: Radiator with internal or external trans cooler?

11-06-12, 02:43 PM
I need to know if the radiator I have has internal or external trans cooler. The part number that the dealer gave me when I called was 19130399, and they said it was the one without the internal trans cooler. If this is true does that mean I have an external one? When I look that number up it comes up as a radiator for an 08-09 STS. Maybe it is the updated or superseded part number?

I have attached 2 pictures. Is either one of these the external trans cooler?

In the of the radiator, is just the back part the radiator or are both parts the radiator?

Trailer package 1sg have external. Easiest way to tell is pull the front upper engine dam look between the rad and condenser if you have it you'll see it between the two.

I don't have the 1SG. When you say look between the rad and condenser what is the condenser? Is that the part that is in front of the radiator? And what would the cooler look like in between the two? There is something in between them but it doesn't look like a cooler it looks like it just connects the two.
