    Why does my car start sometimes and sometimes it doesn't? We came off the golf course and it wouldn't start.
    It just made a clicking noise, like the battery was dead. It started with a jump. I have had this problem for a few months now. Sometimes it starts and sometimes it doesn't. I tried to start my car a couple of days ago and it wouldn't. I went out today and it ...

    The AC Compressor just went out and needs to be replaced. My quote is $520 for parts $230 for labor. Is that good?
    My 2009 BMW 328I has about 50,000 miles on it, so not a whole lot. Is it common for things like this to happen after 50,000 miles?

      Don't just replace the malfunctioning component. Professional system repair may involve the flushing and replacement of additional parts and fresh lubricant to put it back in proper operating condition. For example if you open the system to replace the compressor, the system should be flushed, all o-rings and seals replaced as well as the receiver drier, orifice tube, and accumulator.

      Without other quotes to compare with for the same work: parts and labor - cannot determine if cost is high or not. It sounds high - but considering the parts (air compressor and kit) alone are only around $344.00 for your vehicle (sources;www.RockAuto.com, www.partsgeek.com).

      You'll need to obtain at least one or two more estimates for the same work - to determine the validity and accuracy of the prices quoted.

      This cost is really too much... I would advise you to fix it yourself if possible. At least it will save your labor cost that is worth $230 according to you. There are seamless videos and tutorials available on net those you can prefer for convenience. To save money on part you can refer any aftermarket dealer i.e. http://www.iautobodyparts.com/.../...nser-details.html because they sell same quality stuffs at reasonable price.

      I disagree with fixing yourself & agree with Jimm

      You need A/C System as well as Automotive Knowledge to
      work on any vehicle

      As Jimm said a failed compressor will possibly put debris in the system
      & it is not a job you can do yourself

      You need professional tools & equipment

      That job properly done could easily go $1,000
      or more on a BMW especially if you go to a dealer
      than double that

      You can perform the work yourself to save some labor cost. Have the a/c system properly discharged, then remove the old components. Reference a good repair manual, or this website; www.autozone.com for details.

    How do I find the Auto Shop versus DIY cost feature on AutoMD?
    When I go to "estimate cost," AutoMD brings up the estimates from Auto Shops in the area. I am looking for the feature that compares the cost for repair between the dealership, auto shops and DIY.

      Try the insta-quotes feature. The DIY cost may not be included as there are no labor costs - only parts cost - if you repair it yourself.

      Loss of coolant because of a coolant leak is probably the most common cause of engine overheating. Possible leak points include hoses, the radiator, heater core, water pump, thermostat housing, head gasket, freeze plugs, automatic transmission oil cooler, cylinder head(s) and block.

      Make a careful visual inspection of the entire cooling system, and then PRESSURE TEST the cooling system and radiator cap. A pressure test will reveal internal leaks such as seepage past the head gasket as well as cracks in the head or block. A good system should hold 12 to 15 psi for 15 minutes or more with no loss in pressure. If it leaks pressure, there is an internal coolant leak (most likely a bad head gasket but possibly also a cracked cylinder or engine block).

      It is important to pressure test the radiator cap, too, because a weak cap (or one with too low a pressure rating.

      1. 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.

      2. 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 usually near or on the thermostat housing.

      I took it to get an oil change and the light was still on. They even cleaned out the bad/old oil. Then while driving the coolant exploded and then the car overheated again..

    Power steering fluid leak
    181,000 miles. Appears to be from the base of the reservoir and is leaking onto the unit below (alternator?) and causing a bad smell. Dangerous?
     
    • Jimm
      3/7/2015 Jimm
      Not dangerous - simply replace the leaking pump. Check these various on-line vendors; www.autopartswarehouse.com, www.RockAuto.com, www.partsgeek.com, to list only a few.
      The power steering pump cost is around $60.00 (remanufactured, minus core exchange) for your vehicle.

    The hose on the right top of the radiator pop out as soon as the temp starts raising. Soon after the car overheat. What is the cause? It seems to me the connection is loose.

      Is the radiator neck in good shape? It should definitely stick out far enough so the radiator hose can slide on far enough for the hose clamp to get a VERY good bite on it. If it's not long enough for that, it's busted and the radiator needs to be replaced.

      Coolant leaking from the left-hand side of the radiator on the M60 M62 engines is very often due to a cracked radiator top-hose stem. The radiators on the E31, E32 and pre-facelift E38's and E39's become brittle and often crack under the top hose.

      You may have a restricted radiator, the coolant is flowing if the upper hose is getting hot, the fan comes on at the right temp.

      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. Rent for free with a deposit from an auto parts chain store like pep boys or auto zone a cooling system pressure tester.

      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 temperature switch
      Faulty water pump
      Faulty / worn serpentine drive belt
      Faulty / worn drive belt tensioner
      Faulty cooling fan sensor or switch

      Overheating with A/C on, or very high temperature only.
      1. Check that the auxiliary fan is working properly
      2. Check the fan clutch.
