I have a 2002 pt cruiser. I had a used motor installed in it and less than 2000 it starts over heating. After changing the thermostat I was told that the head gasket was blown. I had the same shop that put the motor in to replace the head gaskets and put in a new radiator. The car ran ok without overheating for about a week, then I could hear the coolant bubbling in the reservoir. I had the coolant system checked for air. 2 weeks later the car ran hot but the gague mostly stays in middle. It finall

you are better off just getting a decent used motor from the wrecker that will bolt right in with less headaches

sounds like an air pocket in your cooling system need to bleed system and add missing coolant

Easy, your thermostat needs replacing! its an easy job, download manufacturers manual from your computer1

The thermostat housing is the part ton the engine that the upper hose is attar he'd to. Remove the housing and the thermostat will be behind it. A t10mm socket is usually all you need.

The only years that fit your engine are 2001 and 2002. They are correct, the 06 engine will not fit correctly.

thermostat,fans,bad water pump

follow the hose that comes from the top of the radiator to the motor, disconnect the hose and the housing,then the thermostat

Flush rad & change coolant & thermostat. Check operation of rad fan, & make sure it is coming on when engine reaches normal operating temperature. Be sure to bleed air out good when refilling rad/cooling system. Start engine & turn heater on when refilling & let rad fan come on & off at least 2 or 3 times before putting cap back on rad, and refill rad as needed as you do this. then fill return bottle to proper level & see what happens.

Hi, i have put together a step by step guide that will help you with this replacement job. Make sure the vehicle is in a cool state before starting this job.


* Drain some coolant into a clean container until the coolant level is below the thermostat housing.
* Remove the upper radiator hose connection from the thermostat housing.
* Loosen the housing bolts and remove the housing.
* Remove the gasket and scrape it carefully from the surface of the housing and the mounting surface on the engine. If the gasket remains on either of the surfaces, there will probably bea coolant leak after reassembly. Some engines use a rubber O-ring to seal a thermostat housing.
* Compare the size of the thermostat to the old one. They are of different sizes, types, and temperature ratings.
* The temperature rating is stamped on the sensing bulb on the bottom of the thermostat. The temperature bulb faces the block.
* When replacing a thermostat, be sure that the thermostat fits into the groove in the block or outlet housing. If the thermostat is installed upside down, the engine will overheat.
* Install the gasket.
* Reinstall the thermostat housing. Refill the system and run the engine or pressure test to check for leaks.
* When the engine has reached operating temperature make sure the thermostat opens.
* You should be able to see coolant circulating within the radiator.
* Another way of checking thermostat operation is to feel the top of the radiator hose or use a thermometer or multimeter with a temperature probe to confirm that the coolant is warming up.
* If the engine is overheating, but the top hose is still cool to the touch, the thermostat is stuck closed and must be replaced.

NOTE
When a paper gasket is used and the recess is in the thermostat housing, it is a good practice to position the thermostat into the recess and glue the gasket to hold it in place. If it falls out of its groove during installation, the outlet housing can be cracked or a coolant leak will result. Before tightening the water outlet housing, try to rock it back and forth to be sure it is flush. Housings are often cracked during this step.

check the battery and make sure it has a fully charge,also check to make sure the start motor pinion is not jammed in the flywheel, and check the coil pack to make sure have spark.also check the crank sensor
