Chevrolet Captiva Service & Repair Manual: Radiator, Replace

Replacing the radiator in a 2018 Chevrolet Captiva involves several steps to ensure the cooling system functions properly. First, the vehicle must be parked on a level surface and allowed to cool down completely. Once cooled, the radiator cap is removed to release any pressure in the system.

Next, the coolant is drained by opening the drain valve or removing the lower radiator hose. This step is crucial to prevent spills and ensure safe removal of the radiator. After draining the coolant, the radiator hoses and electrical connectors attached to the radiator are disconnected.

With the hoses and connectors detached, the radiator mounting bolts or brackets are loosened or removed to free the radiator from its position. Care must be taken not to damage other components during this process. Once the radiator is loose, it can be carefully maneuvered out of the engine compartment.

Installing a new radiator in Captiva Sport follows a similar procedure in reverse. The new radiator is positioned and secured with mounting bolts or brackets. The radiator hoses and electrical connectors are reattached, and the coolant is refilled to the appropriate level. Finally, the radiator cap is closed, and the system is checked for leaks and proper operation. Regular maintenance and timely replacement of the radiator are essential for optimal engine cooling and overall vehicle performance.
