Cobalt Addiction Dual Pass endplate (for you M62 guys)

Here is all the marvelous hardware....




The actual end plate, not a bad piece....






I got the GM instruction manual for this part too....ehhh.
Overall, I'm a little disappointed with what I got after waiting nearly 600 years for it. The real disappointment is the piece connecting the two hoses is a T shape, I was under the impression that it would be Y shaped. I'm a little concerned about the flowing capabilities of it.

I bought it for $239 I think, but they were having problems with that model, so they went to TIG welding the third hose port on it, they said the price would increase, but I wouldn't have to pay it since I ordered before the new model.

A Y piece would still be preferable though, right?

The GM is the exact same price only difference being that its cast with the extra pipe fitting instead of tigged and the Gm includes no fittings or hose

I doubt a Y fitting would be much different than what you have pictured

once the coolant is flowing there shouldnt be but a minimal difference in flow

if you feel better with a Y , then find 1 the hose should be 3/4"


dam i think GM's is able that price

Nice....my next mod as well to the SC...

Got to get my new exhaust hung first and a few exterior things taken care of but I'll be interested to see how much more it cools.

Post up some info if you can get any and some installed pics.



Eh...old man with a Corvette now...it was bound to happen sooner rather than later right?

A fitting and a little tigging and you are done, you can get that fitting from Parker for less then $10. Much easier way to go, and you don't need to wait forever wither. Had my parts picked out, was going to be my Christmas present to myself.

you can

BUT you have very limited room , and it has to turn enough to seal , and point in a very narrow range

the end plate sits very close to the oil filter housing

Don't forget you have to run a couple of the cores around. That may be the issue if there isn't enough space to flip them without removing the lower manifold.

This helps to cool/maintain relatively cool iats.



It'll be a tough install. Removing the charger and the intake manifold will be a pita, so will putting it back on. Hopefully, it'll be worth it. I thought about making my own, but I don't want to deal with downtime, nor do I want to ever have to worry about it. That's worth it to me...if the T fitting will flow the same as a Y fitting and fit better, I can live with that. I'm happy with it now.

T fitting wont flow near as good as a Y fitting would. but thats not the questions your really need to ask because if the T fitting is allready flowing enough fluid to do its job the extra flow thru a Y fitting may not realistically gain you anything.

Honestly, I don't know.

I didn't start monitoring my iat's until after I installed it.

Stupid, yes, but I did it when I did my pulley.

If it helps though, on the interstate, my iat's are usually around 119* with a 3.2" pulley after a few minutes of driving, they don't increase.

You could probably make your own if you have an extra end plate laying around.
