Top 10 2005 Chrysler 300 Questions & Answers

Its on the passenger side on top behind the motor. its easier to take the black cover off the top of the motor. its a iron pipe running from the egr valve to the cover on top of the motor. disconnect it from the cover. its two bolts holding the egr valve on. unplug the plug thats holding it on and take those two bolts out and bring it out on the passenger side. take the iron pipe off the old egr valve and put it on the new one. no silicone needed. place it back in and bolt it down. its gone be a lil tricky gettin it back in but itll go. after its tighten down put the cover back on the engine. plug all of the sensors back up and make sure all hoses are hooked back in place. make sure u connect the iron pipe back to the cover and be careful with the seal inside the cover cause if u break it it will leak air like the problem i had its not bad as it sounds just take your time. if u see EP BAS when u get thru u probably left a sensor unplugged or an air leak. if that happens hit me back and ill tell u how to fix it

I have a 2006 5.7 Hemi 300C AWD - #4 cylinder started to misfire at idle. Problem just happened without cause on a Sunday morning. Dealership mechanics have exchanges coils, PCM, etc. problem stays with #4 and is sporadic (soemtiem cold idle, sometimes hot). Happened after a new fill of 90 octane gas from Shell (always use this station, never any previous problems). Car is in perfect shape, with only the dealer ever touching it at every req. maintenance schedule. Today they are pulling the head to check for valve issues. SMART troubleshooting trees and TSB's are no help so far. Anyone else with a solution?

I had the same problem with my 05. I couldn't shift out of park. So, I checked brake pedal sensor, and wire linkage and they were fine. I took the center console apart and pulled out the shifter assembly and sure enough the problem was at the assembly. There is a plastic piece. that hooks to a small spring that snapped. I ened up renforcing it with a small clamp hose, and ever since its been functioning fine. I imagine I saved my over $500 bucks of repair cost and also wouldn't be surprize for others to have the same problem.

The taillights are not working on my 300. I replaceed the bulbs, but still no lights come on. Is there a fuse for the taillight?

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!!

First, check the oil level. Make sure the oil is at the proper level. If it's OK, then there maybe an oil pump problem or the oil pressure sending unit problem.
A Mechanic with an oil pressure gauge will be able to determine if the oil pump is working correctly at idle or the oil pressure sensor is bad.

RKE means remote keyless entry. Install a new battery in your key fob and your light will go off. Regards, Joe

In the 2005 Chrysler 300 LX - Owners Manual (page 315 and next) you can find the Fuses Location and Description. Remember that you have several fuse box locations.

Hope this help (remember rated and comment this).

Well, FIRST before anything can be diagnosed or repaired, you need to read the codes again. Code P1270 is not a valid code for a 2005 Chrysler 300. This is a " vehicle-specific" code that applies to FORD vehicles as well as a few MAZDA and BMW vehicles. It has to do with the engine rev limiter system. CHRYSLER does not use this code...At least not anywhere I can find.

Instructions

1. • 1 Ensure that the doors, hood, decklid and rear liftgate are properly closed. The alarm cannot properly arm if any of the doors or other openings are not closed.
     
   • 2 Replace the batteries in the key fob to ensure that the remote is capable of arming the alarm system. If the batteries have been dead for more than a few minutes, the fob will need to be synchronized with the vehicle to function. To synchronize the remote with the car, aim the remote at the vehicle and press the lock or unlock button twice. Next, place the key in the vehicle's ignition and turn the ignition switch to the "On" position. All of the steps must be completed within 30 seconds.
     
   • 
     
   • 3 Verify that the parking lamps flash three times when the system is armed using the remote. Alternatively, verify that the alarm is armed by looking at the alarm indicator on the dash. If the alarm is properly armed, the alarm indicator light should blink.
