There's an oil cooler that is adjacent to the left side of the radiator, but it really isn't in an active stream of air while the car isn't moving.

I'm sure it helps some, as in better than not having it, but it isn't an optimal setup, compared to external coolers that have a fan or are in some good air flow.
