVAC control module. asemaster November 11, 2017, 9:23pm #8 You have all the symptoms of a plugged heater core. Inlet and outlet temps of the heater hoses should be very close.

Why is the coolant not flowing through the heater core?
The thermostat was never mentioned. Also, the coolant may not be flowing through the heater core for reasons other than the obvious. The thermostat may be the culprit if you get half the normal amount of heat when the engine is fully hot.
What’s the name of the fifth coolant hose?
Bypass returns are generally short in length and are often considered a “fifth hose”. Although not commonplace, some engines such as this BMW V8 position their coolant bypass pipes internally in difficult-to-reach locations.
Where are the radiator and heater hoses located?
Radiator and Heater Hoses 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.
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.
Can a garden hose be used to flush a heater core?
If not, you can use a garden hose for the same purposes. Place the airline or hose in the outlet hose from the heater core. You will need to use a water hose to flush the system either way, but compressed air may move harder to break blockages. Seal the line.

Why does my hot water heater not provide warm air?
Many times, when you flush the cooling system, gunk enters into the heater core and clogs it up. As a result, the heater core fails to provide warm air. Around 50% of the time, dirt and rust are the main reasons why a heater core doesn’t provide warm air. Dirt and rust clog up the core and don’t let warm air come out.
Why is the heat not coming out of the radiator?
Well, if the heat doesn’t come out, it’s not normal. It probably means you haven’t done coolant flush correctly. At times, any foreign object or the air bubbles can be the culprit to this problem. Turns out, even foam in the radiator can cause warm air to not come out.
Why does my car heater not work when I idle?
The heater not working in some cases may be related to the overheating problem you are also having. This may be due to a faulty heater blower motor or potentially a bad heater core.
Why do I have no coolant in my heater?
If the input to the heater core is hot, but the outlet is at best luke warm, that might mean there’s no coolant flow through the core when the engine is running and the heat is set to max for some reason. Easy enough to determine by experiment. Loosen the output hose at the fire wall.
Can a bad heater core cause your car to overheat?
Can a Bad Heater Core Cause Overheating? Leaks are the #1 reason a vehicle begins to overheat. Leaks in hoses, the radiator, water pump, thermostat housing, heater core, head gasket, freeze plugs and a few other things can all lead to problems with the vehicle’s cooling system.
What to do if your car heater stops working?
Bear in mind though, that many other parts of the car could be involved in the overheating. If your heater stops putting out heat, and your engine seems warm, investigate whether there is a coolant leak elsewhere, or some other issue with your car. Overheating is very serious for your car.

Why is my hot water heater still hot after plugging in?
That certainly points to a restricted heater core. If the heater core was plugged but the coolant was able to circulate around it without exchanging any heat then the outlet hose would still be hot. There is something else going on here. As a disclaimer, I have never been a professional mechanic but mechanical systems don’t defy logic or physics.

What happens when you flush the heater core?
Allow the engine to cool completely. The coolant system is pressurized when heated, so loosening or disconnecting the heater core hoses while the engine is warm could cause it to spray hot coolant and injure you. Wait a few hours after the last time the engine was running before starting this project.
Why is my heater not working in my car?
If your vehicle’s heater isn’t working as well as it used to, or has stopped working entirely, it may be the result of a clog in your heater core. The heater core is similar to a radiator and is a part of the vehicle’s coolant system.
What to do if your heater core is clogged?
A clogged heater core will prevent the coolant from passing through it, limiting the amount of heat that can be transferred. Flushing the heater core can remove these clogs, but if it fails to work, you may need to have your heater core replaced.
