Replaced the 'fan & clutch'? Or replaced the 'fan clutch'?
Fans & clutches came in both forward & reverse rotation, according to the engine belt type. The wrong rotation parts will cause overheating.

But because the overheating began before the parts changes, maybe the radiator (although flushed) is still the problem.

Overheating while sitting still is usually airflow related, overheating while moving is usually water circulation related. Also check timing.

Start the engine... is the fan sucking air from the front grille, through the radiator and across the engine? If so, that is correct.

If it's blowing air from the engine to the outside through the radiator and grille, that's backwards.

A leak-down test will usually show a blown head gasket (which can leak gases into the cooling system, thereby over-pressurizing it and causing it to spew forth readily).

Alot of could post here. Do you have the fan shroud still? I'd also check the fan clutch and be sure you are burping the coolant when adding it.

I would nevertheless do a leak-down test and look for bubbles in the radiator, a chemical-detection of exhaust gasses isn't entirely reliable....
