Right.. well tahts called the "stu Mod".. This is called the option B...

they arent the same.

 

here is the one from zzp

 

1.Short your killing me here... is the diagram correct than or not!?! When I think of overflow I think of every once in a blue moon a little coolant will come out.

2. No coolant will really every go to through the 1/4" bleeder hose correct?

3. Coolant just flows back and forth through the 3/4" hose from the TEE to the surge tank?

Thanks

ok but that does not show option B...

 

change the filler neck to a option b.

 

yes.
for my option b tank, i just put a screw in it. to keep crap from going in.
its never gonna fully fill up.
don't even worry about connecting the bleeder hose anywhere

 

Lol..

The diagram where i said "good job " is correct...

This tank is not flow through... There is 1 3/4" hole (where it goes into the T) and i think the other is 1/4" for the bleeder line to the H/E..

Im unaware of that. That is done with Stu mod... not the option B from what i understand.

 

Ok try to stay on track here guys... this diagram is showing and extra heat exchanger/ dual pass/ and OPTION B (not the stu mod) So, Option B only has one 3/4" hose connected to it. It also has a bleeder line going to the stock heat exchanger. Can anyone explain how fluid comes and going from the option B tank if there is only ONE 3/4" hose?!?

 

Because it is an overflow tank... It does circulate though, since it is a slightly pressurized system...

 

Ok so to circulate through you are saying that fluid comes from the TEE in a 3/4" hose to the coolant tank and than drains to the stock heat exchanger though the 1/4" hose with the orifice inside of it? Does anyone know if any fluid even goes through the 1/4" hose? I assumed it did not.

 

so the diagram from zzp is not an option b is for? if you replace teh filler cap with an option b tank?

 

No man... There is only ONE in / out... the smaller hose is a bleeder, for when it over flows... Nothing drains..

 

As far as i know, you do NOT remove the filler cap...

 

NO if you replace the filler cap with a tank and just have coolant flowing through it that is what I believe is considered the "STU MOD" (flow through tank design) Option B is different I believe, I am trying to help myself and other understand it.

 

i think you should create a diagram so we know wat you mean.

well which one cools better? the stu mod or the real option b?

 

I'm pretty sure you remove the filler cap for option B because you can fill it through the option B tank,

No one has numbers for which one cools better. They both do basically the same thing just are design slightly different... look at the image from ZZP and just replace the filler neck with a tank with two 3/4 fitting on it, and than you are adding more fluid to the system and there is a constant flow through the tank... this is differen than option B.

 

Okay, i looked it up..

You do remove the stock filler neck for option B installation.

The stu mod is a different tank than the option B.. they are two different things.

I like the stu mod because it is a flow through type....

the option B itself is not a flow through tank...

 

i'm gonna stick with my stu mod. and add my dual pass and go with zzp diagram. its looks like the same with schamsy but he got a bleeder hose.

 

Alright CLICK HERE to very the STU MOD. This is not the OPTION B mod.

What does everyone think?

 

This is correct.

 

What you should do is this...

Run the diagram like the ZZP picture but replace the stock cap with option B and tap another 3/4" fitting into the tank to make it flow through...way better.

 

Yeah after looking/thinking about it that is what I am going to do. I hear bleeding the system is a b*tch though. Any suggestions?

 

So is this all there is to the Dual Pass / Aftermarket H/E / Flow Thru tank? Doesn't seem too bad. I would imagine I should be able to get an extra gallon of coolant with this.

 

Yup...

With the flow through, it takes all of but 5 minutes.

 

hey question? will it hurt if i switch the pump around? like its pointing to the driver side. so if i switch it pointin to the passenger side will it affect the pump? cuz the option b is on the passenger side.

 

There is no reason to switch the pump around.
