Product Details

This is a Koyo aluminum radiator, designed to replace the stock unit in a wide range of BMW 3-Series models from 1988 through 2000, including the E36 M3. It's built specifically for manual transmission, 6-cylinder engines, ensuring it bolts right in without modification for those specific applications. A well-built radiator is crucial for keeping your engine temperatures in check, especially if you're pushing your BMW a bit harder or just want the peace of mind that comes with a solid cooling system.

Koyo uses aluminum construction for this radiator, which is lighter than the original and also helps dissipate heat more effectively. This means your engine can run cooler, reducing the risk of overheating, particularly during spirited driving or in warmer climates. The design aims for direct fitment, meaning it should line up with your existing mounting points and hose connections, making the installation process more straightforward for a mechanic or a DIYer.

When you're replacing a radiator, it's always a good idea to check your hoses and thermostat as well. This Koyo radiator is a solid option for BMW owners looking to maintain or improve their cooling system's performance.
