Heater core metal line to rear heat

I couldn't find a heater hose diagram specific to the 1999 Chevrolet Venture with rear heat and air, but I can give you the general location of the heater hoses and how to identify which ones go to the rear heat. The heater hoses on a 1999 Chevy Venture are located on the passenger side of the engine compartment. There are two heater hoses, one that is hot and one that is cold. The hot heater hose will be connected to the heater core, which is located under the dashboard. The cold heater hose will be connected to the engine. To identify which heater hose goes to the rear heat, you can look for the hose that is connected to the heater core outlet that is labeled "Rear Heat." The other heater hose will be connected to the heater core outlet that is labeled "Heating Core Inlet." Once you have identified the heater hoses that go to the rear heat, you can reconnect them to the heater core. Be sure to use new clamps when you reconnect the hoses. Here are the steps on how to replace the heater hoses on a 1999 Chevy Venture with rear heat and air: Disconnect the negative battery cable. Drain the coolant from the radiator. Remove the heater hoses from the engine and heater core. Install the new heater hoses. Fill the cooling system with coolant. Reconnect the battery cable. Start the engine and check for leaks.

The heater hoses run to the backside of the motor and connect to the heater core on more towards the drivers side of the firewall. If you have rear heat there will be two metal lines that run under the vehicle on the passenger side. Those lines will connect to two rubber hoses that are attached to the rear heater lines that make there way to the rear heater core and connect just in front of the passenger rear tire.

i am assuming you mean heater core, you have to remove the pass rear cargo trim panel and any trim that interlocks to it as well as any connectors then the heater box and hoses from under the vehicle as well as if it has rear ac the ac system needs to be discharged first and those lines removed as well, then remove the box from the vehicle and seperate the case halves and replace the core, the reinstall in the reverse order of removal

IT WORKS LIKE A LOOP YOUR HEATER CORE ACTS LIKE A U-TURN SO IF GET A U-SHAPE PIPE AND CUT THE HOSE TO FIT IT WILL SOLVE YOUR PROBLEM

Hi Lerverne,here' a link on your rear heater core. Repair Guides Auxiliary Heating Air Conditioning Heater Core AutoZone com Here's a link to a new rear heater core. Spectra Premium Heater Core

A call to the dealership should be able to get you the official name but I would desribe them as the rear heater core lines. These lines basically supply heated engine coolant for the rear heat. A dealership parts dept can pull up a diagram of the vehicle based on the VIN number and give you the exact name and part number.

Hi, this is the heater core for your rear heater. If it's leaking from inside the box, it's likely the core is bad. Please let me know if you would like instructions for replacing the rear heater core. A new core is $92 at autozone, but I would shop around. Make sure you specify the rear or auxiliary when ordering a new new core, as the front core is different.

If the tubes going to the rear heater core are the problem , drain the system and replace the bad tube/tubes. If the actual heater core is leaking and you do not want to go to the expense of replacing it, unhook both tubes at the back of the motor , cut out a good section of hose and use it to loop/connect the outlet line and inlet line on the motor side (not the rear heater core side). This will bypass the rear heater core , the front heater core should be adequate to heat the whole car. If you have a pin hole in a section of solid (copper) tubing, you can cut out the bad section and reconnect it with some heater tube and two hose clamps.

Not sure what information you need, but before you spend a lot of time call the dealer and give them your vin number. It does not matter how many owners, but there was a recall on those lines around that time. If yours is one of them they will replace the whole set of heater and air conditioner at no charge to you.

Have you thought of sandpapering the lines clean, then using JB Weld?
