how to check and add coolant in Cadillac Escalade T1XX (2021-Present)

Symptoms

• Low coolant warning light illuminated
• Engine temperature gauge reading higher than normal
• Visible coolant leaks under the vehicle
• Steam or vapor emanating from the engine bay
• Poor heater performance

Diagnostic Steps

1. Ensure the engine is cool before checking coolant levels.
2. Locate the coolant reservoir (typically found near the front of the engine bay).
3. Inspect the coolant level in the reservoir; it should be between the "MIN" and "MAX" marks.
4. Check for any visible leaks around hoses and connections.
5. If the level is low, determine the type of coolant specified in the owner's manual.

Solution

1. Preparation

• Gather necessary tools and materials: a clean funnel, the appropriate type of coolant, and gloves.
• Ensure the engine is turned off and has cooled down to prevent burns.

2. Locate the Coolant Reservoir

• Open the hood of the vehicle.
• Identify the coolant reservoir; it is usually a translucent plastic tank with a cap labeled "coolant."

3. Check Coolant Level

• Look at the side of the reservoir to see the coolant level.
• If the level is below the "MIN" mark, you will need to add coolant.

4. Adding Coolant

• Remove the reservoir cap slowly to release any pressure (do not remove if hot).
• Using a funnel, pour the appropriate coolant mixture (typically a 50/50 mix of coolant and distilled water) into the reservoir until it reaches the "MAX" mark.
• Replace the cap securely after adding coolant.

5. Check for Leaks

• Inspect the area around the reservoir and hoses for any signs of leaks or damage.
• Start the engine and let it run for a few minutes; monitor the coolant level and look for leaks.
