Your car’s engine coolant system is responsible for circulating and thermalizing the engine’s coolant. Over time, it may become necessary to replace the engine coolant, but what does that actually involve? In this article, we’ll take a look at the different types of engine coolants and explain which one your car needs.
Why do my car’s engine coolant levels dip?
Your car’s engine coolant level dips when the coolant is lost or when the thermostat opens to let in more air. Your car has a thermostat that senses the temperature inside the engine and opens when it’s at a safe temperature. When the thermostat opens, the engine coolant is lost and the coolant level drops. The engine coolant should be replaced every 3 years or 24,000 miles, whichever comes first.
How to check the engine coolant level in your car
If you’re like most car owners, you probably only think about your car’s engine coolant level when it starts making weird noises or the temperature gauge starts creeping up. But if your car’s engine coolant level falls below the minimum level specified in your owner’s manual, problems can start to accumulate. Here’s how to check your car’s engine coolant level and take appropriate action if it falls below the minimum:
1. Open the hood of your car and locate the thermostat. It will likely be located on top of the engine block near the radiator.
2. Turn off the ignition and remove the key from the ignition.
3. With a flashlight, check to see if there is any water or ice inside the thermostat housing. If there is water or ice inside, replace the thermostat. If there is no water or ice, continue with step 4.
4. Remove the screws that hold down the cooling fan shroud on top of the engine block (2 screws on each side). The fan shroud should come off easily once the screws are removed.
5. Locate and unscrew both of the engine cooler hoses that connect to the fan shroud (1
What to do if the engine coolant level is too low
If your car’s engine coolant level is low, here are a few things to do:
1. Check the coolant level in the radiator. If it’s below the “minimum” line, add coolant. If it still isn’t high enough, you may need to replace the radiator.
2. Check for blown fuses or a short in the wiring. If either of these are the cause, have a professional check them out.
3. Check for leaks at the GAS PUMP (the black rubber contraption on top of the fuel tank). Replace if necessary.
4. Drain and refill the oil and fuel tanks as necessary (this will also add some coolant).
How to refill your car’s engine coolant reservoir
If you’re like most drivers, you probably don’t think about your engine coolant reservoir all that often. But if your car’s cooling system starts to falter, it’s a good idea to check the level and refill it as needed. Here’s how to do it:
1. Park your car in a safe location with the engine off.
2. Open the hood and locate the engine coolant reservoir. It will be either on top of the engine or inside one of the car’s cooling ducts.
3. Remove the cap with a screwdriver or wrench and pour in fresh coolant until the reservoir is full. Replace the cap and tighten it using the screws or bolts that came with it.
4. Start your car and drive for a few minutes to make sure the new coolant is circulating through the system. If everything looks good, replace any evaporated or contaminated coolant with fresh fluid and drive away!
What to do if the engine coolant level is too high
If your car’s engine coolant level is too high, you should first consult your car’s owner’s manual. Most models will require you to replace the engine coolant if the level is more than 3/4 full. If the level is only 1/4 full, you may be able to wait until the level drops below that before replacing the coolant. If the level is extremely high or if your car does not have a manual, you should take it to a mechanic for inspection.
