The best radiator for the job of keeping your engine in top-performing shape comes straight from the OEM. You probably already know its job: fanning hot engine coolant, thereby dispersing engine heat, which helps prevent overheating. But how radiators work is a little more complex. Most factory radiators have core blocks with flat aluminum tubes and fins. Coolant flows from their inlets to their outlets. It gets compressed by a pressure cap along the way, enabling more heat absorption. The fins release the heat into the air. The cooler engine that results runs better. Some radiators use additional fins called turbulators to scatter heat even better. Some original radiators even have transmission cooler tanks that pass heat off to your coolant instead of spreading it into the air. That helps hotter-running transmissions work better. If your car overheats, however, you start hearing strange engine noises, smell syrupy ethylene glycol, or discover your coolant has discolored or built up, these are signs of radiator problems. So are leaking antifreeze, a high temperature gauge, and damaged exterior fins, not to mention trouble shifting, if you've got a transmission cooler. Even HVAC system problems can mean a bad radiator. Check your owner's manual if you think you're due for a radiator change.
