Heater Bypass Valve Removal Pics
I posted this in the cooling section too...
Can a few people post some pictures of their heater hoses after they took out the heater valve, or coolant bypass valve, or whatever its called. Thanks guys!

Re: Heater Bypass Valve Removal Pics
Really confuses everyone - please pick ONE section and post only once there - wastes our time reading same posts all day, wastes your time having to look in 3-4 places to find the answer for one question!

Re: Heater Bypass Valve Removal Pics
I appreciate your help, but because i wasnt having any luck getting a response for my original post, and have seen this discussed in many sections, i tried widening my coverage area. Because some people do not look at all sections, they go to one section everytime and thats all they do. I know no one likes multiple posts, but please do not school me, i have been a member alot longer than my info says. No disrespect, and thanks again for the info.

Re: Heater Bypass Valve Removal Pics
Here you go sorry it's dirty but should help. The last pic is a little hard to see but what I did was cut the hose coming out of the intake just enough to rotate it and connect it to the heater core and I plugged the steal hose on the frame with a cap and make sure you plug the vacuum line as well I cut that short an plugged it so you can't see it

Re: Heater Bypass Valve Removal Pics
I finally got some good weather to get my car out of storage, and get to work on some things. I go the coolant bypass valve removed and hose rerouted. i just made a 90* "L" out of hose to go from the back of the intake to the heater core and then just plugged off the port on the metal tube, filled the coolant back up and fired it up and no leaks! It made the engine compartment look a little better.

Re: Heater Bypass Valve Removal Pics
Interesting thread. My 82 didn't come with a heater valve.
I blew up a couple of heater cores under high revs so i
found a nice out of the way location to mount one. I used
a 89 GTA heater return tube and some creative routing.

Re: Heater Bypass Valve Removal Pics
about 5400 rpm she blew and i immediately let go.
Second time i was already shifting into 3rd and again
water all over my interior. The valve solved the problem
and i now have new carpet... lol
EDIT: i had to add the vacuum line and the a/c control
panel with the heater valve controls.

Jupiter that is a nice engine bay! I cannot figure out, it looks like you have a ton of space. Nice bypass valve routing.

Re: Heater Bypass Valve Removal Pics
Not having the wire harness' all all exposed on the
fenders and motor i think is why it 'appears' spacey.
It didn't appear this clean with the original v-belt
setup either. A/C was on the other side and routing
sucked.

Re: Heater Bypass Valve Removal Pics
Oh, ill never see 5400 RPM, I usually never go over 4000. I dont see though how you could blow cores, wouldnt a hose go before metal?

Re: Heater Bypass Valve Removal Pics
I hope that your problem was the exception, and not the rule, tons of people have done this and that is the first time i heard of someone blowing a core.

Re: Heater Bypass Valve Removal Pics
Can i just bypass my heater core? Like just take out the hose between the back of the intake to the heater core and plug both? Or how do i go about bypassing the core. I dont use heat anyway. I usually only drive it when its nice enough to take the t-tops out, and its stored during winter.
How hard is it to take off that hard steel line that runs on the fram rail. How is it mounted in there.

Re: Heater Bypass Valve Removal Pics
That steel tube is very simple to remove. IIRC, it's just strapped-down and bolted with one bolt.
I responded to your other thread about this, and yes, you can do all the different configurations you've asked about, removing all related hoses, then plugging and capping-off all the open ports.
But from the pic you posted here, it looks like you've got it set-up just fine already. Even if you change it further, you won't clean-up the look of the engine bay much more than you already have. And I really doubt you'll ever have any problems with it this way. People have been doing this for decades, and I doubt the lives of many heater cores have been sacrificed. And this way, even though you think/say you'll never use the heater, at least you'll still have it. Because you never know...
You might be out with a date, it's a cool humid night, and you end-up fogging up all the windows. Sure, you can figure-out ways to keep your date warm, but depending on how far you've gotten, you might not have any material to wipe-off the windows. It might be kind-of embarrassing. So always be prepared... with new dates... and old cars.
