I need to change the metal line that runs from the heater core to the rear heat. I need to know how to uninstall and reinstall. Thank you

YOU CAN DO THIS TWO WAYS #1-FIND THE LEAK UNDER THE CAR AND JUST REPLACE WITH A RUBBER HOSE WHERE IT IS LEAKING, BUT LIKE ME MINE WAS SO RUST I JUST PLUG IT AT THE BEGINNING OF THE LINES ONE LINE AT THE THERMSTIC AND THE OTHER AT THE RADATER

Hi there,

This will have to be checked out by a mechanic, you will need to make sure that the cooling fans are working, there are no external leaks, the pressure cap is working and the radiator has no blockages, if that is all OK, a Co check of the cooling system will detect any exhaust gasses in the system, a sure sign of a hard or gasket problem.
