    Timing belt broke when pulling out of driveway
    timing belt broke.can someone help me. 2001 Chrysler PT Cruiser 4 Cyl 2.4L, when lineing up the two camshafts how do i know if they are on the compression stroke? please help. what are the procedures. Thank you,

      Set the crankshaft sprocket at TDC by aligning the sprocket with the arrow on the oil pump housing.
      Set the camshafts timing marks so that the exhaust camshaft sprocket is a 1 / 2 notch below the intake camshaft sprocket.
      Install the timing belt by starting at the crankshaft. Go around the water pump sprocket, idler pulley, camshaft sprockets and the tensioner.
      Move the exhaust camshaft sprocket counterclockwise to align the marks and to remove any slack.
      Insert a 6mm Allen wrench into the tensioner opening on the top plate of the tensioner pulley. Rotate the top plate counterclockwise. The pulley will move against the belt and the tensioner setting notch will start to move clockwise. Continue to move the top plate counterclockwise until the setting notch is aligned with the spring tang. Using the Allen wrench, to prevent the top plate from moving, tighten the tensioner lock bolt to 220 inch lbs. (25 Nm). Make sure the setting notch and spring tang are still aligned after the lock nut is tighten. If not repeat the procedure.
      Remove the wrench from the belt tensioner.
      When repositioning the crankshaft to the TDC position, this must be done during the clockwise rotation movement. If the TDC is missed, rotate a further two full turns until TDC is reached. Do not rotate the crankshaft counterclockwise as this will result in improper tensioner settings.

      Rotate the crankshaft two full revolutions and verify that the TDC marks are properly aligned.
      Check the spring tang is within the tolerance window, if not repeat the previous two steps.
      Install or connect the following:

      Lower timing belt cover and torque the bolts to 50 inch lbs. (6 Nm).
      Upper timing belt cover and torque the bolts to 50 inch lbs. (6 Nm).
      A/C lines at the junction block near the upper timing belt cover, if equipped with a turbocharger
      Right engine support bracket and reposition the power steering pump. Torque the bracket bolts to 45 ft. lbs. (61 Nm).
      Right engine mount through bolt and torque it to 87 ft. lbs. (118 Nm)
      Upper radiator support crossmember
      Torque strut bracket
      Upper torque strut
      A/C lines and pressure switch
      Exhaust system to the manifold
      Crankshaft damper
      Accessory drive belts
      Lower torque strut
      Right splash shield and wheel
      Negative battery cable

      You will need to give more detail than what you have or you will get skipped. Tell the full story, all details, location of knocking, what kind of knocking. make me feel like I am there. Could it be from something other than the engine? Infuse your own opinion here as well.

    My car stop running at the middle of the street it cranks but does not start

      You must try to see if a fault code will set by plugging in a code reader and attempting to start the engine often. After each attempt turn the key all the way off so the computer sees this as another drive cycle. Some codes will only set if fault is seen in two consecutive drive cycles. I am confident that a code will set. Also, when you plug in the code reader; confirm that it is able to establish communication with the vehicle. No communication can mean a bad PCM. This cannot be diagnosed without some data to work with, remember that. You can obtain a code reader from for $20 unless you have one already. Give me codes or something more and I will tell you what to do next. Also, the ignition coil should only have battery voltage to it while you are cranking. If you turn the ignition key to the "on" position, the ignition coil will only have battery voltage show up for two seconds and then it goes away. So I don't know what you mean by ignition coil has no power...

      You have an external leak and a mechanic has to find where the leak is coming from, simple as that. It is not something that is guessed at. Could be a water pump. I don't understand why the mechanic cannot know if it is a bad radiator or not. Experienced mechanics are not unsure in a situation like this.

      Check the coolant reservoir tank and fill if needed. Most modern cars have a plastic reservoir of coolant connected to the top of the radiator. This will allow you to see if your coolant is low.Most modern cars have a plastic reservoir of coolant connected to the top of the radiator. This will allow you to see if your coolant is low.

      Be patient if you can. If the hesitation is that noticeable I am confident a code will set very soon. In the mean time buy MAF sensor cleaner and follow the directions and clean the MAF sensor.

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.

      Possible Causes of Engine Hesitation or Stumble:

      Dirty fuel injectors (cleaning the injectors often fixes this)
      Dirty air filter (change filter)
      Dirty / clogged fuel filter (change filter)
      Bad MAP (manifold absolute pressure) sensor
      Bad TPS (throttle position) sensor
      Bad or dirty MAF (mass airflow) sensor
      Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
      Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
      Bad gasoline (fuel contaminated with water or too much alcohol)

      Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

      Dirty or worn spark plugs
      Bad plug wires
      Weak ignition coil
      Wet plug wires

    What would cause heater problems it has a new thermostat
    200 Chrysler Voyager van with heater problems the thermostat was just replaced and it only releases lukewarm air and that's only sometimes.

