OEM GM Radiators

You may know that a good factory GM radiator improves engine performance. You probably know it does so by dissipating engine heat. It gets that result by fanning hot engine coolant, which helps prevent overheats. But how radiators work exactly requires basic explanation. Most radiators consist of core blocks that have flat aluminum tubes with fin designs. Coolant flows between inlets to outlets, compressed by a pressure cap that lets the coolant absorb more heat. The fins' job is to release that heat into the surrounding air. The resulting cooler engine just plain runs at its best. Some radiators also feature additional fins. They're called turbulators, and they dissipate heat dissipation even better. A lot of radiators even have tanks on their sides that hold transmission coolers. These trade transmission heat with engine coolant instead of diffusing it. That helps cool hotter-running transmissions. Eventually, signs of radiator problems can appear. You can start hearing strange engine noises. You might smell ethylene glycol, which has a syrupy odor. These aren't to mention that your coolant can build up or become discolored. You might see leaking antifreeze, higher-than-normal temperature gauge readings, and damage to exterior fins. If you've got a transmission cooler, you can start to have trouble shifting; this means your transmission fluid is probably contaminated, the result of a crack or another system issue. Even a failing HVAC system can mean your radiator is bad. The worst symptom, though, is an overheat.
