I need to bypass the heater core on a 2001 Suburban

My heater core on my wife's 2001 Suburban is out and I need to bypass it until I can get it fixed. It has two metal hoses that connect to the two rubber hoses near the firewall- do I just need to loop the two rubber hoses, or disconnect from the firewall so that all of the hoses are looped?

SOURCE: trying to bypass the heater core

The following suggestion is as old as the water cooled engine but it still works better than any solution you can buy at an auto parts store.

Total cost: $2.00

  1. Drain1.5 gallons of water from the radiator.
  2. Close the drain **** and add one gallon of boiling water.
  3. Pour in one pound of baking soda.
  4. Pour in one pint of distilled white vinegar.
  5. Replace the radiator cap immediately.
  6. Run your vehicle for fifteen minutes.
  7. Flush the radiator and fill with clean water.

If that didn't do the job, you are going to have it boiled out at your local radiator shop. The cost will be approx. $30.

SOURCE: rear heater core line leaking, can I fix w/ rubber

yeah hose and clamps are the cheap easy way to go there, or if your lucky, the leak is right at the spot where the hose meets the metal and you can just cut the end off and put it back with the old clamp

SOURCE: How do you bypass a heater core on the 2000 Chevy

Yes it can be done. look at your engine on it there will be two heater hoses coming from the engine to the heater, disconnect those two heater hoses at engine, with heater hose and two hose clamps, get the hose and clamp first at auto parts, install one end and the other end of same hose, where you disconnected the heater hoses from the engine, you have just by-pass the heater, hope this was very helpful.

SOURCE: 95 Camaro Z28 appears to be leaking antifreeze

if your rubber hoses are cracked and leaking then replace the hoses with proper size and length.
if the hoses are leaking where they connect to the metal fittings from the heater core then try and tighten up the hose clamps -- they could just be loose.

Heater blows cold air--where is heater control flap or switch?


These cars are notorious for having blocked heater cores, causing the heater to blow cold air. That's because there is a heater core bypass hose near the firewall that allows the coolant to bypass the heater core. Eventually the heater core fills with gunk and no coolant passes through it. You'll need to disconnect the hoses from the heater core at the firewall and flush the core using a garden hose. Flush both ways till water runs clear. If you can't access the heater core fittings at the firewall, then follow the hoses from these fittings back to the engine and disconnect them at that point and flush from there. If you flush from the hoses in this manner, it is important that you clamp off the bypass hose at the firewall with a vice grip pliers.
Otherwise the flushing water will go through the bypass hose and not the heater core.

Heater is not getting hot enough


This is a very common problem on the Taurus, at least up until the 2001 model and possibly later. The Taurus design incorporates a bypass hose (near the firewall) that connects between the heater hoses entering and exiting the firewall in the engine compartment. As the Taurus ages (6 or 7 years old), the heater core under the dash increasingly gets clogged with gunk because the bypass hose provides a path for the coolant to bypass the heater core itself. The fix is to disconnect the heater hoses at the engine block (too difficult to disconnect these hoses at the firewall-no space) and flush the heater core through these hoses with a garden hose. Before doing this you must crimp (with vise grips and a rag to protect the rubber hose) the bypass hose--otherwise the flushing water will bypass the heater core. I attached the garden hose to an adapter that I could clamp into the heater hose to make the connection. BTW, the coolant in the radiator was a pristine lime green color -notice the dark brown color of the gunk flushed from the heater core. b4d9b81a-db6d-4a32-852d-2725671d69af.jpg d06ea83d-50ae-4178-a917-1275133ccd9c.jpg c195fd24-d013-4f9c-a878-5e49e1ff2612.jpg 2d1a9536-3c83-45c8-8d60-7eea7e95a4e8.jpg 1cc41e46-c4dc-4f8f-924c-4c751e5051f8.jpg

I have a 2001 Legacy twin turb Gtb Wagon, When im driving i can smell an oily smell coming through the Air conditioning. the Smell is actually quite similar to burning coolent. whats the guts with that?


Hi and welcome to FixYa, I am Kelly. You have a leaking heater coil. Check your radiator coolant levels and I am certain that over several days you will note your car is suddenly using water. That sweet oily smell is anti-freeze. Many people bypass the heater coil lines in the engine compartment until they can get the heater core replaced.

Bypassing the heater core is done by disconnecting the lines forward of the firewall in using a pipe nipple or piece of copper tubing with clamps. I recommend you either bypass the lines or have the heater core replaced ASAP. You run the risk of overheating your engine from coolant loss.
Thanks for choosing FixYa.

Replace the heater core


If you don't live in a place where you need the heat, you can bypass the heater core all together. Take both hoses loose from the heater core, which should be located to the left of your evaporator (the black box that mounts to the firewall and connects to your a/c accumulator. (the aluminum thing) by taking two hose clamps and a spark plug socket, you can combine the two lines together, which bypasses the heater core. I would recommend shortening the line coming from the radiator before connecting. The spark plug socket will serve as a connector or modifier to go between the smaller line and the larger.

the heater bypass is quite simple, if you look at the firewall you will see two medium sized coolant lines, remove them from the firewall and link them together using a proper sized tube, you can purchase a kit at a parts store quite cheaply
