Well I finally got a chance to work on the heat exchanger project. This is the first 100% bolt in unit for a reasonable price. Over twice the thickness of the stock one with much better flow characteristics. Single pass design is more efficient than multi-pass designs.

Looks great. I might have to start spending some money your way.

Looks like it will perform much better than the factory unit. Its too bad that its so visible behind the V grill, the look just isn't my taste. Do you think painted endtanks would make it look more "factory"?

You could always dust it with satin black paint to make it less visible. That's all the factory does. I don't think it affects the heat transfer too much as long as you don't drown it with paint.

Yep mine on my 06 just one coat of black and you can't even see it. Looks good Timmy might get that for the new car see how the d3 stuff works first be for I take it all off..

How much of a temp drop have you seen in your IATs with the bigger heat exchanger?

What all is involved in terms of parts and install. $299 is a great price. Yea, I know, remove the front bumper cover... :D

There is too much snow on the ground to do much testing right now.

It comes with bolts and hose to tie into the stock piping. There is one tee fitting on the inlet side of the pump that needs to be turned around but that's pretty much it.

Do you need to upgrade the coolant pump to compensate for the extra volume?

TimmyC
02-04-13, 08:29 PM
A coolant pump upgrade is not required to use this heat exchanger. It doesn't matter how much coolant is in the system; the pump will circulate whatever is in there just the same.

where did you get the blackhousing headlights or did you have them taken apart and painted?

Had to paint them. No one makes aftermarket assemblies for these cars.

Hey I have 2006 sts v I was curious where do u purchase this intercooler and what what r temp drops my high is 228 and my low is 207. I have an air intake 1 and 2 and a maga flow exhaust system. Would fuel injectors make a difference in temp? Where can I contact u ? My email is constantinomarkadakis@yahoo.com. Thanks

Your intercooler pump is broken. I can get you one for $109 shipped. Email me at t_coel@yahoo.com to purchase.


What should his temps be? those are similar to mine in 90 degree weather Sub 230 after a few hard runs a little over 200 in city traffic.

TimmyC
03-22-14, 03:39 PM
110 cruising, 150 at the end of a wot run.

Your pump is broken too.

Or all the coolant leaked out.

Why would anyone be talking about oil temps in an intercooler thread? Those temps are fine for oil.

I thought we were talking about air temps.

Me to so don't feel bad.
My intake temps only ever got to 220-230 and that was with 18,5psi and a non working pump. With stock boost and a working pump 190 would be high. And no they are not in the dic you need a computer to read them.

Whoops but I do need an exchanger. By the way when our cars heat soaked on lets say a 70 degree day how much power are we down?

The coolant temp isn't displayed digitally right? I only have the oil temp, oil pressure, and trans temp

Because the intercooler systems (Charged Air Cooler as GM calls it), is a completely separate system from the engine's cooling system. Yes, both use Dexcool. But they are two separate systems.

Tim, I gotta do this, this spring. What is the total cost of this whole bolt-in setup?

Is this pump covered under warranty? Just Curious.

how much coolant is this intercooler adding to the cooling system if any? does using this intercooler replace having to use a 1 gal reservoir + OEM/FMEH combo?

1madstsv
05-13-14, 07:55 AM
It adds .75 gal if I rember right. Witch it 2x more than the stock one held. You take out the stock one and add this. That's all you need.

Sorry for resurrecting the dead, but I'm doing this on my buddy's lift next week. Are you guys removing the factory heat exchanger when doing this, or are you just eliminating plumbing to it and running up to Timmy's? For shits and giggles, would it be possible to run both simultaneously, or would that overwhelm the pump? Dumb questions, I know, but was wondering if running both would increase the cooling effect because of the increased airflow over the cooling fins and the extra coolant volume...would be about a bitch to purge, though...

You pull the old one and replace it with Tim's keep in mind to lightly paint it if you don't want the exposed look

4 bolts hold the HE on, hoses will mate right up with the parts tim sends, may as well change all the coolant for the engine at the same time, also take your time getting the HE in place to be careful not to damage the cooling fins.

TC fab heat exchanger in. Easy job. Longest part is the damned body work removal! Had to cut brake tubing as spacers to fill the space between the radiator support and the top heat exchanger brackets, as I was hesitant to bend aluminum ears to welded to the top of the exchanger to pull it tight. Without bending the ears, or without the spacers, the top center of the heat exchanger body pressed into the lower protrusion of the hood latch assembly.

for fear of cracking the welds. Longer bolts and viola! All in all the only sucky part is burping the system, which will take a couple more diving cycles.

cadi509

Told you not that hard it will take a few drives to get the system fully filled just keep topping it off

Rboughne1

Hey guys, quick dumb question. I'm in the process of burping the heat exchanger through the fill tube after each of my drive cycles when the car is cool. I notice that when I check the level cold now, there is zero fluid in the tube, but as soon as I take the cap off to fill it, the fluid rises right to the top of the tube. Keep in mind, once again, that the motor is cold, and I'm filling +4 hours after running. I tried starting the car and running it for a minute, hoping the pump would prime and drag the fluid down, but to no avail. As soon as I turn the car off, I hear fluid sloshing the hoses as the electric pump runs for a few seconds after (sounds like the pipes in the wall of a house after a second floor toilet flushes), leading me to believe that there is still air in the system. Is the system fully burped, or is there an air pocket I cannot get rid of? I checked the level mid drive, and there is no fluid in the tube when it is hot as well.

----------

Just crazy because as I go to fill, I can't! Tried squeezing the hoses to and from the fill tube as well, with no change...

----------

Sound is definitely the top of the heat exchanger filling...

Wait til the fluid is cooled then fill the tube the the excess pressure from the heat won't force the coolant back up

TimmyC
01-24-15, 10:06 PM
Fill the heat exchanger itself. Disconnect the top hose and fill it from there. You should be able to reach in there without disassembling everything.

I don't know Tim, I think it'll be more of a PITA than just cracking the rectangle on top of the charger, and filling from there...it's tight to get to it, and I've got big hands... If I'm going to fill it again through the top of the exchanger, I've hot to pull her apart...AGAIN.

Start it every morning, pop the hood, grab your coolant, open your filler tube, slowly add coolant.slowly is key.took me about a week to get it full.maybe also open the filler tube cap slowly.good luck
