Oil coolers have me confused!

Oil coolers have me confused!
Hello there I have an 05 c6 with the z51 package. Believe it or not I just found out my car has the oil coolers which I previously thought was exclusive on the zo6.
So I bought my car wrecked with damage in the front. I have since repaired it and added the widebody in the process. So I am wondering are these oil coolers external or internal. I see the engine, power steering and tranny lines going to my radiator. My question is what does the oil cooler look like?

I have an '05 Z51 too but I don't know if I have the oil cooler or not. I seem to remember reading that they came on manual tranny only and I have an A4 but I'm not sure if I'm right or not. I don't know what they look like either.

On the backside of the radiator, at the top and bottom of the plastic end tanks....if you have hard lines entering the top and bottom of the passenger side tank you have a trans cooler. If you have hard lines entering the top and bottom of the driver side, you have an engine oil cooler...applies to 2005-2007. In 2008 the engine oil cooler moved to to an external unit located forward of the radiator.
Check your glove box for RPO Code "KPS"

ok so oil coolers are just the fact that there are lines going into the radiator from the engine tranny and power steering? That constitutes having oil coolers?
And also will a zo6 radiator replace the radiator I have now on my c6 with the tranny and engine coolers with no problem?

It looks like this...
Engine oil coolers on our Vettes are either fluid-to-fluid heat exchangers or air-to-fluid. Beginning in 2008 manual transmission Z51 cars had this air-to-oil cooler which mounted forward of the radiator on the driver's side.
A common upgrade to the smaller Z51 oil cooler shown above is the Z06 cooler (below). While the Z51 cooler is only 7" wide, the Z06 cooler is a full 22" wide and spans the entire width of the radiator. It is a direct replacement for the smaller Z51 cooler. It uses the same oil lines as the external Z51 cooler and uses the same mounting holes on the driver's side. You do have to add two holes on the passenger side of the plastic baffle for the mounting bolts...easy enough.
The Z06 radiator DOES NOT have an internal engine oil cooler, only a transmission cooler. The general consensus is that 2005-2007 automatic transmission Z51 cars do not have engine oil coolers...only the manual transmission cars do. The radiator below has transmission (automatic or manual) cooling only.
If your car has both the EOC and TOC it will look like this...
There is another variant which has neither an EOC nor TOC. It is used with the non-Z51 cars that have a manual transmission. It's the one in the foreground.
And finally, there is the ZR1 radiator...$$$$$$

The power steering cooler on the Z51 has nothing to do with the radiator. It mounts behind the radiator on the cross member just forward of the steering rack.

Do the non-Z51 man trans cars come with a smaller core radiator? Replacements very in price greatly $$$ And will a replacement Z06 radiator drop right into a 2005 Z51?
