Default coolant leak

Hey guys I just bought an is250 07' awd and i found that my car is heating up after a whole day driving and losing coolant so I have to be filling it up with coolant. I already changed the radiator cap, the thermostat, water pump... what could be causing this?

Thanks in advance for your help

If you're not leaking coolant, then there's only one other way the coolant could disappear...it is being burnt up in the combustion chamber during operation. Which leads me to a blown head gasket. Pull all 6 spark plugs and take pictures of each and number them so you know which cylinder they came from. Hopefully you only have one leaky gasket on one bank of three.

Good luck!
