Mishimoto 2004 Pontiac GTO Performance Aluminum Radiator

Mishimoto is known for making well-built cooling components, and this performance aluminum radiator is a prime example for your 2004 Pontiac GTO. If you're pushing your GTO on the track or just want more reliable cooling for spirited driving, this radiator is a solid upgrade over the stock unit. It's designed to handle the demands of a modern muscle car, ensuring your engine stays at optimal temperatures.

This radiator features an all-aluminum construction, including TIG-welded end tanks for strong, leak-free connections. The core itself is a two-row design that's fully brazed, giving it a larger capacity of 0.64 L over stock. This improved capacity and efficient heat dissipation means you can expect coolant temperatures to drop by 15 degrees Fahrenheit or more, which is crucial for preventing overheating during demanding use. It also includes an in-tank transmission fluid cooler that works with your factory lines, making it a straightforward bolt-in replacement.

To help keep your coolant clean, Mishimoto includes their magnetic oil drain plug, which captures any stray metal fragments. This radiator is a direct fit for the 2004 Pontiac GTO and comes with Mishimoto's Lifetime Warranty, so you can be confident in its quality and performance for years to come.
