Whether you just want a replacement BMW 3 Series radiator or want to upgrade to something more suitable for performance-minded driving, replacing your old radiator can offer peace of mind from knowing that your BMW 3 Series cooling system is at its best. Don't try this at home, but we've been able to touch the tops of thick aluminum racing radiators in cars that were at operating temperature without getting burned. This was by accident, of course, but the point is still proven that an upgraded BMW 3 Series radiator can work wonders for your ride!

Radiators can be made of copper, plastic, or aluminum, and their cost is often determined by the thickness of materials and how the coolant is designed to flow within the core. Aluminum BMW 3 Series radiators are popular because of their light weight and because they dissipate heat quickly, although copper BMW 3 Series radiators can also do a fine job of cooling in most instances. Some radiators have plastic end tanks, which can help save some money since they tend to be less expensive.

Q: How do you install a radiator?
A: Radiators are manufactured specifically per vehicle application to ensure the best in fitment, just like your original radiator. Remove your factory unit and install the aftermarket radiator in its place.

Q: What is a radiator? Why buy a radiator?
A: A radiator is a device that cools the entire engine by using a water and antifreeze mixture. The mixture flows through your cooling system, passing through the radiator and back where it is cooled again by convection with the air. Aftermarket performance radiators offer 30% more cooling than standard radiators in many cases, and are great for high performance motors. When your engine is cooler, your car performs better and can go faster.
