If your heater core wasn't leaking at the time your radiator was replaced , then ( no )

That would be two separate jobs

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.

The radiator drain plug should be close to the bottom of the radiator facing the engine. It could be a wing nut, or could be the type that is turned by a ratchet and extension.

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.

The thermostat on a 1992 LeSabre should be inside of the top radiator hose inlet. You can easily change it by removing the top hose and water inlet.

Replacing the heater core on this application is of moderate difficulty. The first steps are disconnecting the under-hood heater hoses and disassembling the glove compartment area to access the core radiator. These can be removed and reinstalled with simple tools. Once completed upper and lower radiator hoses should be inspected and replaced as needed. The OEM replacement heater core for Buick Skylarks with the 3.3L V6 is AC Delco #1563718. The vehicle may also need the heater core seal replaced at the same time. It is advisable that the system be flushed and charged with fresh coolant as part of this service. Finally the system should be pressure tested, and also the heating system turned on to verify operation and check for leaks.

It could be that you are low on coolant, but if that is not the case, your thermostat may be stuck open. After the vehicle has been running for about 15 minutes, put your hand on the top of the radiator. If it is not too hot to touch, your thermostat should probably be replaced.

i think you might be talking about the heater hoses , if so it might be the heater control valve . the is a upper and lower radiator hose , but nothing should be between them.

You have to remove the upper headers and it should be there toward the radiator and the fuel rail

The old Honda Civics didn't come with the block heater. It's an option or aftermarket...If your car is equipped with a block heater, it should be located in front or at the side of the radiator......

Locate hoses under hood that go to the heater core. there should be 2. They are rubber hoses, smaller than the radiator hoses. after you have located them, leave hood open, start the car. Feel the hoses as the car warms up, one hose is an inlet to the heater core, one hose is an outlet. if one hose gets hot and the other does not, then the heater core is restricted, and may need replaced or flushed.

well the Honda civic has main problems with the thermostat and radiator considering the year if it has never been replaced you should replace the thermostat then radiator cap and if this doesn't help you can do a pressure test to see if you have a leak or blown head gasket. the car could also have a bad water pump if this is the problem it will only take Min's to over heat the engine. you could havethings blocking your radiator i would have this flushed or replaced. also it could be your heater core hope this helps

Have you replaced the thermostat? The water in radiator should not be boiling! ------------------------------------------------------------------------------------------------------ Is your cooling fan/viscous clutch working ? (Helpfull)
