Coolant overflow tank + vacuum lines

bake82 · October 17, 2007, 11:07:01 AM

Hey Guys,

I'm hopefully finishing up my 3.1 turbo 5 speed swap tonight on my Cutlass, I'm hoping that somebody can help me out!!

Can somebody take a picture of how their coolant overflow tank is mounted and where it is located? I've seen a number of pictures, and the coolant overflow tank I have off Dave's Olld Turbo CS is mounted over the ECM and no other TGP's I've seen are. Wondering how/where the stock one is mounted, and if somebody can tell me how I can mount the one I have that mounts over the ECM.

If I mount the one over the ECM does that mean I do not need the black piece that would normally cover it? I'm confused as to how it goes together since I've never seen one like this and did not take it apart.

ALSO does anybody have a picture of the vacuum line routing for a TGP? I can't find it, and I need to know how they were routed. Unfortunetly I do NOT have a TGP handy to go outside and look at!

Any help ASAP is GREATLY appreciated!!

Thanks!

93luminaZ34 has his coolant bottle mounted over the ECM on his TGP.

I have the vacuum line routing diagram here somewhere... I'll post it up in a minute.

Hey guys!!

Thanks a million!!

I After looking at a few pics of Matt's TGP I see how it's set up.

Does anybody know where this hose goes to? See pic? highlighted with red box

(matt hope you don't mind..stole your picture.

It looks like it goes to the overflow tank...is that true? or where else does it go??

I replied to your post over on w-body. but that hose goes down to the heater core return pipe. (that runs along the firewall).

the ecm-over coolant tank just connects to a small tube that runs up to the fitting under the radiator cap. the hose that points STRAIGHT down off the bottom of the tank connects to nothing.

Matt you helped out and didn't even know it! LOL...

Anyways I got everything hooked up. boost Gauge, BOV, all vacuum lines, coolant lines, oil lines, turbo is in, coolant overlow tank is fitted in, just need some self-tapping screws and thats in.

I have a few more odds and ends to do(mainly bleed slutch hydraulic system and install), install axles and fill up the car with fluids...then I get to see if all my work has paid of and the Car runs!!!!

god I know what that feels like... hope it all goes smoothly for you.

this might be obvious but make sure you paint over the self tappers, on both sides.. otherwise the body's gonna start rusting there.
