Question about 2005 Chrysler PT Cruiser
2002 PT Cruiser comes on at idle only-oil is full and freshly changed.
I would suggest you change the oil pressure switch ,also called oil sending unit first. this part is not that much and isnt hard to do.if that doesnt fix it then you might have an oil pump going out

This is the pressure light, nothing to do with the oil needing to be being changed, you have low oil pressure being indicated, this will destroy the engine if the light is really indicating low oil pressure, have the oil pressure tested with a mechanical test guage at a shop, if the oil pressure is ok then replace the oil pressure light sending unit.

Could be a bad oil pressure switch, or a bad oil pump. Both will cause this issue. Hope it is the switch b/c the oil pump is a costly repair.

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.
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.
