You would actually install a valve to cut off the flow through the heater hose. If you just "unplugged" the hose, you'd spit out antifreeze everywhere. The purpose is to cut off hot engine coolant to the heater core. In the Summer months, you might get a couple degrees cooler air out of your AC system doing this. If you have a vehicle which uses a heater control valve, and that goes faulty, this is often what you'd have to do in order to get the AC to work. Barring that, you could pinch the heater hoses off with a set of hose clamps (preferable) or needle nose vice grips, tie them up real good with wire ties to ensure they don't come off and drop into the engine compartment, and run that way in lieu of installing the valve.
Start the car, turn the heater/blower on full, The hose that is the hottest is the Inlet. The coolest is the Outlet.
a heater hose runs from intake to heater core to radiator. the heater core is were the heat comes from inside the car as well as defrost
There is a small black hose sticking out from the passengers fire wall and has been leaking out water over the last couple of days from having the heater on inside the car. The hose is under the passenger side part of the car up by the fire wall or heater core area. Is this normal for this car? Is it a cool off or overflow hose?
It connects to a heater hose behind the engine.
Kinda-sorta. Most cars, the heater is part of the cooling system. If you pull the heater hose off you're left with a hole that'll drain the coolant out. If for some reason you want to run a car w/o the heater hose or the heater, you need to make sure that the coolant still can circulate as it's expected. You'll either need to plug something, or run a bypass loop.
A vehicle block heater's main purpose is to warm an engine enough to increase the car's starting speed. This is especially useful in winter to get a car started.
under the dash board you will see two hose let the car warm up and feel the hose if both are hot then its not ur heater core...but if 1 is hot and the 2nd is not then you need a heater core :-]
A heater hose or heater core is in need of repair. stonemkr reverse painting on glass
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.
I just had a radiator put in my 2000 Honda accord Friday today the car over heated I had it towed back to the shop that did the work they charged me for a heater hose and the tow
On a 1989 Chevy Celebrity the heater hose leaves the water pump via a hose barb then runs along the top of the passenger side frame rail and then into the heater core. The heater core is in the firewall below the blower fan on the passenger side of the car. The return hose leaves the heater core and runs along the firewall then to the water outlet below the thermostat.
Called a Heater Core in North America. This is a little radiator to make the air in the car warm
