Factory GM Radiators

As part of your vehicle's cooling system, your radiator helps your engine run smoothly by preventing overheats. How it works is a process that begins with coolant, more commonly called antifreeze.

As your engine runs, it generates a lot of heat. The antifreeze, traveling back and forth (with help from a water pump) through radiator inlet and outlet hoses, traps the heat. A radiator cap pressurizes the antifreeze as it travels. When all possible heat has been absorbed, a set of fins expels it, and a fan helps disperse it. As a result, your engine works as well as it can, and an engine that functions at its best lasts longer.

Radiators don't last indefinitely, though. Sometimes, they just go bad. When this happens, other problems, like car heating and air conditioning system malfunctions and even engine failure, follow. Luckily, the symptoms of a bad radiator are easy to spot. Look for:

• Strange engine noises
• Fin damage
• Antifreeze that's turned to sludge
• A sweet, syrupy smell (ethylene glycol -- this usually means you've got an antifreeze leak)

If the needle or digital display for your vehicle's temperature sensor reads hot, though, it can mean radiator failure. Do a careful inspection to determine exactly what's happening.
