need help with the coolant lines on a mini me. a6 bottom, y8 head, z6 manifold. i have the tb and eacv lines and all the large coolant lines routed. there is one vacuum/coolant (not sure, but its a big hose) coming out of the drivers side firewall and i dont know where it goes. on my a6 manifold it connected on the drivers side into a little adapter but on the z6 that is not there. also one line comin off the head (by the cluster of 3 or so other coolant lines) is sitting by itself.

 

The big one sounds like the brake booster vac line.

Got any pics so we can see the lines?

 

no not the brake booster, its next to it tho , comin outta the firewall int he same direction. it originally plugged in on the drivers side of the intake manifold, a little metal adapter came off the side.

 

Are you sure it's not the fuel return line? Thats the only "line" that I can think of that's near the brake booster.

 

^^ that was my thought too ^^^

The only problem I could see you running into if you hooked all the hoses up right. Is a coollant line on the passenger side. which I ended up Teeing up

 

ok so i figured that one out, it ended up going to the fuel pressure regulator. now i have one more line i cant figure out, which is a coolant line, it comes out of the passanger side, i cant tell if its on the head, block, or intake manifold, but its on that corner where they all meet. its a6 bottom, and z6 manifold, everything else is hooked up, this one is sticking straight up.

 

Is it where all of them go to the intake arm? If so you will need to T this one off. Theres one coolant line that exits the (its right below the TB forgot the name of it).


.. to better understand the area I am talking about it is the one that comes from the IACV on the back of the intake manifold and goes to this one that is located on the bottom of the TB then goes to the cylinder head or block....

Just T it off with the correct adapter and you are good to go.

actually, ok i know its hard to describe, ill try to get a picture later. the line i believe im trying to figure out is coming out from the intake manifold underneath the number 4 runner. in that area there is a group of other coolant lines, one going to the eacv (got that one), then a fatty one doing a 90 and going into the , i think its thermostat, and maybe another but i forgot. anyways the one i need is right under the numbre 4 runner ona z6 intake and is sticking straight up, i have everything else hooked up, hopefully correct. it has a short line also. so im understanding that one line needs to be closed off? or connected in line with another line? either way, im hoping i got the ones correct so far, i tried to just go with the flow and use the lines and how they were shaped to figure it out.

 

I am still guessing its the one I am talking about. A picture woudl be nice. If it was running to the heater core it would be pretty big.
