Consult your owner’s manual or a qualified mechanic to determine the correct type of coolant.
To add coolant, open the coolant reservoir cap located on top. Be cautious as the coolant may be hot, so allow the engine to cool down before attempting to open the cap. Add coolant to the reservoir until it reaches between the “MIN” and “MAX” lines. Do not overfill the reservoir. Once the coolant level is satisfactory, replace the cap securely. Run the engine for a few minutes to circulate the coolant throughout the system and check for any leaks. Regular monitoring of coolant levels is key to avoiding potential engine problems and ensuring the smooth operation of your 2015 Buick Encore or Chevy.
Identifying the Coolant Reservoir
To locate the coolant reservoir in your 2015 Buick Encore, it’s crucial to pop open the hood and scrutinize the engine bay. Look for a translucent plastic tank with markings indicating “coolant” or “antifreeze.” It’s usually situated near the firewall (the panel separating the engine from the passenger compartment) and may have a black cap. If you have trouble finding the reservoir, consult your owner’s manual for specific instructions.
Here’s a detailed breakdown to help you identify the coolant reservoir:
- Check the firewall: Start by inspecting the compartment where the engine meets the interior of the car. Locate the firewall, which is a metal or plastic partition.
- Scan for a translucent tank: Look for a reservoir made of clear or semi-transparent plastic. This container typically houses the coolant.
- Read the markings: Most reservoirs are labeled “coolant,” “antifreeze,” or contain some variation of these terms. If you see such markings, you’re likely dealing with the coolant reservoir.
- Check the cap color: Often, the cap of the coolant reservoir is black or a contrasting color to stand out. This visual cue makes it easier to distinguish the coolant reservoir from other fluid containers.

| Prestone Dex-Cool Extended Life Antifreeze/Coolant | G12 |
Opening the Coolant Reservoir Cap
Before you start, park your Buick Encore on a level surface and allow the engine to cool down completely. The coolant system is pressurized, so opening the cap while the engine is hot can result in a spray of hot coolant.
The coolant reservoir is located on the driver’s side of the engine compartment, near the firewall. It’s a clear or translucent plastic container with a black cap.
To open the coolant reservoir cap, follow these steps:
1. Locate the coolant reservoir cap.
2. Place a rag or towel over the cap to protect your hand from hot coolant.
3. Press down on the cap and turn it counterclockwise to loosen it.
4. Slowly lift the cap off the reservoir, being careful not to spill any coolant.
Once the cap is off, you can check the coolant level. The coolant should be between the “MIN” and “MAX” marks on the side of the reservoir.
If the coolant level is low, add a 50/50 mixture of coolant and water to the reservoir. Do not overfill the reservoir, as this can cause the coolant to overflow when the engine is running.
Once you have added coolant, replace the cap by pressing down on it and turning it clockwise to tighten it.
Here are some additional tips for opening the coolant reservoir cap:
| Tip | Description |
|---|---|
| Use a rag or towel to protect your hand. | The coolant system is pressurized, so opening the cap while the engine is hot can result in a spray of hot coolant. |
| Open the cap slowly. | Opening the cap too quickly can cause the coolant to spray out. |
| Check the coolant level. | The coolant level should be between the “MIN” and “MAX” marks on the side of the reservoir. |
| Add coolant if necessary. | If the coolant level is low, add a 50/50 mixture of coolant and water to the reservoir. |
| Replace the cap. | Press down on the cap and turn it clockwise to tighten it. |
Adding the Coolant
With your engine cool, locate the coolant reservoir. It’s typically a translucent plastic container with a black cap. The coolant level should be between the “MIN” and “MAX” marks on the reservoir.
If the coolant level is low, add a 50/50 mixture of antifreeze and water to the reservoir. You can purchase pre-mixed coolant at most auto parts stores.
Once you’ve added coolant, check for leaks. Start the engine and let it idle for a few minutes. Then, look under the vehicle for any leaks. If you see any leaks, stop the engine and have the vehicle towed to a mechanic.
Caution: Do not open the coolant reservoir when the engine is hot. The coolant is under pressure and can spray out if the cap is removed.
Here are some additional tips for adding coolant to your Buick Encore:
- Use only coolant that is approved for use in your vehicle.
- Do not overfill the coolant reservoir.
- Check the coolant level regularly, especially before long trips.
- If you have any questions about adding coolant to your vehicle, consult the owner’s manual or a qualified mechanic.
