Heater hose diagrams

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.

All depends on what you are working on, but it is usually the one from the pump.

Go to TASCA Ford parts and they'll have a diagram of the hoses,probably. Also a place called Ford Parts Giant. don-ohio

Most likely while you are in there it's time to replace the hose. Saves having to go back if it starts leaking on the other end which is highly likely given the age. There should be a return heater hose, it is probably in similar condition. Diagram may be available via google. Youtube may show you how to. A very bright led flash light will allow you to see and trace the heater hose. You'll need to drain the radiator save the antifreze if new. Replace if old. Any other cooling system hoses need to be replaced? How is the water pump. It's not the leak is it? Otherwise Library probably has repair manual, or may be time to invest in repair manual. Lightly used may be available on Ebay and others. New hoses are cheap insurance against possible failure.

Your car is overheating because you did not bleed the cooling system. The hanging hose may be the overflow drain. Unbolt the coolant reservoir, and raise it as high as you can. Start the motor, and add coolant until the heater starts blowing heat. You will see air bubbles in the reservoir until all of the air is out. This is a common procedure when doing any cooling system maintenance on Celicas.
