Most definitely. The hose you are referring to is most likely the drain designed to expel condensation from the A/C which is housed in the same box.
the heater core could be pluged or the heater control valve is stuck closed
could be a cracked radiator, bad radiator cap, a busted radiator or heater hose, bad heater core, or a busted fill box!
Its more than likely your heater core.
Check the thermostat or the radiator. The thermostat could be sticking or the radiator could be plugged.
its the heater core. but its not clogged. its cracked
You have to be more specific. What is not working?
Radiator fluid or antifreeze as it's called circulates through your heater core under the dash and provides you with heat and warm air for defrost. If you are smelling it inside the car then your heater core may have a leak. IS there any visible signs of leakage on the carpet in the car? The heater core usually has an inlet tube and an outlet tube through the firewall and maybe one of these is leaking. It could be leaking on the outside as well. Look for wetness around any hoses connecting to any tubes coming through the firewall. If you keep having to add antifreeze, you definitely have a leak.
Could be: Low coolant in the radiator - or - thermostat stuck open - or - heater core plugged.
Your car could be low on antifreeze or your heater core could be clogged. With my car, it was Heater matrix clogged with radiator sealant. The workshop cleaned it and it's start working fine!
I wouldn't think you could flush a heater core. you can flush a radiator. Heater core you would have to replace if it is leaking or stopped up
Could be the heater. It's likely that most of the hoses to the rad were changed, but maybe a hose to a heater (if you have more than one), or the heater itself.
heater hoses. or could be the run off water from your A/C unit
Theres a leak. Probably a hose but could be radiator or heater core, water pump or engine core plug
well you could just turn the heater off heater blower ---- If it is a car heater then check your coolant level. the heater is driven off a heat converter that is fed by the radiator system. When the coolant fails to pump round the radiator system the car internal heater doesn't work. Driving without coolant in the system will result in the engine overheating and seizing.
Only if it is allowing Fluid to escape. Does the radiator and heater core have enough fluid to circulate. If not you will not have heat.
The heater core could be bad. Or, as was my case, you may have issues with your radiator. If the radiator is cracked and is not able to generate enough pressure the heating system will not function.
It could be the heater valve which is located under the hood to the passenger side down below the radiator and fan units.
try switching the 2 heater hoses around, they may be backwards
Most radiator pet cocks are located on the bottom left (drivers) side of the radiator and be warned they have a left hand thread. Some of the newer models I have seen do not have one but could be drained by loosening the lower hose.
If you are getting no heater fan inside, then probably the heater blower motor resistor or fan motor. If the fan blows and you get cold air, then check the coolant level in the radiator first. If coolant level is good, then check to make sure the heater control head in the vehicle is actually on heat position, with regards to the heat door down below under/behind dash. Sometimes the actuator door/heat blend door get's stuck or broken in one position. Also could be a stuck thermostat or clogged heater core. If a clogged heater core, could try switching hoses at firewall to unclog.
Could be a bad heater core...also, could be low coolant level. With my car, it was Heater matrix clogged with radiator sealant. The workshop cleaned it and it's start working fine!
Could be because the coolant level is too low. With my car, it was Heater matrix clogged with radiator sealant. The workshop cleaned it and it's start working fine!
If you are leaking coolant and there isn't enough to circulate into the heater core, perhaps the radiator cap could be partially responsible. Otherwise I'd suspect the thermostat, the heater valve or the water pump. But then, if it's the water pump the engine would probably be overheating.
You could try, but it will be a temporary fix at best and could plug up the heater core or radiator at the worst.
Your radiator may be running low on fluid. Failed thermostat, damaged heater valve, blocked heater core/heater hose or worn out water pump. it could be a couple of things like the themostat or the heater core .
