Fantastic engine power and road performance are derived from high-quality components and accessories. Whether you race competitively or just take joy in driving a performance vehicle, the highest quality aftermarket and OEM parts are critical. Your vehicle's GMC K1500 Radiator is necessary to the cooling system as it stores the coolant reserves that are required to flow around the motor. Your Radiator is installed in front of your motor and uses outside air moving through the engine bay to cool down the antifreeze. Generally, the Radiator is constructed from plastic or aluminum and contains the coolant mixture of antifreeze and water that is used to keep the motor cooled off while it is working. Put right behind the vehicle's front grille, Radiators are a key component of the engine cooling system.

What is a radiator?

The radiator is an important component of your truck’s cooling system. It consists of small tubes and fins, working to keep coolant at the right temperature for the engine. The GMC K1500 radiator is located in front of the motor, and just behind the grille. Coolant, a mixture of antifreeze and water, flows through passages in the engine block, preventing overheating by ensuring that the engine stays at the optimal temperature. The coolant picks up heat from the engine, and is transported back to the radiator to be cooled before flowing back to the engine again.

How much does a radiator cost?

While there is no standard price for a GMC K1500 radiator, there are several available at PartsGeek.com from around $80 to $125.

What are the signs that a radiator needs to be replaced?

If your vehicle’s radiator stops functioning, it won’t take long for the engine to overheat. There are several indications that the radiator on your GMC K1500 needs to be replaced:

  •     If you notice a fluid leak that is pink, yellow or green in color, and has a sweet smell
  •     If the vehicle is regularly overheating
  •     If the coolant has been contaminated and radiator sludge is present, which would make the coolant appear to be a rusty color
  •     The low coolant light appears on your dash, and you consistently have to refill the coolant tank
