hey i got a question... on my reserve of coolant for radiator.. sometimes when i check it the coolant level is on maximum, and again i check it, the coolant is below the maximum (3/4), then when i check it back it goes back to the maximum. do u think i got a problem? maybe the radiator cap? coz when its in maximum level my temp goes high quickly. but not overheating bcoz of the fan.

You do know that anti-freeze is water based and like water expands when cooled and contracts when heated, right?

Aside from that, also take into account, most of the time when it's cool there isn't a whole lot of anti-freeze in the waterjacket, it moves there when it fills up when the waterpump's on.
