How to Remove a Radiator From a 1997 Chevrolet S-10 Truck

Most people change the oil and air filter in their truck's engine on a regular basis, but they don't change out the coolant with the same frequency. When the coolant is neglected, it eventually will become so contaminated that it causes corrosion on the inside of the radiator, rotting it from the inside out.

Instructions

1

Allow the engine to cool for several hours before working on the cooling system. Place a drain pan under the radiator and open the petcock with your hand to allow the coolant to drain out of the radiator.

2

Loosen the hose clamps on the upper and lower radiator hoses using the pliers or a flathead screwdriver, depending on the type of clamps your truck has. Pull off the hoses and point them toward the drain pan so they can empty out.

3

Remove the overflow hose off the top of the radiator using your hands, then unclip the a/c line clip on the radiator support using your hands.

4

Unbolt the upper and lower fan shroud from the core support with the 3/8-inch ratchet, extension and sockets, then lift them out of the engine compartment. Use the line wrench to disconnect any oil cooler or transmission cooler lines connected to the side of the radiator.

5

Hold the radiator by the side tanks and lift it straight up out of the core support, trying not to tilt it toward the engine so you don't spill additional fluid from the container.
