If your radiator heater is not working properly, you should first check if it is receiving power and if the thermostat is set correctly. If those are not the issues, you may need to bleed the radiator to release trapped air or check for any leaks in the system. If the problem persists, it is recommended to contact a professional HVAC technician for further assistance.
If you have replaced the water pump then flush the radiator with CLR also check to see if the fan is working properly.
If your apartment water heater is not working properly, you should contact your landlord or property manager immediately to report the issue. They are responsible for ensuring that the water heater is in good working condition and should arrange for a professional to repair or replace it as needed. Avoid attempting to fix the water heater yourself, as this could be dangerous and may void any warranties or rental agreements.
If your water heater is not working properly, you should first check the pilot light and thermostat to see if they are functioning correctly. If they are, you may need to flush the tank to remove any sediment buildup. If these steps do not fix the issue, it is best to contact a professional plumber to assess and repair the water heater.
The heater core is basically a small radiator located inside your car. If your "real" radiator isn't working quite as it should, then the heater can carry some of that load. Then if you turn the heater off the engine will run hot when it's only got the bad radiator left to cool it.
If you are absolutely, positively sure that your coolant level is not low......then your heater core could be plugged. Or the control that turns the coolant flow on/off to the heater isn't working. Make sure the control is working, the flush the radiator. Should cure the problem.
When your car is at idle there is no air flow to cool the radiator, but when your car moves the air flow through the radiator cools it down. I would suspect the radiator fan is not coming on when it should. If the fan is working properly the engine temperature should stay fairly constant assuming the thermostat is also working properly.
If your water heater isn't working properly, first check the pilot light and thermostat. If those are fine, consider checking for any leaks or sediment buildup. If you're unable to fix it yourself, contact a professional plumber for assistance.
If your heater core wasn't leaking at the time your radiator was replaced , then ( no ) That would be two separate jobs
The AC switch operates the AC compressor and should have no bearing on your heater function. If your heater is not working properly, you may have a weak thermostat.
Not hard. Take the radiator cap off and crank it up and let it run until it gets to operating temp. You should be able to see the coolant moving inside the radiator. if it is, it's working.
It will take a little longer for the cooling system thermostat to open up if the heater fan is on. The heater fan and heater core act like a small radiator and disperses heat energy when in operation.
Sounds like the heater core is plugged. Have a competent garage flush the radiator and heater core, then refill with fresh coolant. Should cure the problem.
