What is what to do when coolant is low?

When your coolant level is low, it's important to address the issue promptly to prevent overheating and potential engine damage. Here's what you should do:

1. Check the Coolant Level: Let the engine cool completely before opening the radiator cap or coolant reservoir. Locate the coolant reservoir (usually a translucent plastic container) and check the coolant level. It should be between the "minimum" and "maximum" lines. If it's below the minimum, you need to add coolant. Never open the radiator cap when the engine is hot, as the system is pressurized, and you could be scalded by hot coolant.

2. Identify the Coolant Type: Consult your vehicle's owner's manual to determine the correct type of coolant for your car. Using the wrong coolant can cause corrosion and damage to the cooling system. There are typically different colors of coolant (green, yellow, pink, blue, orange). Mixing different types of coolant can also be harmful.

3. Add Coolant: Purchase the correct type of coolant or a premixed coolant/water solution. You can also mix concentrated coolant with distilled water (usually a 50/50 mix). Slowly add the coolant to the reservoir until it reaches the "maximum" line. If adding directly to the radiator, fill it to the base of the filler neck.

4. Check for Leaks: A consistently low coolant level indicates a leak in the cooling system. Inspect the following:

   • Radiator: Look for signs of leaks or damage.
     • Hoses: Check all hoses connected to the radiator and engine for cracks, leaks, or bulges.
     • Water Pump: A leaking water pump can cause coolant loss. Look for drips coming from the water pump area.
     • Heater Core: A leaking heater core can result in a sweet smell inside the car or dampness on the passenger side floor.
     • Head Gasket: If you see white smoke coming from the exhaust or notice a milky substance on the oil dipstick, it could indicate a blown head gasket, allowing coolant to mix with the engine oil.

5. Monitor the Coolant Level: After adding coolant, monitor the level regularly for a few days to ensure the leak hasn't reappeared.

6. Seek Professional Help: If you can't identify the leak or the coolant loss persists, it's best to take your car to a qualified mechanic. They can perform a pressure test to pinpoint the leak and make the necessary repairs. Ignoring a coolant leak can lead to serious engine damage and costly repairs.
