"The stock S-series radiator is prone to cracking. Many many Saturn owners have replaced their radiators more than once due to this problem. We solved this problem by making a full aluminum radiator for their chassis. This particular model uses a 1.5" core, and is tig welded, and then pressure tested once completed. The unit includes all OEM provisions, and can use all stock hardware such as the factory ac, and radiator fans. This is a product with limited availability. Contact us today to check on to see if we have one available!"
