BMW Radiators for BMW Z3 (1996-2002)

Clear BMW chassis

We sell only OE supplier or approved aftermarket upgrade radiators for your BMW. It seems BMW took some shortcuts when it came to radiator design and used weak materials like plastic for critical connection points. If you are tracking older models like E30, E36, or E46, you probably are well aware of these issues. As these cars age, the plastic pieces become more brittle and failure prone. The solution is to replace with upgraded radiators that perform as upgrades for the original, failure prone radiator to avoid being left on the side of the road or, worse yet, the track.

Every hero has its Achilles heel, and for many BMWs, it's the cooling system. Featuring an overabundance of brittle, crack-prone, leak-inducing plastic, the otherwise robust drivetrain is let down by a weak cooling system. Now, ECS has come to the rescue with a solution to cure those problems once and for all and leave the days of cracked plastic end tanks and coolant-stained driveways far behind. This radiator was designed with performance, durability, and good looks in mind to create a great all-around upgrade for any E36 owner, from the daily driver to the weekend warrior. Featuring fully aluminum construction, all the joints are precision TIG-welded for superior durability and show-car looks, with polished end tanks further adding to the great look of this radiator. The easily-stripped plastic drain plug and fan switch holes have been replaced with threaded alloy bungs in the stock locations, and the weak plastic tabs for the factory fan shroud have been replaced with beefy aluminum as well. Designed as a drop-in solution, this radiator will fit like a stock replacement, but will look and perform far better, while costing substantially less than the competition. What are you waiting for? Upgrade your cooling system today and leave your worries behind - and look great doing it - with this ECS Tuning Performance Aluminum Radiator. Note: Owners of automatic E36s utilizing a stock-style transmission cooler must drill two small holes in the lower frame of the radiator.
