Because I am the paranoid type, I use TWO B&M 24K coolers, hung off the back of the bumper bar. I have removed the OEM bumper cover grille, and drilled out the absorber and opened up the holes in the stock bumper bar. You can see the much of the coolers, through the holes, that I have modified. I then bolted up both coolers, next to each other, and put them in, in a slant. I have removed the washer tank, and both plastic air deflectors, in front of the condensor/ radiator, and installed a washer tank, from another GM car, behind and below the driver' s side headlamp. So far, even in 105+ degree Sacramento heat, with the A/C on, in traffic for more than a half hour, the temps' won' t go above 225*. Before, with all that other stuff in the way, I would see temps' get above 230*, and tranny temps' nearing 200*, under similar conditions. I had found, by using a fan, in front of the vehicle, that blocking the area above the lower air deflector, can lessen the amount of air directed at the radiator, and by removing the items I have, and installing the coolers where they are now, I can keep my tranny temps' below 190*, in traffic, and coolant around 225*, at the most. I think it just looks cooler and less cluttererd too. Most people seem to be fine with one cooler, either dope, or in front of the condensor/ radiator, but, with my higher stall, and high heat in the summer, I have spent much time in finally getting a setup I liked. I might have to block some airflow in the winter time, as on the freeway my temps' don' t get much above 155*, now, but, I can figure something out

.
My point, is if you go dope, you MAY not get air flow in traffic, and if you install it in front of the condensor/ radiator, you may likely increase you coolant temps' in traffic. With using guages I have found, what I think to be a suitable compromise, that with the exception of being too efficient in the cold winter, will keep my temperatures in a range I am comfortable, and at the track, in 90* heat, keep my tranny temps' less than 180*, after the runs.
