coolent problem, radiator is dried
recently my car has been running hotter than normal operating temperature, so i figured i should check my radiator and coolant levels.
so i waited till the next morning for the car to cool down. checked the reservoir, levels seems ok. than i release the rad cap, it was under a lot of pressure, waited for the pressure to escape and checked the rad and there was no coolant.
thinking the rad shouldn't be under pressure when cold, i replaced the rad cap, topped up the radiator (roughly 300ml) and refilled the reservoir.
checking up on the car today, coolant levels in the reservoir is higher than my refill, and the radiator is dry, checking from the filler neck.
i don't think the rad should be dry when cold, but can anyone shine some light on this?
thanks

either that or you have a horrible leak, but its going somewhere. fill up the rad..turn on the car look for bubbles coming form the coolant and white smoke from your exhaust. You will know than if not perform a leakdown and that will let you know aswell.

Sounds like a rad cap issue but you already changed the cap. You sure you got the right cap on there?
one of the purposes for the rad cap is to create a vacuum, so if your overflow tank is full and rad is empty chances are there is no vacuum pulling the coolant back in.
Or you can turn the car on, wait for operating temperature and turn the heat on full blast.. then fill the rad up, let it bleed, when no more bubbles come out close the cap. Then check the next day. You probably have a few bubbles or just didnt fill it up all the way.
And to the guys saying headgasket... wtf? lol
