LS-coupe cooling saga continues :(

[dville_gt]

little more water than coolant but about 50/50% ethel

What's your coolant mix and type?

[dville_gt]

Not at all, I'm throwing out ideas to try to help. The pictures are pretty cool, and basically say yes with proof.

makes the factory belt routing look pretty complex vs. my belt routing (guess thats what happens when you are only spinning the water pump and alternator.

[dville_gt]

the ect sensor for the pcm is located in the front of the drivers side cylinder head (oem location), the autometer sender is located in the rear of the passenger side head (same location as the oem just on the opposite head).

hey, i didn't say yes!

(hope you didn't take my response as sarcasm, i am looking for any help, hints, etc. i can get, i just made that to illustrate it)

Where is the coolant temp sensor located?

[dville_gt]

Cool

I still say fans and air blowing around the core support. Stopped the fans look like they are not pulling thru about 15 percent, driving on the highway your air is going everywhere but thru the radiator especially with that monster condensor in front of it. You need a custom shroud that encompasses the entire cooling area orrrrr get a griffin with the fan built in.

Did it do it when it had no ac on it? I know you drove it around then.

There are only three rows that are not encompassed by the fan shroud. Otherwise the fans/shroud meet up and seal very good.



As for air while moving I can see what you mean there and will take care of that issue by building some deflectors and a dam for it, but the car actually does better at speed (not that it doesn't have a problem there, but it can actually maintain temp at speed, its idling after driving around that is the biggest problem.

I did drive the car around, it wasn't quite this hot then, but the car did pretty good temp wise. I've gone through my tune trying to see if anything in the tune could cause the car to overheat but have not found anything, only thing I changed after adding a/c was to give it more base idle air with a/c on as it had trouble compensating for the additional load.

Car runs between 20-25* of advance at idle, wideband shows the car to be 4-5% rich at idle, (narrow bands seem to confirm this reading), manifold pressure around 70 kpa.

yes

Cool

You did check to make sure it is rotating the correct way, right?

[UserX]

Your fans behind the radiator are pulling, not pushing, right?

[greenbullitt]

Good things, I hope ! Lol ! How ya been, Paul ?

-Aaron

we were discussing the couple cooling issues you had and how they were curbed. Im good! hope youre doing well!

I havent got to see the car yet, merely been bouncing ideas, but hopefully I will get some hands on and find the issue at hand

you cant change the way it rotates unless you put the grooved side of the belt around it

Pump is the stocker off a 2005 Escalade LQ9. Only difference between it and stock is the top of it has been tapped for the cross-over hose that normally goes to the radiator.

Before anyone blames this for my issues, this is a common practice among the swap guys and "2165 Turbo Rail" with the GTO has his pump done the same way and stays cool (even with a turbo/intercooler adding additional heat). In addition, I only drilled/tapped it after I switch from the f-body radiator to the double pass that has no provision for a crossover tube.
