2.4L (C24SE) Petrol - DX/LX
Petrol
While idling in neutral, listen closely for a rhythmic 'ticking' or 'tapping' sound coming from the engine bay, as these 2.4L units can develop valve train noise if oil changes were stretched.
Engaging the 4WD system on a gravel or dirt surface; ensure the selector shifts smoothly into 4H and 4L without excessive clunking or 'binding' sensations in the drivetrain.
Pay attention to the gear changes in the automatic transmission (if equipped); shifts should be relatively smooth, and a long pause or 'flare' between gears might suggest the transmission is ready for a service or inspection.
Inspecting the radiator overflow tank and oil filler cap for any signs of 'mayonnaise' or milky residue, which can indicate the head gasket has been under pressure at some point in the car's life.
This is a key time to verify the cooling system health; consider replacing the thermostat and coolant hoses if they show signs of age or brittleness.
The suspension components, specifically bushings and shocks, have likely served their time and may feel 'tired' compared to when the vehicle was new.
Ensure you check the service records for timing belt replacement; this engine typically requires a belt change every 100,000km to avoid significant engine damage.
Stick to a strict 10,000km engine oil and filter service interval to keep the 2.4L engine happy.
Keep an eye on the power steering fluid levels; these systems can sometimes develop small leaks at the high-pressure hoses as the vehicle ages.
Regularly clear out the cabin air intake area of leaves and debris to prevent dampness from entering the ventilation system.
Ensure the chassis has been greased during regular services, especially if the vehicle has been used for towing or light off-roading.
Check the tire pressure regularly, as the Colorado RC performs best with the pressures recommended on the driver-side door placard for fuel economy and safety.
Estimated repair costs if issues arise
If there is no record of this being done, it's wise to plan for this job immediately to protect the engine. Future Budget Planning: Set aside funds to have a professional replace the belt, tensioner, and water pump for peace of mind.
After years of hauling or daily driving, the ride quality may diminish. Future Budget Planning: You might eventually need to budget for a complete shock absorber and bush kit to restore that smooth 'ute' ride.
Old plastic radiators can become brittle. Future Budget Planning: Should the radiator show signs of weeping or plastic discolouration, it's common to replace it along with the water pump to prevent overheating.
