With the onset of cool weather in the desert....I would like to bypass the secondary radiators.

For those that have removed them...is there a simple way to loop a connection and bypass? I want to leave everything else intact because in 6 months i need those radiators again.

Do you leave this valve on the oe direction? Or flip the direction?

I just purchased similar hose at local car shop and plugged it in place where the radiators would normally go.
Just make sure you get good clamps. My first approach I found that the bottom connection would leak a tiny bit, and had to remove the bumper again to redo it. You can use some sealant where the hose and the existing metal connectors join.

Dave I pulled mine off a while back and just looped it back in but I think it is reversed. I will have to check. Mine does not seem to bad with them off and sure cleans up things a little more. Seems would be a hassle to bypass and then go back.

Yeah, I just need to know if you flipped that check valve? I see where you move the hose and bypass the aux cooler lines.

It gets 115 here in the summer. I need the extra coolers in the summer.

I'm of the understanding that you need to keep the check valve oriented in the same direction as it is currently. I had a photo of this some time back, but it confused people because I tried to show which way you didn't want the fluid going vs. which way the arrow is on the valve. If you compare the two diagrams below, it is pretty clear to me that the arrow direction needs to match what's shown on the 2nd diagram that is attached below which is dumping fluid back in to the pipe leading to the T-stat housing - arrow pointing towards T-stat from the take-off point on the frame. I'm no Audi service tech, but I'd need a pretty good argument to convince me of a different orientation than this.

You won't really get the full benefit until you remove the Aux radiators so the IC's can breath...unless you plan on doing that. Are you running W/M on one of the damn cars yet??? Speaking of cooling...

Primary goal is remove heat soak.

Is there enough flow restriction? Hard to say but i need the added capacity 5 months of the year so the system must stay.

No w/m for me yet.
