Default The coolant level at the extension tank for my Honda civic car?

I have checked my coolant for my honda civic 2002, and I have noticed that the coolant level at the extension tank is below the maximum level and it is only about 2 cm above the minimum level and it has been like that since 6 months (the first time I checked the coolant level) and since that time the coolant level did not decreased, so is it normal to have the coolant level at that level ???

If the coolant was cold, it's normal for the level to be near the minimum mark. It also doesn't need to be near the maximum level when it's hot. You just don't want the tank to be empty. If you must add coolant, make sure you match the type of coolant that's already in the car. Putting in the wrong coolant can lead to problems. Factory coolant is recommended for Hondas. If you use aftermarket coolant make sure to use the correct type for Hondas...there are different types of aftermarket coolant.

To be sure open the radiator cap and check the level.

If the radiator cap is working properly it will suck out the antifreeze from the overflow if it is low. And it spits the excess back to the overflow. This depends on how well the spring is inside. If it is old and warn (compressed) it may not work properly.

The antifreeze level may be full in the radiator but a liitle low if the heater core is not full of antifreeze. To make sure leave the radiator cap on the radiator and turn the heat on on the dash board. This causes the heater core to open up and fill with antifreeze. Let the system cool down until it is safe to open the radiator cap. It will now show if it is low or not.

To be on the safe side atleast fill the overflow to the cold mark. This is the way it should be.
