Radiator Service
Care for the fluid in your cooling system.
Radiator service replaces old coolant to help maintain engine temperature. Our team checks the coolant specification required for your vehicle.
Why coolant condition matters
Coolant is part of the system that carries heat away from the engine. Shell’s coolant overview explains the importance of heat transfer, protection against freezing and boiling, and corrosion protection. The suitable formulation depends on the application; ask our team to confirm the coolant required for your vehicle.
Vehicle-specific service
Bring your vehicle details and previous coolant-service history if available. The team can help review the manufacturer’s coolant specification and the service appropriate for your engine. Contact your chosen shop if you want to confirm service availability before visiting.
Concerns that need attention
Pennzoil’s vehicle warning-signs guide notes that a sweet smell can indicate a coolant-related problem. Coolant loss, unusual odors, or overheating should be assessed to identify the cause; scheduled coolant replacement may not resolve an underlying problem.
Recommended maintenance timing
We recommend radiator coolant service every 100,000 miles. Use the coolant specification required by your vehicle manufacturer. If the last service date is unknown, ask our team to help review your records and the next recommended maintenance step.
