not to sound like a noob, but i just put coolant on the coolant tank resevoir 2 days ago and when i checked today, it was below the low mark. I opened the radiator cap and it was full. Is this normal? should i put more coolant inside the tank?

 

your question makes no sense. You put stuff in the overflow bottle, the radiator itself is always full, you dont want air in there.......closed system. The level of coolant in the overflow will vary if the engine is warm or not.

 

How much you have in the tank will vary on if your car is hot or cold.

 

i checked it while it was cold.. so what does it mean if i have low coolant on the tank, which i just filled up 2 days ago?

 

You are talking about the Overflow tank correct, that is what it is an overflow tank, it doesn't need to be full, it doesn't even need to have fluid in it. Just make sure your radiator is full when it is cool. It will fill up if the engine is getting to hot and needs to release pressure.

 

thanks that was the answer i was looking for.

 

Glad I could help
