Autozone has a repair guide on their site http://www.autozone.com/shopping/repairGuide.htm?pageId=0900c152800c1655
unfortunately, that does not lead to guide.... once there you have to search and then no guide shows up... too bad, needed a good one with pictures, lol... anyone got a good camera, shoot some photos to show me exactly where it is, the one guy makes it seem like a really big deal, sounds like a salesman for dealership lol...
1. Pop the hood and locate the thermostat. It's on the passenger side of the engine and has a plug leading into it.

2. Unplug the thermostat housing from the engine block using the 3/8-inch ratchet and socket set. The housing will come off in your hand and then you can pull out the old thermostat.

3. Scrape off the engine block and the thermostat housing's mounting surfaces with the gasket scraper. This is to ensure the replacement gasket seals correctly.

4. Place the replacement thermostat into the engine block and place the gasket over the ends of the bolts in the thermostat housing to keep them aligned.

5. Bolt the thermostat housing into the engine block using the 3/8-inch ratchet and socket set.

your 3/8 socket is not going to fit that metric bolts and there is no gasket on the housing it is a o-ring on the thermostat that seals that housing
In order to do the job properly, the intake plenum must be removed with the throttle cables, an injector plug and the fuel supply line. The bolts are 10mm and it doesnt matter what drive size the ratchet is, but you will need an extension. Biggest thing to remember is to torque the new housing to specs so as not to snap it. It will take a couple of hours to complete.
There is no thermostat on the PT Crusier, heat is detected by head sensors at two locations on the engine block.
I dont know where you get the idea that there is no thermost yes there is. There is one in the top of the head . Where the upper hose is connected
