Does anyone know if these wires actuate a solenoid or anything insode or are they just sensors? Im going to remove this box and and everyhtting connected to it but keep the smog pump and run a single hose from the pump to my cat just for being safe.

But I want to knwo what these wires connect to and if it will throw a code.

Thanks!

Can I get rid of that coolant router too?
it would be nice to get some new hoses and clean it all up. I see there is a line for vacumn maybe connected on it, what is that for?

Thanks!

underneath that plastic covers, lies two solenoids, that are controlled by the ecm, that divert air to the cat, and air injection. Read a shop manual for the car, about how it diverts the air and when. If you remove them, there shouldn't be a problem, because the computer doesn't know if they are working or not, theres no sender to tell them if they're working. Thats probably what I'll be doing on my 89 formula350.

i would keep the coolant diverter vavle, maybe just relocate it.

basically when u turn heat on thats when it becomes in use i think.

SpeedJunkie

Yeah I thought it had to do something with ac or heat so I quess ill try to hide it with some different hoses somewhere.

Is that what you did MD?

MdFormula350

na just left it there, with a/c gone and a.i.r gone it gave me plenty of room.

Well, if you removed the AC than the heater valve is useless. It stops the hot coolant from circulating through the heater core while the AC is on. Mine is gone and my heat works just fine

SpeedJunkie

So I could actually remove this now since I am removing my ac?

How would I route the hoses?

I would love to get rid of that stupid black plastic router....Im pretty much doing what MDformula350 has done and I want that thing gone!!

i still like to just use the blower on the heater box to blow outside air without heat so i am keeping the coolant diverter at least i think that has something to do with it. either way it doesnt bother me to much.

If you want to be able to use the fresh air vent, for cool air flow in the summer, you'd better leave the heater valve on there. Your heat will work just fine, you just won't be able to turn it off. That valve by-passes the heater core for ANY setting where the temp slider is in cool.

Bah, that's what the ttops are for

Well I have already bypassed the TB. So I just ran the input hose (5/8") from the front of the block to the firewall. I shortened the end of the metal tube on the output hose side (3/4") and ran the hose from the tube to the radiator. I'll post a pic in a few.

I don't have t-tops, damnit. I like to run the fresh air vent at night during the summer when it's raining. My car doesn't have rain gutters on it either, and with the side window open enough to let in any air, I get wet. I'd be willing to bet that you don't cruise around without your tops out while it raining. Then what do you do? Huh? Huh? I'm just kidding.

I tried to keep all that crap when I did the serpentine conversion this last week and I almost ditched all of it. Just keeping the diverter valve cost me about $25 and close to two hours of time. It's all hooked up and working great though.

I'm now working on a throttle body bypass, that is switched. That way, when it's cold as hell (but the roads are clear), I can open it up, and when it's nice out, I can close it. I'm going to do it so that the valve is concealed and the control is hidden as well. I had it bypassed, but on Christmas, it wouldn't run right on the highway. I hooked it all back up at my friends house, and it ran great on the way home. I love how well it runs in the summer, with the throttle body bypassed, just not in the winter.

I ditched the AC as well. I left the heater control valve connected, just re-routed the hosed & mounted it to the inner fender. BTW my heat works great too & I can also turn it off in the summertime.

it should be noted that that heater diverter valve was put into use in 87. my 86 does not have it and is much cleaner setup, but i am assuming there must be a vaccum solenoid under the dash somewhere to stop coolant flow. if you really wanna get rid of the ugly valve, get the heater hoses and stuff of an 85 or 86 TPI car and you will be set.

The long hose over the valve cover is only temporary. I took out the AC in the summer and didn't get a new heater box til winter and needed to get the heat working quickly.

92TRANSAMWS6

hahahaha.....well I have woke up once to look outside and see that it was raining while my car was in the driveway with the tops out

I'll just bypass the core totally if it becomes aproblem in the summer

SpeedJunkie

Well I quess ill keep the valve cause Ive been in a car without one working (now that I know how it works) Ill probaly keep it how it is. At least all the ac stuff and air tubes will be gone!

Thanks for the link to the pic, 92TAWS6.

Pretty much what I'm looking to do, except I'm trying to keep everything off the valve covers. My 87 still has the v-belt setup, so the alt is on that side. Looks like all I'll have to do is figure out how to get the hose around that, since I'm going to run them down the inner fender to the firewall. And the return line I'm connecting to the crossover at the bottom (where it originally went).

FYI, for all those that concerned about shutting off flow to the core during the summer, why not just install a manual valve in the input line?

SpeedJunkie

Yeah I was thinking Ill do that eventually its just I thought I could originally get rid of it becuase I thought it only had to do with the A/C but for now Im gonna leave it.
