SOURCE: I have a 2005 Chrysler 300 Touring my engine light

The Chrslyer engines are prone to carbon build up in the engine when they are not driven hard. When the misfire occurs the engine runs rough, the car shakes a bit, and the check engine light comes on. The good news is that this is a recognized issue at Chrslyer. There is a Technical Service Bulletin (TSB) out for this. Synchronicity in the Universe being what it is, my car is in the shop at this moment being serviced for this very same thing. It is a 2002 300M Special Edition with 57,000 miles on it. I haven't been driving it as much because I started taking a commuter train to work and when I do run it, I do not let the engine get up to operating temperature nor do I run it at highway speeds - thus the carbon build up. You may simply need to have the carbon blown out of the engine. Talk to a Chrysler Tech about a TSB for carbon build up leading to intermittent engine misfires and see if this might be at the bottom of the problem.

SOURCE: 2005 Chrysler 300 thermostat location?

Hi,

In your Model :-

The automotive thermostat is a temperature controlled on and off valve. When the temperature rises to a predetermined temperature, the thermostat opens up to allow the engine coolant to flow through the cylinder block and the radiator. This flow is crucial to maintain optimum operating temperature for fuel efficiency, enhanced driveability, and engine protection. The coolant flow is reduced when the engine is cold, and the flow is increased when the engine is hot. Contrary to popular opinion, operating the vehicle without the thermostat doesn't make the engine run cooler. It will actually run hotter because there isn't a thermostat to slow the coolant flow. This means the coolant doesn't stay in the radiator long enough to dissipate its heat.

TO TEST THERMOSTAT

There are several ways to test the opening temperature of a thermostat.
One method does not require that the thermostat be removed from the engine.

  • Remove the radiator pressure cap from a cool radiator and insert a thermometer into the coolant.
  • Start the engine and let it warm up. Watch the thermometer and the surface of the coolant.
  • When the coolant begins to flow, this indicates the thermostat has started to open.
  • The reading on the thermometer indicates the opening temperature of the thermostat.
  • If the engine is cold and coolant circulates, this indicates the thermostat is stuck open and must be replaced.
The other way to test a thermostat is to remove it.
  • Suspend the thermostat completely submerged in a small container of water so it does not touch the bottom.
  • Place a thermometer in the water so it does not touch the container and only measures water temperature.
  • Heat the water.
  • When the thermostat valve barely begins to open, read the thermometer. This is the opening temperature of this particular thermostat.
  • If the valve stays open after the thermostat is removed from the water, the thermostat is defective and must be replaced.
  • Several types of commercial testers are available. When using such a tester, be sure to follow the manufacturer's instructions.
  • Markings on the thermostat normally indicate which end should face toward the radiator. Regardless of the markings, the sensored end must always be installed toward the engine.
  • When replacing the thermostat, also replace the gasket that seals the thermostat in place and is positioned between the water outlet casting and the engine block.

Positioning a thermostat into an engine.
  • Generally, these gaskets are made of a composition fiber material and are die-cut to match the thermostat opening and mounting bolt configuration of the water outlet.
  • Thermostat gaskets generally come with or without an adhesive backing. The adhesive backing of gaskets holds the thermostat securely centered in the mounting flange, leaving both hands of the technician free to align and bolt the thermostat securely in place.

TO REPLACE THERMOSTAT

CAUTION
If the radiator is filled to the top with coolant and the engine is run without the radiator cap in place, the coolant will expand and spill over as the engine warms up.
  • 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.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

SOURCE: Service Engine Light flashes-Chrysler 300

if the light only flashed and went out, you have no reconizable issue. happy motoring. the system will sometimes catch little glitches and no electrical system is flawless. it will catch it and flash. if there was a serious issue the would stay illuminated and codes could then be retrieved. if it gives you piece of mind by all means go see your dealer. just keep an eye on things and always be aware of how your vehicle performs. i wouldnt waste the money until the light is illuminated constantly.

SOURCE: Chrysler 300 3.5 v6 Slight engine knock - oil always changed

I have a 2006 with a 3.5 (41,000 miles). No oil consumption but had the knock. Started as a slight knock and continued to get louder. My buddy works at the dealer and hooked me up. Chrysler knows about this problem, it's the rocker arm assembly coming apart. They have a new revised part to fix the problem. THEY NEED TO RECAL THIS.

Your lifters are knocking most likely. I'm assuming it's the worst when you first start it. Get it checked out by someone who knows cars.

I have top end knock on my 2006 chrysler 300 that comes and gos


There is suppose to be a knock sensor on most of the modern engines. There is also a part in the variable camshaft timing engines that would result in knocks and damage if it let the engine timing advance too far. You need a dealer to check the full range of timing on your motor. Tell them you do not want just a trouble code test, but a timing light used.
