    Got home and coolant was leaking everywhere beneath the car. How can I fix this?
    I popped the hood and noticed one the hoses appears very corroded so I'm guessing the leak is coming from there and dripping down onto the pan and then the ground. I recently had a full transmission rebuild done and after calling the shop they think it is ...

      The most common cause of overheating is because of an external leak from a water pump or a radiator or heater hose. The way to find the leak is to wait till it is overnight cold and maybe just pour water in and see if the leak is large enough to see it simply leak out from where it has a leak. if you pour in a half gallon or more and you still see no leak its time to pressure check the system.

      Here is a short list of possible causes for overheating;

      Low coolant level
      Leaking coolant
      Improper coolant concentration (not at recommended 50 / 50 mix of anti-freeze and water)
      Clogged radiator hoses
      Clogged heater hoses
      Clogged radiator passages
      Clogged heater core
      Faulty thermostat
      Faulty water pump
      Faulty radiator cooling fans
      Faulty radiator cooling fan switch (coolant temperature sensor)
      Faulty / worn serpentine drive belt
      Faulty / worn drive belt tensioner

    When idle my air conditioner blows cool, but when I accelerate I get warm air?
    No matter the acceleration rate I get warm air. Condenser fine, fully charged, compressor fine, new ac instrument panel, no vacuum leaks I can tell. I've got two mechanics stumped on what the problem and said they would do some research and call me back for a ...

      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.

      Which sensors are you referring to - are these the oxygen sensors? If yes, why go to the trouble and labor to only remove for cleaning (if you could clean them at all?) - since you have already performed the labor to replace them?
      The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
      In fact, they (RockAuto) list the oxygen sensors (O2 sensors) from around $19.00 each (for upstream and downstream) for your vehicle.

      Check the 'How-To-Guides' feature on the AutoMD website for the specific steps to replace the O2 sensors.

    How to replace a waterpump belt
    where is the waterpump belt located

      Disconnect the negative battery cable.
      Place protective covers on each fender.
      Drain the cooling system.
      If equipped with an air pump, remove it as follows:
      Loosen thermactor pump adjusting bolt and remove belt.
      Remove thermactor pump hose clamp located below the thermactor pump.
      Remove the thermactor pump bracket bolts.
      Remove thermactor pump and bracket as an assembly.

      Loosen the water pump idler pulley and remove the belt from the water pump pulley.
      Disconnect the heater hose at the water pump or the water pump inlet tube. Disconnect the water pump inlet tube, if equipped.
      Clean any remaining gasket material that may remain on the engine surface.

      To install:
      Coat the new gasket on both sides with a water resistant sealer and position on the cylinder block.
      Install the water pump retaining bolts and tighten to 15-22 ft. lbs. (20-30 Nm).
      Connect the water pump inlet tube, if equipped.
      Connect the heater hose.
      Install water pump belt on the pulley and adjust the tension. Install thermactor pump and bracket, if equipped.
      Connect the negative battery cable.
      Fill the cooling system. Operate the engine until normal operating temperature is reached. Check for leaks and recheck the coolant level.
      When the entire cooling system is drained, the following procedure should be used to ensure a complete fill and that no air is present in the cooling system.

      Install the engine block drain plug, if removed, and close the draincock. With the engine OFF , add antifreeze to the radiator to a level of 50 percent of the total cooling system capacity. Then add water until it reaches the radiator filler neck seat.
      Install the radiator cap to the first notch to keep spillage to a minimum.
      Start the engine and let it idle until the upper radiator hose is warm. This indicates that the thermostat is open and coolant is flowing through the entire system.
      Carefully remove the radiator cap and top off the radiator with water. Install the cap on the radiator securely.
      Fill the coolant recovery reservoir to the FULL COLD mark with antifreeze, then add water to the FULL HOT mark. This will ensure that a proper mixture is in the coolant recovery bottle.
      Check for leaks at the drain cock and the engine block drain plug.

      So it's getting fuel, how do know? did you check it by doing a fuel pressure test? If the car isn't firing the injectors or spark plugs it very well could be the crankshaft sensor. Also have you checked to see if there are any codes stored into the ECU?

      Is there ignition spark present? You have to check.

      The older cougars had a fuel pump reset switch in the trunk behind the trunk pad on the driver side . If you can't find it look in owner's manual. Might be a possible problem.

    The engine overheats when the a/c is on but cools down when the heat is turned on .
    The a/c will blow cool air for a while but warms as the temperature gauge rises. I added anti-freeze and the problem got better for a while but within a week the same symptoms returned .

    Engine over heats when a/c is on and cools down when I change to heat .
    The a/c starts to blow warmer as the temp rises but cools down when I drive faster . I put in coolant and it seemed to work for a few days but now is have same problem .
