Why is it overheating but temperature gauge is not indicating it?


this may be because the is no coolant around the sender unit in the head ( fill the radiator to the cap )
it can be from an air lock in the engine preventing water flow

I have a 2002 chevy blazer it dies when i go to stop and has trouble picking up speed after pushing gas


Could have a vacuum leak , Is the check ENG. light on ? Could need spark plugs, plug wires ,distributor cap . The IAC motors ,idle air control motor passage could be plugged with carbon. Bad mass air flow sensor could do it. Check for critter nests , found that cars that sit for a while , squires and rodents like to make nests under the hood . I have found air boxes full of dog & cat food. They take insulation and make nests. Check the Air Cleaner Restriction Indicator
The air cleaner restriction indicator is located on the intake duct between the air cleaner assembly and the mass air flow (MAF) sensor.
If the area inside of the clear section is green, no air filter service is required. If the area inside the clear section is orange and Change Air Filter appears, replace the air filter.

99 cadillac deville engine overheating an loosing coolent couple times a day.Replaced thermostat, water pump ok, cooling fans on at 217deg.,radiator pressure tested an holding pressure.engine still keeps...


Check to see if you have flow through the entire radiator.If part of the radiator core is cool to the touch when the engine is at operating temp, this indicates restricted radiator flow. If the entire radiator core is not allowing water to flow through, cooling will not be at all efficient. Also a good idea would be to purchase a block tester. available at napa and other reputable parts houses for around thirty dollars. You remove a small amount of coolant, and put the tool in the radiator, or pressure tank opening. If there are any combustable gasses present, i'e' exhaust, this would indicate a head gasket breech, (or maybe worse) and would indicate that it's time to stop looking for a simple problems, and get proffessional help. Good luck to you!

How to change air filter on a 2009 hyundai sonata


Hi there, here are a few steps to help you out:
  • Turn the Sonata off to eliminate the risk of engine backfires while changing the air filter. Leave the car off until the filter has been replaced or there is risk of injury.
  • Lift the hood of the Sonata. Locate the air filter housing unit on the passenger side of the car, in the front corner. Look for a black, plastic cylinder that has an accordion-type hose attached to it that leads to the engine.
  • Remove the air intake hose and air duct from the housing unit. Disconnect the connector for the air-flow sensor from the filter cover. Unclip the clip on the filter cover. Lift the cover off the housing unit.
  • Take out the old filter from the housing unit. Remove any remaining debris out of the air filter unit. Wipe the inner and outer surfaces of the housing unit with a damp cloth.
  • Place the new air filter in the housing unit. Use a K&N air filter, part number 33-2346.
  • Replace the cover on the housing unit and clip it in place. Reattach the air-flow sensor. Put the air intake hose and air duct back in place on the housing unit.
Best of luck....

Engine code in my 1999 mercedesE320 is PO173 what


Hi, both codes indicates a bad Mass Air Flow Sensor..
The airmass meter is a common problem. CRC makes an aerosol "Mass Air Flow Sensor Cleaner" that you can try to use to clean sensor.It is located in the intake hose between the air filter housing and the throttle body.

Take care

I need to know which way does the thermostat go inside the housing to keep it from leaking


The thermostat should have a little tiny arrow stamped on it somewhere to indicate which way the coolant flows. But to help out, the plug shaped part of the stat usually faces the engine block, where it is subjected to the coolant flow, as this plug is heated, the wax inside expands opening the stat up to allow coolant to flow through the hose(s).

My 2000 ford focus has codes p0102 and p0113 whats that and what could it be?


P0102 - Mass Air Flow (MAF) Circuit Low Input
The MAF sensor circuit is monitored by the PCM for low air flow (or voltage) input through the comprehensive component monitor (CCM). If during key ON engine running the air flow (or voltage) changes below a minimum calibrated limit, the test fails. MAF sensor disconnected
MAF circuit open to PCM
VPWR open to MAF sensor
PWR GND open to MAF sensor
MAF RTN circuit open to PCM
MAF circuit shorted to GND
Intake air leak (near MAF sensor)
A closed throttle indication [throttle position (TP) sensor system]
Damaged MAF sensor
Damaged PCM
A MAF V PID (MAF PID) reading less than 0.23 volts (Refer to equivalent grams/second chart in GO to Pinpoint Test DC ) in continuous memory or key ON and engine running indicates a hard fault.
P0113 - Intake Air Temperature (IAT) Circuit High Input Indicates the sensor signal is greater than Self-Test maximum. The IAT sensor maximum is 4.6 volts or -50°C (-58°F). Open circuit in harness
Sensor signal short to power
Damaged sensor
Improper harness connection
Damaged PCM
IAT V PID reading greater than 4.6 volts with key ON and engine OFF or during any engine operating mode indicates a hard fault.

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!!
