OEM style 1” radiator. Replacing you old radiator results in better cooling for the engine and the transmission. This 1” core is much thicker than the NA radiators and serves as a great upgrade. For supercharged applications, this will bring your performance back to when the car was new. Old coolant tends to sludge at the bottom of the radiator. With the lower portion filled with sludge, fins being bent, and road debris getting in the radiator, many cars run much hotter than they should reducing engine performance and transmission life.

New coolant O-rings included for coolant level sensor.

Fits: W-Body (97-03 Grand Prix, Regal, Venture, Silhouette, Montana, Trans Sport).

Does not fit H-Body Bonnevilles, and Park Ave/LaSabre.

Excellent service

The part works as intended even tho it didn’t actually fitting my model vehicle. I was still able to make it fit with little to no problem.

Great product- Not a direct replacement for 04 Impala SS

I have an 04 Impala ss, this will not directly fit, you will have to modify the fan mounting points, also, there is not a mounting point on the "front" "grill side" of the radiator tank to mount the a/c condenser. Also the radiator cap is different. I fabricated brackets for mine, and had the leave the condenser sitting up against the radiator. Honestly I delayed writing this review because I don't want to sound like I'm bashing ZZP, I love their products, but..... I did ask customer service if this would fit my car before buying it and the response I received was "it should" and it didn't, that sucks. Luckily I have automotive experience and a shop. So my issues were more with the listing and not the product, that's why I'm giving it three stars, it does cool my car better, and my trans temps have dropped by about 7-10 degrees. Worth the money, good quality. Love you zzp, but I suggest cleaning up this listing a little.

So far so good!

Radiator fit perfectly. It was quite a job replacing but I've never replaced a radiator before. I also replaced the thermostat to 180 degrees one and the temperature has stayed around the 200 degree range.
