      Take a picture of that pipe from the cell phone and show it to local auto parts stores, they will search it in their system network and they will help you out.

    Radiator fan not coming on unless AC is on, then it overheats.
    I have a 2002 Honda Accord. Brand new radiator, hoses, and coolant reservoir. Out of no where the radiator fan only comes on when the AC is on and then it overheats. It seems to be normal when the AC is off, only neither of the fans are on.

      1. Above 199" Farenheith . or 90" Celsius., the radiator fan switch triggers the radiator fan motor, check that switch.

      2. There're two cooling fans, the radiator and the AC condenser motors, they both will activate when the AC is turn on. Check to see if they're working in the same time.

      The radiator fan is only working when I turn on the AC. When I turn the AC on and both fans start working, the car starts to overheat.

      Turn on the A/C, the engine will run hotter. Check the radiator fan switch and use the water from the garden hose to clean and remove the debris stuck in the radiator and AC condenser.

      I'm not so car savvy, but there was air in the the air bleed screw. Sorry if that doesn't make much sense.
      6/23/2014 CVO
      Air pockets trapped in the cooling system can cause the engine to overheat. Some cooling systems have air bleed valves built into the system to aid in the removal of air pockets. Advice: For many cooling systems, the method of removing air pockets is to start the engine and allow it to run with the radiator cap off or loose until all the air escapes from the neck of the radiator. For some systems this method is not sufficient, and the manufacturer has installed air bleed valves. It makes sense.

    Bad replacement motor install.
    This is both a procedural "next step" request as much as a diagnosis request. I need some ideas on next steps to take with my mechanic, after he installed a used motor a month ago. The car lags upon accelerating, intermittently. Sometimes it's almost like a stall. ...

      Hmmm.....have you checked out motor/transmission mounts? I know if those go bad that some of the problems you describe can occur. How about the timing belt as well as ignition timing?

    Did my friend get ripped off?
    Hi, my elderly friend had an oil change 1 week ago. Yesterday she found a lake of oil 10 feet long by 1 foot wide under her car. This happened overnight. She took it back to the place that changed the oil and they charged her $450 for a crankshaft seal. My boyfriend ...

      Yeah the problem you're describing is not from a rear crank seal problem. First off, a rear crank seal failure would only allow oil to leak while the engine is running. While the engine is off, the oil drains back down into the pan and no longer rides within the crank bearings. Second, a rear main seal wouldn't typically allow that much oil to leak. I would definitely suspect the drain plug was either not tightened properly, or the drain plug gasket was damaged.
