Coolant protects your engine by keeping the temperature steady and preventing corrosion inside the system. Over time it wears out, picks up debris, and loses effectiveness. That’s when a coolant flush comes in.
How Often to Flush Coolant
- Most Chrysler, Jeep, Dodge, and Ram vehicles: about every 10 years or 150,000 miles with factory fill
- Older models or those using traditional green coolant: about every 3 to 5 years
- Always check your owner’s manual for the exact schedule
Here in Illinois, our mix of hot summers and freezing winters can take a toll. If you’re putting on a lot of miles in stop-and-go traffic, towing, or running work trucks, it makes sense to check the coolant condition sooner.
What a Coolant Flush Does
- Removes old coolant and rust particles
- Clears out scale and deposits that collect inside the radiator and heater core
- Refills the system with fresh Mopar-approved coolant
- Restores proper freeze and boil-over protection for Illinois weather
This service keeps the system clean and helps prevent overheating or internal corrosion.
A Word About Coolant Additives
You may see “quick fix” coolant additives on the shelf at auto parts stores. We strongly recommend you avoid them. These products often promise leak sealing or better performance, but in reality they can:
- Clog small coolant passages inside the engine block
- Reduce coolant flow through the heater core or radiator
- Create buildup that leads to overheating and expensive repairs
The best protection for your engine is fresh Mopar coolant and a proper flush service, not chemical shortcuts.
Signs It’s Time for a Flush
- Coolant looks rusty, brown, or has floating particles
- The coolant reservoir has sludge or buildup
- Overheating in traffic even though the coolant level is correct
- Heater performance is weak in the winter
What a Coolant Flush Does Not Do
A flush is preventative maintenance, not a repair. A flush won’t fix:
- Leaking hoses or radiator tanks
- Water pump or thermostat failures
- Cracked radiators or engine components
