Plugged radiator?

Do you have a "bra"?(or front nose cover) on the car? That could be a reason. Air has to flow without restriction(or deflextion) thru the radiator from the outside(straight like an arrow). You may also have a fine wire mesh before the rad that has caught a bunch of debris before it hits the rad(bugs, leaves,paper) that would effectively stop air flow to the rad.
Also, when you view the radiator from the front of the car is it clean and in good condition or has the metal fins got all bent up? A high pressure stream of water will bend those "fins". That and touching it with a hose nozzle>just getting in too close<. Air then can't flow between the fins cooling the water tubes in the rad.
If that is clear, then your head gaskets are leaking due to improper torquing down of the heads. Got to replace the gaskets with new and torque down to specs.

What year and mileage?When does it overheat? all the time or just certain conditions? check to make sure the temp gauge on dash is correct by placing a kitchen thermometer in the rad fill neck, start the car and see how high the temp goes...if it levels off around 200 degrees, your temp sensor is bad. Are the cooling fans coming on when it heats up over 200? Could be a bad fan motor or relay. Make sure the lower air dam under the bumper is not broken, bent or missing...it is needed to force air into the radiator when you're driving. Could be a plugged radiator...might need to be flushed.
Just a few tips for you, Paul

You never mentioned when it is over heating. Does it matter if your stopped or moving? If the tempeture is ok while you are moving then I would look at a bad fan or fan relay. If it is over heating while moving then you may have to replace the radiator do to build up in the core. even a radiator that is 30% clogged can reduce your cooling ability up to 60%. You may also need to run some coolant system cleaner through the cooling system to break up any of the desposits that have built up over the years. If you had rust in the system then you need a total and complete back flush to push all of that junk out of the system. the Cooling system cleaner can sometimes unclog radiators however you have to have at least some water passing though the restricted ports of the core. Hope this helps.

Have you had your radiator cleaned (rodded)? This procedure cleans the junk out of the runners that gets built up over time. Once they finish rodding it out, they will pressure test it to make sure there are no leaks. This procedure allows the coolant to flow completely through without getting plugged up. But, it sounds like you have a lot of new stuff... Might want to get a new radiator if it's in your budget.
