Running hot 99
Recently change my water pump, thermostat top hose and for the love of god, I’m still running hot. How do I know if I need to change my radiator. That has to be it

Re: Running hot 99
Did you change the thermostat or just the hose, you weren't clear about that. The radiator is 20 years old so you can only imagine how it looks inside.

Re: Running hot 99
Are you sure that the you have burped out all the air from the cooling system? When you did the thermostat, did you look into the engine(cylinder head) to see if it was clogged with rust and 'mud'? A new stat can get clogged if the deposits get stirred up, and giving the engine & radiator a good flushing before final install can help. You may have riled up stuff that was sitting in the bottom of the engine & head, and it is now moving around, or blocking coolant flow through the thermostat.
Immediately after starting, I'd check that the thermostat is working. The upper radiator hose should stay cool(ambient) until the engine & coolant warm up. It should pretty much stay cool, and then, boing, get hot when the stat starts to move and allow coolant flow. If it gets warm slowly, starting right after startup, then the stat may be jammed open a bit, and allow 'some' coolant flow right away, and then NOT allow enough when you are going down the road.
Did you happen to pull the lower radiator hose from the radiator? You may find a bunch of sludge. When you opened the drain pet**** at the bottom of the radiator, did a bunch of sludge ooze out or was it freely flowing coolant? The answer would give an indication of the radiator condition.
If the system was maintained, with 50:50 coolant/water, it should not get really sludged, even after years. If you don't know the history, you might want to consider getting a backflush fitting (Prestone used to sell them) install it into a heater hose, and connect to a garden hose per the instructions, and flush out the engine & radiator. The garden hose flow will be opposite of normal, and will push flushing water out the radiator cap. It will be messy.

Re: Running hot 99
If that is a flare fitting, likely tightening the fitting to the stationary fitting in the tank, HOLDING THE TANK FITTING FROM TURNING AT ALL, should fix things up.
If the fittings were the 'push on' type(which they do not look like), they have internal O-rings that get damaged if they are screwed together or un-screwed for removal, and they'll leak.
Do not allow the torque of tightening any fitting to get applied to the fitting in the radiator or your radiator might need replacing again.
