      It may come apart and you will lose all the belt driven accessories, alternator, A/C, Power Steering and not to mention water pump. Check and re-check the fit and then make sure the crankshaft bolt is torqued properly.
      I'm guessing the balancer outer ring has separated from the rubber...or key in the shaft has rounded out and you need to replace it and the pulley.

      since it is not cold enough outside that the radiator is frozen over, check to see if you are low on antifreeze first. if full, you could have a bad thermostat. when the car is running at NOT (normal operating temperature) with the heater on high... feel the heater hoses. are they cold or warm? if cold then you either low on antifreeze or have a bad thermostat. if warm you could have a blocked heater core. but it really sounds like you are low on antifreeze/coolant.

    Is removal of the alternator easy?
    I'm a DIY on my vehicle's like brakes, oil changes, etc. Now I need to replace the alternator on our Camry. Need to know if it is simple to remove or do you recommend I take it to a dealership or repair shop to do it.

      Have the charging system tested - for free; any local auto parts stores. This is the first step. The charging system performance test includes; the battery, alternator and associated wiring.

      There may be a loose / worn alternator drive belt or belt tensioner, among other possibilities. Check these various on-line vendors; www.autopartswarehouse.com, www.RockAuto.com, www.partsgeek.com, to list only a few. For example, they (RockAuto) list the alternator (remanufactured) from around $95.00 for your vehicle.

    Toyota camry 2013 engine stalled on highway by failed oil filter leak
    dealership just filled oil and given car back. Is it safe to drive this car?

      Not sure - what work was performed by the dealership? Any question of safety or integrity of work would be best answered by the repair shop that performed the work.

      I do not trust them. The ticket said" the vehicle stall out by indication low oil pressure."
      Toyota Camry 2013 does not have automatic shut off by low oil pressure. The running engine can stall out w/o oil only by overheating and possible damage . What steps should be done to check overheating and stall out engine and other car systems?
    • Jimm
      3/24/2015 Jimm
      Here's where to start - contact the dealership to gain a thorough, detailed and written explanation of what is meant by 'the vehicle stalled out by indication of low oil pressure'. Does this mean the engine itself has stalled - as in mechanically?

      Then,the next step would be to have at least two tests performed on the engine to assess if there is any damage; cylinder leak down test, and cylinder compression test.

      These two tests and results will provide the sealing and pumping ability of the engine, and will help determine if any excess bearing wear / piston ring wear has resulted from the loss of engine oil pressure and the overheating conditions.

    Where is the fuel filter?
    Not in the engine compartment. Maybe is part of the fuel pump.

      The fuel filter is just inside the engine bay on the drivers side... near the firewall behind the driver's seat. close to the bottom of the bay.
      It is easier to change if the rear driver wheel was removed... it's just more room to work with.

      1) remove rear driver wheel.
      2) remove intake piping - it is just easier to remove the top banjo bolt on the fuel filter with the intake tube off.
      3) then remove the upper banjo bolt on the fuel filter (14 mm)
      4) then the lower banjo bolt... let the fuel drain a bit, then move the lines away so you can work.
      5) loosen the 10mm bolt on the filter "strap"... it holds the filter in position...
      6) remove the filter, then install the new one... that simple.

      Check these various on-line vendors; www.autopartswarehouse.com, www.RockAuto.com, www.partsgeek.com, to list only a few.
      The fuel filter is priced from around $3.47 for your vehicle - from RockAuto.

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

      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..

      Note: it could be an Idle air control valve.

      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.

      Do not skip this important first step - there are literally hundreds of possible fault codes. Avoid wasting/ throwing money at the problem.

      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