      With engine at operating temperature, feel both heater hoses. They should both be hot. If not
      you probably have a clogged heater core. If both hoses are hot, you have a problem with the
      temperature blend door actuator under the dash.

      The check engine light doesn't have to be ON to store a fault code.

      Check the vehicle for fault codes to see if there are any sensors were involved to the malfunction of the engine.

      1.Local auto parts stores such as Autozone ( not in California) or Advance Auto parts will scan and retrieve any diagnostic trouble codes ( dtc ) stored in the powertrain control module for free of charge..

      2. has the code reader for less than $17.83 dollars + shipping
      Autel MaxiScan MS300 CAN Diagnostic Scan Tool for OBDII Vehicles
      3.Re-post the dtc's in here " answer question " for further assistance.

      Note: we need the dtc's to identify the sensor, there are a dozen different sensors to operate the car.

      Visit this site and see all the different sensors.

      Note: for the headlights flickering, this is a symptom of a margin ( or bad ) alternator and the electrical test at local auto parts WILL NOT DETECT as a bad one.

    My starter is spinning but not engaging the flywheel even with a boost. The starter and battery are less than a year old
    Could the snow and salt be causing this?
    • HouseCallAuto

      If you hear the starter motor spinning but no gear to gear engagement then the starter motor is likely junk. The only other cause would be an open circuit where the heavy battery cable connects to the starter which is doubtful because this heavy cable runs direct from the positive battery terminal to the starter.

      You did the right thing to replace the egr valve for the P0404 code. This is a very common repair on this engine. OK, now you have the P0401 which is insufficient EGR flow. Did you erase this P0401 yet and drive the car again and see if it returns?

    My vehicle runs perfectly fine in drive and reverse, but when I get to a stop light and press the brake my car feels... it wants to stall but it never does. When I press the gas to drive it jerks a bit and then it rides fine again. My transmission fluid was about 20% gone so I replaced it. But ultimately, I'm not sure if this is a transmission issue or if there's something ...

      our electronic control module is not receiving data on the idle circuit properly, could be a idle air control valve or maybe the rubber hose between the throttle body intake and the air cleaner has been damaged ,thus bypassing the mass air flow sensor and air sensor. When repairing a transmission sometimes it torques this hose and ruptures it by the act of raising it to work on, but not always, so you will have to investigate further

    Where is the trans. sensor locaded
    ck. engine lt. came on. Code P0340
    • Jimm
      1/11/2014 Jimm
      P0340 = Camshaft Position Sensor Circuit Malfunction

      This indicates that a problem was detected in the camshaft position sensor circuit.
      Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.

      A code P0340 could mean one or more of the following has happened:
      • a wire or connector in the circuit could be grounded/shorted/broken
      • the camshaft position sensor may have failed
      • the PCM may have failed
      • there exists an open circuit
      • the crankshaft position sensor may have failed

      With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
      • Visually inspect all the wiring and connectors in the circuit
      • Check for continuity in the circuit wiring
      • Check the operation (voltage) of the camshaft position sensor
      • Replace the camshaft position sensor as required
      • Check the crankshaft position circuit as well
      • Replace circuit wiring and/or connectors as required
      • Diagnose/replace the PCM as required

      The parts are readily available from these many on-line sources,,,,, - to list only a few possibilities. In fact, they (RockAuto) list the camshaft position sensor from around $30.00 for your vehicle. This would be; Airtex / Wells part # 2R1.

      Cam position sensor replacement steps;
      Open the air cleaner holder by undoing the two snaps, then loosening the air pipe fastener with the screwdriver (or a socket wrench) and gently pushing the hose off. Take out the filter, unplug the little hose on the left hand side (assuming you are leaning over the grille and radiator), and wiggle/pull the air cleaner box up.
      The air cleaner box is not bolted in, but you should take note of how it’s positioned now, because you’ll need to push it back in later. It should pop out with a little muscle/wiggle.

      Don’t be too concerned if there’s a little oil on the bottom of the air cleaner housing. That probably came from the crankcase ventilation system — which is also why you have that little hose that you had to pop out.

      Once you’ve done this, you will see and be able to easily access the camshaft position sensor ... if you don’t have a turbo car. It’s right on the side of the engine near the top and is pretty unmistakable as the only large sensor attached to the engine.

      This is a dealer only fix. Even if someone were to replace the WIN module it would need to be programmed by the dealer's equipment. Call a different dealer if you have another within reasonable driving distance.
