Anyone have any images/videos on how to do a heater core bypass? Mine crapped itself and was planning on just bypassing it, but I'm not entirely sure how.

 

go from upper heater hose to lower hose in a loop ,water pump to intake ,,make it about 1-1.5' long so no kinks

and flush out the heater core with hot water,and let it drain

 

Does your car have ac? Putting in a new heater core is a 10 min job tops if it desn't have ac.....

 

Factory AC car. Weren't for that, I'd've already replaced it and not chosen to bypass.

 

Try Dorman Products, using Google maybe. Black plastic fitting, with hose barbs, one end is 5/8, the other end is 3/4. Remove your hoses from the core, install by-pass fitting, clamp it, be done with it.

 

i have the fitting, how would I install it? Like disconnect the hoses, put it in place of where the hose went and then?
Sorry, I’m better with things OTHER than hoses alas

 

I've since changed it out to have a 3/4" fitting on the intake manifold, so I have a single 3/4" hose now (with an internal restriction), but here is the only photo I have with the Dorman 5/8" to 3/4" joining the two stubs of hose. Outlet (5/8") comes from intake manifold, 3/4" hose goes to the long tube on the water pump. If it isn't obvious, you will have to cut both hoses.

 

One of the BEST tools all Vette owners should have and it does not fit in a tool box, is a set of ramps. Get that thing up in the air and you will see how easy it is the remove the clamps / heater hoses off of the core. Then just hook the hoses to the by-pass gadget and clamp. Leave it at the bottom of the firewall.

 

Okay, how about this, I want to bypass the heater core but I still want the appearence of the hoses running to the heater core. The only thing I could come up with is a solid hose bib that looks stock but is welded closed. Thoughts................................ ................

You are hi-jacking someones thread. How do we know who we are answering, you or the O.P?

 

This is the bypass I did some years ago. After some months i took courage and i've replaced theheater core.

 

Thank you all! These are exactly the kind of photos I was looking for.

 

Just get two plugs it's the easiest and cleanest way to do it take out the old nipples and get plugs at the auto parts store.

 

I just added a shut-off valve to the hose inlet to the heater core (from the water pump).
I used a lever ball-**** brass valve from the plumbing aisle at H.D., the kind with barbed hose fittings, and used stout clamps on both sides.
My goal was not to permanently bypass the heater, but just be able to shut it down during the hot summer months. (my problem is somewhere in the mode door area, where I can't get the hot air flow to stop, even with fan off and the mode set to OFF).
This gives me the ability to turn it back on in the cooler driving months.
To do this, you need to make sure you've got good radiator performance currently, since the system may rely on the help of the heater core to disperse heat in the event of an over-heating condition.
Shutting off the flow between the water pump and the heater core won't affect the engine cooling and water flow under normal conditions, as you're just bypassing that loop.
I also make sure I open it up each season to make sure I don't have stagnant fluid in the core long enough to promote corrosion.
I don't have any photos currently, but I did place the valve down low and close to the firewall for low visibility.
My only regret was not using the turn-**** style of valve, as the lever type is a little more obvious, and has a hint of "Bubba" to it!!

 

My C3 is still hot inside with heater delete LOL.

 

Got the bypass done

 

Not quite, you have to post a picture to help the next person with the same question.

 

Totally unnecessary. Two pipe plugs work fine, and leave a cleaner looking result.

 

Now you just have to pay your bill.

Statement code # M4A3E2.
Heater Core By-Pass issue.
Result: Resolved.

That will be $119.
How do you wish to make your payment?

 

Well, when he gets his core fixed the hoses will be right there, ready to go.
