      Under normal conditions after 9k miles air filter, oil, coolant and all other fluids checked. Look your manual for service intervals stay up to date with this and keep records in your manual . Failure to do this could void your warranty. Your air filters can usually be cleaned with a air hose . I hope this answers your question. [email protected]

    Cranks, but will not start
    Driving to work and car shut off. Everything worked, but no power to the car (meaning radio, lights air blower, etc...all worked) Got it home and ruled out the timing belt pretty quickly, not 100%, but pretty sure. When I turn the key to the "on" position, the fuel ...

      Plug in your own code reader. Buy one from amazon for $20 because relying on others to read your codes for free is overrated. Having the codes checked BEFORE your recent stalling / no start event is like not checking for codes at all. Its like saying that your blood pressure was good two weeks before your heart attack. This is not a sure thing but it is likely, in my opinion, that you have a bad crankshaft position sensor. There may be a fault code stored right this minute that can corroborate that.

    How do I put camshaft timing right?
    I have a new timing belt and I don't know how to put it in time. There are two marks one that says I (Intake) and another that says E (Exhaust) and each one has a mark. I don't know if the marks should look up or down. The Damper timing is all set. But I'm having ...

      Why would you attempt such a job without a repair manual right next to you that would have the same pictorial I am sending you a link to? The picture says it all really, can't really add anything useful. Good luck

      i am having this same issue, any help you have gotten so far would be awesome. i narrowed it down to a problem with the fuel pump, the pump itself is good, but not getting power. good relay. when we "jump" the relay port and switch the kety to "on", i can hear the pump work, but it still does not start, will crank just fine.

      Have to check for spark and fuel. It could be a fuel delivery problem (fuel pump) or an ignition problem. Do you have any trouble codes?

      we checked for spark, and spark was there. sprayed carb stuff into the air intake(?) nothing happened. as i said, we can hear the pump turn on when we bypass the relay using a wire connected to two points in the relay port. (pos and neg ?)

      I did have an issue with the knock sensor recently, I heard a knock and changed my oil, the knock went away and the check engine light was on, took it to auto zone and they guy said, "you need a new knock sensor" I figured that since i heard a knock, the sensor simply did its job, so i did not buy one, the check engine light went off and car has been fine until yesterday when it died.

      only issue i have is when i turn the key the fuel pump does not engage. When i bypass the relay, it turns on, but will not start. now, i have to figure it out because i have found at least one other person that has done everything i did and they had no answer.

    Why do I have to refill the coolant tank every 3 days?
    There is no leak that is evident from either the tank or hoses. There is also no antifreeze smell either. The van runs in normal temp range even when the tank is dry. A real mystery.

      You have an external leak and you are simply not seeing it. make sure you check the steel tubing that rusts out and leaks that runs from front to the rear heater under the pass side floor under the vehicle. I remember about a year ago getting beat up on an 05 Sedona that was losing coolant and could not find the leak until I accidentally looked under the rear right corner of the vehicle and saw a small coolant puddle on the ground. I replaced the steel tubing, relatively cheap parts at the Kia parts dept. Could even have been fixed using heater hose.

    I have a 2004 Kia Optima that I'm having troubles starting.
    I have to pump the gas to get it started, but once it's running it runs perfect. I'm thinking the gas in the fuel line is draining back into the gas tank when I shut off the car. What do I need to do?

      Best thing would be hooking up a pressure gauge to the fuel rail. Start car and note fuel pressure. Shut off car and watch pressure gauge. Should retain pressure. If not, could be check valve in pump defective
      or bad pressure regulator.

      Usually, the a/c compressor is replaced with other parts. For example if you have opened the system to replace the a/c compressor, the system should be flushed, all o-rings and seals replaced as well as the receiver-drier, orifice tube, and accumulator.

      As a first step - clean all the road dirt and debris from the a/c condensor (just in front of the radiator) using a garden hose spray.

      Someone that knows ac has to look at this with ac gauges attached. Take it back to dealer that did the job and get this fixed under the warranty that I am sure you were given. 1 year / 12000 miles would be typical warranty.

      The engine coolant temperature sensor provides an input voltage to the PCM. As the coolant temperature varies, the sensor resistance changes resulting in a different input voltage to the PCM.
      The engine coolant temperature sensor is also utilized for control of the cooling fan. The issue may be related to; faulty cooling fan switch / temperature sensor, faulty cooling fan relay, faulty cooling fan fuse, faulty cooling fan wiring / connection, faulty cooling fan motor.

