When it comes to keeping your engine cool, the CSF Engine Coolant Radiator is a solid choice that I can personally vouch for. This isn't just any radiator; it's built with an OE style design that really gets the job done. If you're like me and want to extend the life of your ride, investing in a good radiator is crucial. A faulty cooling system can lead to some serious headaches down the line, so replacing it with something reliable is key.

Now, let’s talk specs. This radiator features a downflow design with a single row, making it efficient yet compact. The core measures in at 12 15/16 inches long and 27 1/16 inches wide, with a thickness of 5/8 inches. It's made from aluminum, which is lightweight yet strong, while the tanks are crafted from high-quality plastic. This isn't just any plastic, though; it's virgin grade and engineered to be tough, with glass filling for extra durability. You can feel good knowing it’s built to withstand the elements.

The inlet and outlet are conveniently located—upper driver side and lower passenger side, both with a diameter of 1 1/8 inches. And if you're concerned about oil cooling, this unit comes with a high-efficiency concentric type oil cooler measuring 13 3/4 inches.

One of the standout features is the multi-louvered fin design, which maximizes cooling performance. Plus, each radiator is 100% leak tested before it leaves the factory, ensuring it can handle 150% of standard operating pressure. Talk about peace of mind! And let’s not forget about the packaging—CSF goes the extra mile with a 10-foot drop test standard, so you know it’s going to arrive in one piece.

CSF has been in the game for over 50 years, producing high-quality radiators that fit a whopping 3,200 applications—from Acura to Volkswagen. They really know how to engineer radiators that meet high-performance standards, and with over 30 million units sold, they clearly have a good track record. Their manufacturing process is top-notch, with wind tunnel testing for cooling performance validation, and everything is assembled with care.

For those of you with a Mazda Protege (1999-2003), this radiator is a direct fit. Just a quick tip: make sure to use a mini, 16 psi cap when you install it, and always check the old cap for wear and tear while you’re at it. You don’t want to overlook those little details!

If you’re serious about keeping your engine cool and running smoothly, you can’t go wrong with the CSF radiator. It’s a smart choice for anyone who values quality and performance.
