OP can check his coolant level and the level should stay relatively the same when that engine is cold or warm. In other words, his coolant level will still be near the L mark even if the engine is warm. And the Owners Manual speaks for itself that you should check the coolant level when the engine is cool, and bring the coolant level to F mark when its near L.Actually, when the engine is cold, the coolant level should be at or just above "L." Remember, the coolant level rises as the engine warms up. When the engine is warm, the level should be at or just below "F."
Id like to add something to ruthrjs comment above. If youve never let the coolant way low in the plastic overflow reservoir, you usually dont need to open the (metal) radiator cap checking the coolant level inside of the radiator unless you have cooling system leak somewhere. Just add fresh FL-22 coolant into the plastic overflow reservoir to the F mark. Make sure the engine is cold when you want to open the (metal) radiator cap checking the coolant level in the radiator. The coolant should always be full reaching to the (metal) radiator cap bottom, or to the small drain hole on the radiator filler neck.My coolant was under the L so i bought some FL22 to top it up.
When i open the metal cap on the left, i noticed the black plastic tube the cap sits on, had coolant to the cap. Is that normal?
Do you usually fill up the coolant on the left metal cap or the right cap where the picture shown by OP?
