Overheating problem PT Cruiser

Ok here goes. Car overheating problem. Owned car for two years, my buddy owned it for 4 years before that. No issues, but neither changed radiator fluid. So went ahead, did flush, replaced thermostat. Still overheating. Watched during flush/fill for engine to heat up and watched water flowing correctly in radiator. Car runs fine for first 8 to 10 minutes, with water temp in mid-range as always. then it takes off and overheats. Only way to stop car from boiling over is to turn on heater to full blast. Air is super, super hot. funny thing is, after it heats up, if I return car to slower speeds (under 50) with heater on, car does not over heat.

So question is, does this still suggest bad or poorly working water pump? is it possible for this to be a pin-hole leak in head gasket? Crack in block? Fluid is still green and no apparent oil in fluid, no water in oil as that was recently changed as well. This one is really baffling me! HELP?

first, i would have a leak down test done by a shop to verify head gasket condition. then I would check the radiator for flow.you can do a temp check from one side to the other. the last part would be checking the water pump. have not seen many impeller issues with these.

First, how can this be a duplicate question? this is my first posting on this site. Next, how does one accomplish a temp check from one side to the other on a closed system?

Also, would a cylinder presure tester from AutoZone accomplish the same thing (or similar) as a leak down test?

Its a duplicate question when you post the same question more then once which you did and i posted a response to the other exact same question you posted.Which iam still waiting for a response over on that question.That is why i labeled this one duplicate.Because what happens is people ask the same question on different posted questions sometimes over four times and different moderators answer each of these questions when they can be helping other users who havent gotten an aswer to there question yet.By not labeling these duplicate questions when we find them can be counter productive by wasting resources of our moderators answering the same posted questions over and over again.So please go to your other posted question where i responded to you and had some questions for you myself.Thanks in advance for your understanding.

first, the pressure tester I am referring to is a spoecial on that goes in where the spark plugs are that measures the amount of pressure loss over a period of time.
you need a temp gun that will tell the temp of the radiator. this is done externally.
the tools are available for this at a parts store but it is cheaper to spend 34.99 to have a shop check it. the tools will run you 150-200 bucks.

Saturntech9, any chance you can send me a link to the 'other' question you mentioned? This system only informs me on the single question. I wonder if it somehow got entered twice by mistake. I really would like to view your responses.

Roy, your answers are great. I will call my local shop where a friend of mine works, see what they charge. Hope my shop is as inexpensive as you mention, but I fear they are not. This shop recently replaced a broken wiper arm assembly for my in-laws, at the tune of $300! :(
