    Why does my alloy rims lose 10-15 psi every 2-3 weeks.
    the low tire light comes on, then I check it with my own tire gauge.

      Air leak; at the rims, at the tire beads. Could be dirt or corrosion on the rims at the seal surface.

    My a/c low side reads 150psi what do I do.
    My air conditioning reads 150 psi with the compressor off. I am afraid that the system is overcharged. I afraid to turn the a/c on with the gauge connect as I afraid it will explode. I know the pressure should be reading from 30-55 psi around 55 degrees Fahrenheit ...

      The system only holds 19 oz. so this is easy to do. Have system evacuated (refrigerant removed) to achieve to correct fill volume.

      The pressure reading at the LO side should be around 25-40 psi with the compressor in the "cycled on" mode (running) and ambient temps in the 80 F plus range. When the compressor cycles on the gauge reading dips, and the low reading in the "compressor on" mode is what you look at. Add R134a refrigerant as needed to get pressures in the stated range.

      25 to 40 psi low side

      155 to 180 psi high side

      If the system is empty add the recommended amount. The pressures above are rough estimates. Pressure readings have many variables that effect them like ambient temp, humidity, restricted refrigerant flow and even low air flow through the condenser.

    Air conditioning might be overcharged
    I bought a 12 oz can of r134a refrigerant because my air conditioning would not get cold and the compressor would not stay on for more than 2 seconds. My low pressure gauge read 10psi so I put about 7oz of the can in the system. Now however the pressure gauge reads ...

    Grease on air filter
    I installed a K&N air filter about a year ago and when I inspected it today it had grease on it. Should I be worried?
     
    • Jimm

      Depends - what is the source of the grease? Are you sure it is grease and not engine oil? At any rate, the filter is cleanable / reuseable.

    Why is one of my tires persistently going flat?
    I have replaced the tires, changed to my winter tires, and each time, the same wheel eventually goes flat. -Temperature doesn't impact it. -Either, it happens over time -It started about 8 months ago -Front passenger side -No warning lights

      You have a dent or crack in your wheel so it can't seal. That or the valve needs to be replaced.

      take the tire off and lean the bead of the tire where it sits against the rim. corrosion usually builds up here and causes it to leak when it becomes uneven.

    Oil under auto while car is standing
    Transmission flushed 2 mos. ago, and oil changed also. Now, there's oil under the car after use when car is off. Also, changed gas cap and still have gas smell in auto with check engine light not always off. What's wrong?
     
    • Jimm
      1/23/2015 Jimm
      First question - is the leaking fluid engine oil or transmission fluid? The answer will determine how the leak is to be found and repaired.

      The check engine light is located on the dash and stays on if the computerized engine control system detects an engine performance or emissions problem.
      Have the check engine light tested / scanned for free - most local auto parts stores do this service for free.
      Then post a reply with the specific code for further assistance.

    I have let my Hyundai sit for 3 months in a warm, dry garage. I am worried about tire spots.
    I have heard that tire spots are a thing of the past. Should a car with factory tires and 8000 miles on them be safe from tire spots after sitting inside a warm, dry garage for 3 months?

      They should be okey

      I run air pressures at or within 4 lbs of the max pressure on
      the Tire Sidewall ---NOT what is in the owners manual or on the door pillar

      Not really a thing of the past but you will be okey

    Top middle brake light works, but lower brake lights do not. Any help?
    All fuses and bulbs changed, even brake switch.

      Do the tail lamps and turn signals work ok? If so, sounds like the ground is ok. Check voltage for lower stop lamps, my info says lite blue wire. Use a test light. If no voltage on that wire with brakes applied, back track the wire till you find voltage. My info shows a couple of connectors for that circuit, but, I don't have location of connectors?

    Need info regarding timing and drive belt replacement
    I brought my car to the dealership for a routine oil change. The service tech told me that the mechanic found a cracked timing belt. The drive belt also supposedly needs replacement. The car has only 36K miles on it. (I don't drive much, obviously!) In the time it ...

      Exactly how did anyone find a cracked timing belt - located inside the engine? The serpentine drive belt for the belt driven accessories is readily visible - and may show cracks / signs of wear. However, small cracks on the drive belt (across the ribs) is not an indication for replacement but is considered as normal wear.

      Check the various on-line vendors; www.autopartswarehouse.com, www.RockAuto.com, www.partsgeek.com, to list only a few. For example, they (RockAuto) list the serpentine drive belt fromaround $2.00 for your vehicle.
      This belt is easy to change - reference the 'How-To-Guides' feature on the AutoMD website.

      Recommend for you to find a different and more trustworthy repair shop. The timing belt replacement interval is 60k miles.

      Forget the fuel injection service. There is rarely a problem with them. As far as the timing belt goes
      they should show you the defective belt. If I were you I would get a second opinion.

      Check the fuel vent hose that routes up close to fill pipe, make sure that hose/pipe isn't clogged. If clogged / plugged - try first cleaning with a length of hanger wire.

      Maybe a problem with evap system? The air in the tank gas to go somewhere when you add gas or it will have to burp back up the fill pipe and that will shut off the gas pump. You could try a different gas pump, see if it helps?

      Where applicable, if there is a vent hose that may run up close to fill pipe, make sure that hose/pipe isn't clogged.

    What caused both of my low beam headlights to suddenly quit working?
    I have checked all my fuse and relays. All of the fuses for the low beam headlights are ok. I even switched relays with other good relays of the same voltage and lights still did not work. MY high beams work fine. I even purchased new higher intensity low ...

      Did you check for voltage and ground, anywhere? Whatever low beam bulb the manufacturer recommends for your vehicle is what I would use, just my opinion.

      How are you with wiring diagrams? Note the fuses, did you check for voltage on the fuse circuit? Use a test light, some fusews are hot all the time, some go hot with the key on.
