Can a radiator get stuck in a heater core?
The heater core looks a lot like the radiator in miniature scale. In fact, the inside of the heater core has a similar network of small gauge tubing, which works to produce hot air for the heating system. If scales or debris break away from the radiator piping, it could end up stuck in the small tubing of the heater core.
Can You reverse the flow through the heater core?
Removal of hoses confirms that there is very limited flow through the heater core. I flushed it but got only minimal improvement. However when I back flush (reversing the flow through the core) the flow is great. Here’s the question: Can I reverse the flow through the heater core on a permanent basis?
What happens if you flush the heater core?
What happens if you flush the trash clogging the heater core back into the block? 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… but that will not prevent it from carrying crud from the core into the engine cooling system.
How can I stop coolant from running out of my heater?
if your replacing the rubber hose part remove the clamps and pry out the hose,coolant will run out from the lines just plug them with a rag or paper towel.If your replacing the metal lines disconnect the hose from both hose sides and the bracket that holds it to the firewall. Loading…
Where are the hoses in a jeep heater?
68137715AA is the whole supply and return hose/tube assembly (for 2011 5.7 engine, possibly different part if you’ve got something else). The assembly includes two small hoses that lead from the firewall to and from the core.
Do you need to replace heater core fittings?
To answer your question directly, no, you do not need to disturb the dash to replace anything that you can see from the engine side. If it’s just leaking from a hairline crack in the black plastic elbow you can swap that out. It’s tight and awkward but definitely doable.
Where are the return hoses on a jeep?
It looks like the heater core supply and return hoses connect with spring clamps on the back side of a mounting plate that sits flush with the firewall. This plate appears to be secured to the firwall with small screw in the bottom left corner (as viewed from the engine side).
Where are the heater core fittings in a GC?
It connects to the heater tubes coming from the heater core and goes through the firewall. It includes the hoses and quick connect fittings that you’ll see in the engine bay too. I’d post the part number for others but there are three possibilities for 2011 GC.
What happens when the radiator thermostat is stuck?
You can tell the thermostat is stuck closed by carefully touching the radiator hoses. The top one will feel hot, yet the bottom hose will remain cold. When the thermostat sticks open, the engine will never reach operating temperature, which negatively impacts gas mileage.
How can I tell if my thermostat is stuck?
When the thermostat fails, the valve inside gets stuck either open or closed. With a closed thermostat, your engine will immediately start to overheat. You can tell the thermostat is stuck closed by carefully touching the radiator hoses. The top one will feel hot, yet the bottom hose will remain cold.
Where is the thermostat located on a car?
To control the temperature, the thermostat sits at the end of the top radiator hose, keeping coolant in the engine block until it is needed to cool the radiator, before being pumped out through the bottom radiator hose. When the engine reaches ideal operating temperature, the thermostat opens and allows the cooling system to flow freely.

What happens when the radiator in a house goes bad?
The three parts that commonly cease working after the radiator goes bad are the thermostat, water pump, and heater core. Here is a breakdown of what each of these parts does and what happens when they fail.
