The coolant goes into the engine’s expansion (overflow) reservoir, not directly into the radiator. Do not open the system when hot; fill the reservoir to the MAX line with a 50/50 Dex-Cool premixed coolant after confirming the engine is cold.
What to know before you top up
On a 2014 Cruze, the cooling system is topped up through the translucent expansion tank located in the engine bay. The tank has MIN and MAX marks to indicate proper level. Use GM-recommended Dex-Cool (orange) or a compatible 50/50 premixed coolant. Never mix types, and never open the cap when the engine is hot.
Before attempting a top-up, make sure you can safely access the reservoir, have the correct coolant on hand, and are prepared to reseal the system if you notice leaks or other issues.
When you’re ready to top off, follow these steps carefully to ensure a proper fill and avoid damaging the cooling system.
How to top up the coolant
Follow these steps to safely fill the coolant in a 2014 Cruze:
- Park on level ground and let the engine cool completely before touching the cap.
- Locate the coolant expansion tank in the engine bay; identify the MAX and MIN level marks on the side of the tank.
- Clean the area around the cap to prevent dirt from entering the reservoir.
- Carefully remove the cap from the expansion tank when it is cool to the touch.
- Slowly add Dex-Cool 50/50 premixed coolant until the level reaches the MAX line.
- Replace the cap securely on the reservoir and tighten it.
- Start the engine and let it reach operating temperature, then check for leaks and recheck the level when the engine is cold again. Top up if necessary, but do not overfill.
By following these steps, you can safely replenish coolant without risking air pockets or pressure issues in the cooling system.
Additional cautions and maintenance tips
Always use Dex-Cool or a GM-approved coolant and keep to a 50/50 mix unless your manual specifies otherwise. Do not mix coolant types or use plain water alone. If the level repeatedly drops below MIN, there may be a leak or a faulty cap; have the cooling system inspected by a qualified technician.
- Do not open the expansion tank or radiator cap when the engine is hot.
- Use distilled water only if you’re mixing concentrates to achieve the 50/50 ratio.
- Inspect hoses and the reservoir for cracks or leaks during topping up.
- Follow the vehicle’s maintenance schedule for coolant flushes and replacements as advised in the owner's manual.
In short, coolant is added via the expansion tank on a 2014 Chevy Cruze, using the recommended Dex-Cool 50/50 mix, and only when the engine is cold. If you’re unsure or notice persistent leaks, consult a professional.
Summary
The correct place to add coolant on a 2014 Cruze is the translucent expansion/overflow reservoir. Ensure the engine is cold, use a 50/50 Dex-Cool premixed coolant, fill to the MAX line, and reseal the cap firmly. Avoid mixing coolant types, never open hot cooling system components, and seek professional help if you notice leaks or abnormal temps.
