Start by disconnecting the battery cable to check the mechanical cooling fan. Carefully watch out for any leaks, deformities or grease leakage on the fan clutch assembly. Replace it if need be. Test for bearing play rocking the fan back and forth with your hand. After that, connect the battery and start the engine; let it run until it reaches normal operating temperature then turn it off. Check if there is any drag when turning the fan by hand. In case there is no drag, replace the fan clutch. Warm up the engine and see if electric cooling fan comes on. If not, check the fuse and relays. Assess its motor by directly connecting to battery terminals. Replace if necessary. This happens through loosening bolts or hex nuts before removing mechanical fans. Remove both the shroud and fan assemblies. When dealing with electric fans, you should drain system fluids first. Disconnect the electrical wires of the connector together with cooler lines of transmission. Reverse installation steps accordingly while at the same time refilling system fluids.

Start by disconnecting the battery cable from the negative terminal. Inspect the fan clutch assembly for fluid leakage, a deformed bi-metal spring, or grease leakage from the cooling fan bearing. Replace the clutch assembly if any issues are evident.
