That radiator is the 'air' part of your transmission ATF cooler. The 'liquid' part is inside the passenger side of the radiator.

 

Learned something new again today. Thanks for clearing that up.

 

One send line to the lower in-radiator cooler fitting, then a jumper hose from top of rad to air cooler, then return line to trans.






RE: the '90-95 oil cooler ducting, I have no idea how effective it is, but at some angles it looks like the ducting is at least guiding some airflow:

 

What is this interesting thing...?

It's the newest style flux capacitor. Every time Rob goes 88mph he goes back in time 5 seconds.

 

Rob - nice! - so all of the above!

Did you change out the dash Cat symbol for something else? does the alert happen in multiple colors?

Alan

 

I was afraid to mess with the face of the gauge cluster, so no, no swapping. It's supposed to glow green when powered and flash red during alerts. I recall it flashing red during powerup but I never actually drove the car in anger, so I dunno.

 

Porsche designed the cooling system on these cars to operate effectively in severe dessert climates.

If you are overheating in idle traffic you need to improve the cooling fan(s) operation.

re. the oiler cooler - Porsche has a directive out that describes proper orientation of that front spoiler dam and how moving it will impede oil cooling efficiency.

I recall that Dwayne had referenced it in one of his write-ups.

 

wrt oil coolling they screwed it all up on the late S4 & GTS. You are probably lucky that its just not hot enough in San Diego to see just how far short they came here...for the real extreme desert climates

...or maybe you just aren't driving it fast enough

Coastal San Diego only approaches Phoenix when it's on fire. And even then, Phoenix is hotter.

 

I installed an external oil cooler and it made a big difference. After installing my Murf 3 kit I had cooling problems, both water and oil but now much better.

 

you have a parts list for that...???

 

Colin aka Lizard928 bought the parts and installed it for me so not sure? Lol

Colin can you pipe in and answer Tony?

He also fabricated the mounting bracket from some aluminum strip which worked great! We also cut louvers in the wheel well liner to vent the heat. I'll take a picture of that and post later.

 

i believe that is a B&M cooler. http://www.bmracing.com/products/702...&md=&smd=&eng=

thats the general idea i am thinking of doing.

please post pics of the liner with the vents cut, if you could good sir.
