    My vehicle is leaking a clear, lightly viscous fluid and has a hard time defrosting/heating
    After oil change on 2/5/2015, my car started leaking a lightly viscous, clear, non-odor fluid in large quantities. It somewhat evaporates during the day but leaves a ring of evidence on the driveway after it dries. It won't defrost and won't heat unless on full ...

      Most likely a cooling system leak - check the radiator reservoir tank and refill with 50/50 mixture of water and anti-freeze, as needed.

      Perform a cooling system / radiator pressure test when the engine is cold - as a first step to locate the leak.
      Obtain a loaner tool / free radiator pressure tester from the local auto parts stores such as Autozone, O'Reilly, NAPA, Advance Auto, or PepBoys. Follow their instructions and pump it to an adequate air pressure 12 -15 psi or the pressure rating listed on the radiator or reservoir cap. Observe the leaks and perform the repair.
      Note: do not over pressurize beyond the pressure allowed by the radiator cap, then test the radiator cap as well.

    My vehicle is leaking a clear, lightly viscous fluid and has a hard time defrosting / heating.
    After getting my oil changed on 2/5/2015, the car started leaking a large quantity of clear but somewhat viscous fluid - large quantities (first noticed 2/21/2015). It is not engine oil and doesn't smell. It won't defrost in the a.m. and is still at zero heat ...

    Engine Light: Not reaching temp quickly enough
    I have a 2003 Hyundai Sonata v6 GLS with 104,000 miles. I never have any problems with it except each year, during the winter, the check engine light comes on. It's always the same code, that the engine doesn't reach temp quickly enough. This happens after 4 or 5 ...

      make sure you have antifreeze in there instead of water and make sure it is mixed properly or buy 50/50

      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.
      There are literally hundreds of possible codes - so this first step is important to begin any diagnosis.

    Sound just like a bad power steering pump. But, to my suprise after replacing with a new one. It still makes the sound.
    Makes the sound all the time. From time u turn on til u turn it off. Also, doesn't have any trouble steering at all. Everyone says it sounds like powering steer pump but, its apparently not. Replaced it with a brand new one. What could it be?

    Clicking noise under hood
    the noise is present when the car starts and doesn't change while driving. It's a constant sound.

      Noises are difficult if not impossible to diagnose via the internet - for obvious reasons. First step - raise the hood to inspect for the location / source of the sound yourself. Too many possibilities to suggest given the limited detail provided.

    For diagnostic purposes: Is the crank sensor tied in with any other sensors, such as the cam sensors.
    The vehicle will run at times and then quit. No spark. Then for some unknown reason, it will later start again

      The crankshaft position sensor does not share common wiring or connections with the camshaft position sensor. Each sensor has it's own wiring, circuit and connection point.

      However, each sensor provides feedback / information to the Powertrain Control (PCM) or Engine Control (ECM) module - as one common point.

    Haven't changed timing belt at 104000 miles.is this bad?
    Also haven't tuned up, replaced belts, serviced trans.or coolant, is this bad?

      most if not all timing belts i believe should be changed ever 75.000 miles i was told but i have seen them go longer
    • Jimm
      2/17/2015 Jimm
      Could be - best way to find out for sure is keep driving and skip these recommended maintenance items. The probable outcome would be bad - and costly.
      Typically,the timing belt should be changed every 60k miles - as example.

      Follow Jimm recommendations to the letter.

      Timing Component Kit

      Timing Belt Component Kit W/Water Pump TCKWP284 Interference engine application
      Timing Belt Component Kit TCK284 Interference engine application

      Replace the timing belt now or head valves and piston will collide when the timing belt breaks.

      See this link for Interference Engine Application.

    Belt makes noise when damp
    When it is raining or damp under the hood it sounds like a clicking noise as a belt turns. The noise goes away as the car warms.

      Several possibilities; worn / faulty drive belt tensioner, belt misaligned, other belt-driven component worn bearing.

      Have you raised the hood to listen and inspect the source of the noise for yourself?

    WHEN IT RAINS OR DAMP A BELT UNDER HOOD MAKES A CLICKING NOISE BUT GOES AWAY AFTER A WHILE CAR GETS WARMER
    If it is raining or damp a sound is made maybe a belt as it turns then finally goes away a car heats up under the hood. like a click click sound.

      No I am not a good mechanic. I guess I will take it to a service station. I do not
      have a lot of money right now. Thanks though.

    Ratchet head sheared off inside serpentine belt adjuster. How do I get it out?
    I was replacing the alternator, used my 3/8 ratchet to loosen the serpentine belt and the ratchet head snapped off and is now stuck inside the serpentine belt adjuster.

    What would make my car shake, buck, sputter, stall while I'm driving?
    It does all of those things even more when my gas tank is full. As the gas goes down in the tank the problem seems to get better. Also, a diagnosis stated that there was a problem with Cylinder 1.

      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

    My car might die or lose power as I press the clutch in to shift into 1st gear, I'll have to pump the gas to keep the -
    revs up to prevent the car from dieing out.Also in first & 2nd gear the car will bog like it did when I was at the stop, the good thing is that the car is rolling so if it did die I could pop the clutch. Also my check engine light comes on.
