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

These are on of the hardest heater cores in the industry to replace. A typical garage will get between $800.00 and $1200.00 to replace, the dealer will get $1600.00 because you have to completely remove the steering column the dash, discharge the A/C system reomve the heater box, split it and replace the core. The job is so labor intensive you would be crazy not to replace the A/C evaporator at the same time. This is not a job for an amature or ever a class "B" tech. leave this one to the Pro's.

SOURCE: bad heater core on my 2001 lincoln navigator

This is definitely not a job for the at home mechanic. the dash will probably have to come out and this is a very time consuming and laborious task. I would recommend you find a job that you can trust, or get several estimates on the work before you decide who to let do the work. I would expect something like this to run at least $700.00 to $1000.00

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.

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

Under the hood is a drain for the cowling under the wiper arms. There is a plastic tube that gets clogged and water can't drain from that area. It is against the firewall on the passenger side. I found mine full of pine needles

Hey, radiator fluid is leaking from the back left of my navigator


What happen is there is a return and a supply to your heater core, but there are two heater cores a front and a back if you look underneath the truck you will see lines going to a core out back. I dont believe there are relief opening back there, but maybe a drain. most likely the lines going to it need to be replaced. good luck
