Hi, i've had problems with my car overheating for a while, i've replaced the hose that connects to the radiator, a new surge tank installed, a new waterpump and thermostat, i've had a radiator flush, I had to replace the intake manifold gaskets, but the problem is that I have to constantly put in antifreeze because the temperature gets hot and the warning light goes on and reaches temperature to about 280, pretty much the max, if you can help me I would so appriciate it, thank you

Theres white smoke in the morning, but not really at any other time when I start it, would that affect the cooling system, my oil is fine, just had it changed.
