1 inch 3800 Radiator

SKU: ZZ-1RAD38

$129.99 Sale price

Regular price $129.99

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.

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.

Not a direct fit for 04 GT but works

I bought this radiator not realizing that it wasn't for series 3 cars, but I still managed to make it work. You'll only have one bolt on the divers side that lines up and the radiator support at the top, but it still will fit tight enough with minimal play. You'll need new transmission line connectors (the fittings are smaller than the ones on the series 3), and you'll need a 97-03 radiator cap. A little extra work but definitely worth it. My temps don't even reach the halfway point in the 100+ Texas heat in traffic with the AC on! Plus it's cheaper than OEM. Best mistake I've ever made. Thanks ZZP!

Radiator as advertised. Dropped 18deg

Bought this as a replacement for my stock 5/8" thick radiator on my 02gpgt. I have ssm90, ss intercooler, 1.9rrs, full intake and exhaust and other supporting mods with a 160tstat. On 90 degree days with the ac on, my scan gauge read 210deg. Coolant temp. Causing blips ok knock upon light acceleration. With this installed instead, the most I've seen is 192deg coolant temp. So I dropped 18 deg with the ac on. I expected more but I am satisfied. It's a high quality product, no leaks yet. Fit was 100%. No modifications needed. 3hr job max.