      As a first step, check the fuse, relay and wiring for connection and condition. Next, test the fan motor itself by running a jumper wire from the battery positive to the motor - if the motor / fan operates at this point, then you can suspect these items; temperature sensor, wiring, relay, or fuse.

      Auto Zone diagnosed the check engine light with a scanner and found the code P0480. does this help eliminate the problem?
    • Jimm
      6/17/2013 Jimm
      P0480 = Fan 1 control cicuit

      The electric cooling fan is controlled by the powertrain control module (PCM) through the cooling fan relay based on inputs from the following components: - The engine coolant temperature (ECT) sensor - The intake air temperature (IAT) sensor - The A/C selector switch - The A/C refrigerant pressure sensor - The vehicle speed sensor (VSS).
      The PCM controls the cooling fan by grounding the cooling fan control circuit which turns ON the cooling fan relay. The cooling fan relay will be commanded ON when the following conditions are met: - The engine coolant temperature reaches 106°C (223°F) or more. - The A/C clutch requested. - The vehicle speed is less than 38 MPH. The cooling fan relay will be commanded ON regardless of vehicle speed when the following conditions are met: - The engine coolant temperature is 151°C (304°F) or more. - The A/C refrigerant pressure is high. The cooling fan may be commanded ON when the engine is not running under a fan run-on conditions described in the electric cooling fan general description portion of the service manual.


      Possible symptoms of OBD code P0480
      - Engine Light ON (or Service Engine Soon Warning Light) - Engine overheating

      Possible causes of OBD code P0480

      - Fan control relay harness - Fan control relay connector - Fan control relay - Cooling Fan 1 The Error code is generally activated on detection of the following conditions: The P0480 code is detected when the PCM detects that the commanded state of the driver and the actual state of the control circuit do not match.

      Possible Solutions

      - Replace the malfunctioning fan control relay 1 - Replace the cooling fan 1

      In almost all cases of P0480 on Kia, the cooling fan control module replacement is the fix.

    My kia car shows the fault code p1166 what this code means?
    car dies out all the time and no power and pressing the gas pedal all the time.
    • Jimm
      6/12/2013 Jimm
      P1166 = Lambda Controller At Limit (Bank 1).

      Error code P1166 is a primary indicator that the ECU/ECM is receiving negative feedback from an O2 sensor or a bad O2 sensor control. Running an Oscilloscope test is actually not a bad idea in this case, and if it proves to be an O2 sensor, it is most likely the one behind the catalytice converter.

      The only other thing that comes to mind that may trigger a P1166 is a leaky air intake system, and that can be solved by doing a simple smoke test before you end up taking the vehicle to the dealership or repair shop. I would definitely recommend doing this first. If it turns out to be a leaking intake, then that will save you a lot of time and money. The reaction that your car is having at this time is typical for a faulty (leaking) air system or faulty O2 sensor.

      There can be several causes:

      ● Air leakage or restriction in intake or exhaust system
      ● Dirty engine oil or oil level too high
      ● Front HO2S or MAFS contamination
      ● Fuel system
      ● EVAP system
      ● Faulty sensor signals

    When to replace battery

      Replace the battery if the engine cranking seems slower - delayed almost. Also, if the battery test (cranking amp test and load test) shows a weak cell. Have the battery load / performance tested - for free -at any local auto parts stores; Advance Auto, Auto Zone, NAPA - to list only a few.

    what is the spark plugs gap for a set of champion # rc10pypb4
    • Jimm
      5/11/2013 Jimm
      The spark plug gap setting should be; 0.044" for these plugs - or for any spark plugs for the same vehicle regardless of the brand; common gap specification of 0.044".
      5/12/2013 grady
      thank you. should they be pre-set to that when i brought them. the gap on them is .040. i was told not to try to adjust gap i could break tip on plugs
    • Jimm
      5/14/2013 Jimm
      Make sure the spark plug gap is adjusted - they should not be installed with the incorrect gap of 0.040".

      Always - repeat always - check the spark plug gap and reset as required to the correct specification - in this case they should be 0.044" for your engine.
      5/15/2013 grady
      ok will do, thanks again.
