Symptoms

•Coolant warning light illuminated on the dashboard
•Engine temperature gauge reading higher than normal
•Visible leaks under the vehicle
•Steam or coolant odor from the engine compartment

Diagnostic Steps

1
Ensure the engine is cool before checking the coolant level to prevent burns.
2
Locate the coolant reservoir, typically found near the radiator.
3
Visually inspect the coolant level through the reservoir's translucent side.
4
If necessary, remove the cap of the coolant reservoir to check the level directly.
5
Check for any signs of contamination or color change in the coolant.

Solution

1. Safety Preparation

Tools Required: None
Ensure the engine is completely cool before proceeding to avoid burns.
Wear gloves and safety glasses for protection.

2. Locate the Coolant Reservoir

Open the hood of the vehicle.
Secure the hood with the prop rod if necessary.
Locate the coolant reservoir; it is usually a transparent plastic tank near the radiator.

3. Check Coolant Level

Observe the side of the coolant reservoir for the “Low” and “Full” markings.
If the coolant level is below the “Low” mark, proceed to add coolant.
If the reservoir cap is on, carefully twist it counterclockwise to remove it, ensuring no pressure is released unexpectedly.

4. Add Coolant (if necessary)

Tools Required: Funnel
Use a funnel to pour the appropriate type of coolant (usually a 50/50 mix of antifreeze and water) into the reservoir until it reaches the “Full” mark.
Do not overfill, as expansion can occur when the engine heats up.

5. Replace Reservoir Cap

Ensure the cap is clean and free of debris.
Replace the reservoir cap securely by twisting it clockwise until it clicks into place.
