2.5L (Duratec V6) - Ghia / ST220 performance
Petrol
During low-speed maneuvers, listen carefully for clunking noises from the suspension; it is common for the rear subframe bushes and front control arm bushings to show signs of wear in Mk3 Mondeos.
While accelerating in a higher gear, watch the tachometer for any 'fluttering' or hesitation; the Duratec V6 can sometimes develop issues with the Intake Manifold Runner Control (IMRC) module or vacuum leaks.
Before starting the engine, check the coolant reservoir for any signs of oil contamination; while not universal, it is worth monitoring the oil cooler seals for integrity given the age of the vehicle.
When stationary, cycle through the climate control settings; the blend door actuators are known to become sticky over time, which can occasionally lead to erratic cabin temperature control.
Usually the time to evaluate the state of the cooling system components, specifically checking hoses and the radiator for brittle plastics.
Consider assessing the health of the alternator and starter motor, as high-mileage examples may eventually require a refresh of these electrical units.
A sensible time to inspect the condition of the suspension dampers and springs, as they will likely have performed their duty well beyond their original design life.
Prioritise regular engine oil and filter changes every 10,000km to keep the Duratec V6 internals clean.
Keep an eye on the spark plugs and ignition coils, as these are vital for maintaining that smooth V6 power delivery.
Flush the brake fluid every two years to ensure the pedal feel stays firm and responsive.
Ensure the transmission fluid is checked or changed occasionally, especially if you have the automatic gearbox, to promote longevity.
Regularly clean the drain scuttles under the windscreen to prevent water ingress and keep the cabin interior dry and fresh.
Estimated repair costs if issues arise
The Intake Manifold Runner Control module regulates engine performance at different RPMs. If the car feels sluggish in the mid-range, you might eventually need to budget for a module repair or replacement.
Given the age of these vehicles, the rubber components in the suspension may eventually lose their elasticity. Budgeting for a professional alignment and bushing refresh can significantly improve the ride quality.
Rubber hoses and plastic fittings don't last forever. Planning for a proactive replacement of hoses and the thermostat ensures your V6 stays cool under pressure.
