SOURCE: 2000 maxima overheating
You have a new radiator and thermostat, so your coolant was flushed. Was the radiator "burped" afterward to get rid of air bubbles? If not, that needs to be done first - it would explain virtually every symptom you're seeing.
Jack up the car so that the radiator cap is elevated. With the coolant topped off, start the car and let it run until it's about 3/4 of the way to overheating. Then shut it down and go have a beer. When it cools off enough to safely open the radiator cap, do so, and any air trapped in the system will bleed out.
What you're doing is circulating the coolant and the air bubbles inside. The bubbles get lodged behind the thermostat and stay there, keeping it from opening (this causes the car to heat up). When you later pop the cap off the radiator, the pressure is vented from the system, the thermostat opens, and the bubbles pass through. They'll work their way to the radiator (since you've got it elevated) and pop out the open cap opening.
Your coolant level will likely drop somewhat after doing this, as the air bubbles will be gone and the space they took up in the system is now available. You may need to add a little more coolant, so top if off (with the car back on the ground) and recap the radiator, fill the overflow to the marked point on the tank, and you're good to go.
Try this if you haven't already, and post back up with your results. If it doesn't solve the problems, we'll take it further.

Hi the car would only need to overheat once to blow the head gasket,, it depends on how hot the engine got and how long you carried on driving it, you can boil the oil crack the cylinder head ect,,, check the oil for water mixing with it (common sign of head gasket failure) the oil goes like a milky colour,, but if you have already checked this then still dont rule the head gasket out,,, it can leak the other way water out of the cylinder head,,, check for any signs of dripping water around the cylinder head, white smoke from exhaust pipe ect,,
But the best way to rule it out would be to get a compression test done this wont cost much and give you a definate answer,, If it is the headgasket it aint expensive to buy the parts its the labour that cost as it aint a small job,,, if you have the manual give it a go yourself and remember you can post on here if you get stuck along the way,,
Hope this helps some

Check under the hood and inspect the valve cover gasket. If it's bad it would explain why you don't see any leaks on the ground because it's probably burning off on the manifold. This ticking you're hearing is a lack of lubrication to the rocker arms. Apart from the valve cover gasket, you should get under the car and inspect the oil pan and oil filter for seepage. Best of luck on your problem.
