Radiator and Cooling System Diagnostics & Replacement Hamilton

Why is Radiator / Cooling System Health Important?

The health of your radiator and cooling system is vital to the long-term health of your engine. Your cooling system consists of a number of core parts including:

  • Engine radiator
  • Radiator cap
  • Coolant (water) and antifreeze
  • Coolant temperature sensors
  • Frost plugs
  • Rubber hoses
  • Heater assembly
  • Engine thermostat
  • Water pump
  • Drive belts

Deterioration or damage to anyone of these critical parts and systems could cause your engine to underperform, causing excessive fuel consumption and emissions. It could also cause damage to key exhaust components such as the expensive catalytic converter and worse of all could destroy your engine through overheating.

Booked the ol' Fuga in for a service this week. I dropped it off early to take advantage of the free clean and asked if I could have it ready at 3 pm. The service went well and they... pointed out things that would need attention in the future. I like the introduction of the vehicle service and repair log book. Which has all my previous services and fix ups recorded in it. And the Fuga was freshly cleaned and ready at 3pm, like they said. Thanks Team
