HELP!! Dual Pass Laminova core positioning
 

I have found a few how to's and they have different pictures about which way to put the cores. which is better?

A (Source):

or B (Source):

or C: It does not matter?

if your goin dual pass go with the first pic but swap you flow directions

it all depends on what way your going top run the coolant in the plate. the idea is you want the coolant going into the small holes in the cores and comming out the big ones. i run the coolant into the center of the plate and out the 2 outer fittings, and that being said my cores are setup like the 2nd pic.

OooO contact ebristol on RLF for details.

x 2 :)

^^^ assumes two inlets and one outlet... (i think)..lol

If you read the gm suppplied instructions.. the picture and the text instructions don't agree... LOL..

^^^ thats a cool pic

And so that agree's with which picture in the original post?

For the curious, From the laminova engineer himself:



The plugs in the centre hole of the cores normally should be located on the coolant inlet side (upstream). If there not, in most applications it should not be any problem. For some applications, the plug can come loose, but only for high system pressure applications.

Thanks for the help everyone!

if your running dual pass...ur picture B is the correct way of doing it....the little holes are inlets, so they go on the inside, since ur inlet is in the center, and the bigger holes r outlets, they go on the outside bc the top and bottom tube are outlets...so once agian picture B is the correct way of doing it

see thats what this forum is about...

great advice from people who know what they are talking about.

that will tell u how to run the hoses goin to and from the manifold..if you dont have a filler tank and are still using the factory filler neck, than pretend the tank is a neck : p same concept applies, inlet comes from manifold, outlet goes to your h/e

Assuming that your pump is wired correctly, you are sending the hot coolant up through the manifold, and in the outlets of the laminovas and out the inlets of the laminovas, then through the overflow, then into the heat exchanger, then back to the pump.

In short, your shit is backwards son. Though, your pump isnt really illustrated properly.

the pumps outlet faces upwards, the inlet ifaces away from the pump, i know i drew the in let off a bit :p but you should be able to figure it out....and the pump will flow no matter how u wire it...the top will either suck or blow pending how u wire it up...i know, i played with it when i had mine off :p but mine is wired so water egts sucked in from the h/e, and shot upwards into the center tube, and thru the cores inlets, and out the outlets ont he top and bottom tubes, than they join to one and go into the fillneck, than back to the h/e, and the system continues, so cool water goes thru my manifold

Agreed, but you are doing it wrong. The outlet should flow into the heat exchanger (this makes that hose like 6" long and gives the hot fluid out of the pump immediate cooling), from the heat exchanger to the overflow/resovoir, then into the two inlets of the manifold, then out of the single outlet gravity fed into the pump. I think this is even how the GMR instructions dictate it. The idea is to have the cooler water in the overflow on reserve, so you can fill it with ice, not in the heat exchanger.

ah the tank yes, i see what u mean lo, yeah bypass the tank :p pretend its the filler neck :) thats how mine is done

I know, same thing though. You are just substituting the stock overflow for the bigger resovoir. Fluid should still flow the same direction though.

yup yup

:cussing: I give up.

Hey, source b is a pic from my install. How'd that get there. LOL.
