100,000 Mile service

Discussion in 'General Motoring' started by William Koscielny, Nov 25, 2003.

  1. I am at about 110000 miles on my 97 SL1 and I was wondering what kind of
    things I should have checked/replaced/flushed. I bought the car with 85000
    miles on it 2 years ago and have only had oil changes (every 3000) and the
    egr valve replaced. What other types of things should I do. I don't know
    when many things were replaced from the previous owner, I never got the
    service records when I bought the car. Any help appreciated.

    Ask the dealer - they will give you a $$$$ list of things to do.

    Standard maintenance stuff if it has not been done lately:

    Spark plugs, ignition wires, gas filter, air filter, PCV valve, transmission
    filter and fluid change (assuming automatic), engine coolant (depending on
    if 2-year/green or 5-year/orange) front disc brakes (check), rear drum shoes
    (check). Note: There is no timing belt since it is chain driven.

    maint. program.

  6. You're welcome.

    Used to be a lot of Portuguese in Pt. Loma - guess that's changed since the
    fishing fleet left.

    I'm in City Heights (grew up in Kearny Mesa), and bought and service my
    Saturn at Saturn of Kearny Mesa.

    Point Loma is changing a lot since NTC closed. The last dry cleaners that
    had the 40's style sailor artwork on the windows is gone. I meant to get
    some pictures before, but missed the opportunity. And they bulldozed a lot
    of the old place and have built new townhomes and condos there. Check out:

    I've got a QuickTime VR from NTC too - check out:

    I've heard the Carolina's are pretty - green, lush and southern hospitality
    and all that.

    Happy Thanksgiving

  8. Check the maintenance schedule in the owner's manual. Anything that
    is listed that you don't have any history for, and cannot be determined
    from inspection (e.g. tire and brake pad wear), ought to be done so
    that you can start everything from a known date and mileage.

    What's an egr valve?

    Bob Shuman Guest

    Exhaust Gas Recirculation valve: its purpose is to allow exhaust gases to be
    mixed into the fresh intake air supply. This reduces pollution by burning
    any unspent fuel. The valve is generally controlled by an electrical signal
    from the engine computer to a solenoid, but can also be mechanically
    activated (manifold vacuum) on older vehicles. The valve opens or closes
    based on the engine RPM.

    They have a tendency to get "coked up" and stick causing the engine's
    exhaust sensors to report a code 032 EGR error and setting the Service
    Engine Soon light. Since the valve occasionally works, the SES light can be
    intermittent and may not stay lit. The fix is very simple since the valve
    can easily be removed and usually can be cleaned with a small flat blade
    screwdriver, wire brush, and some high temp lubricant. The cost is about $3
    for a replacement EGR gasket.

    Hope this helps.

    Actually, it reduces pollution by lowering the amount of oxygen and
    nitrogen in the fuel mixture going into the cylinders. This reduces

    Thanks, Bob. So basically it's a glorified PCV valve?

    A PCV valves function is to draw gases from the crankcase and burn them
    up to prevent dumping them into the atmosphere. It has a restriction (an
    orifice) to prevent too large a percentage of gases being draw in an any
    one time and it as a check vale function to prevent backfires from
    forcing burring intake tract gases into the sump/valve cover and
    possibly lighting off the gases in the sump. An EGR valve is intended to
    meter exhaust gases into the intake in order to replace some of the
    normal fuel air/mixture with inert gases (inert because they were
    already burned once). This allows for better filling of the cylinder but
    since some percentage of the gases are inert, the overall flame speed
    and peak temperature of the "explosion" during the power stroke are
    reduced. This helps reduce the formation of nitrogen oxides and can
    reduce pre ignition because of the lower peak temperatures and slower
    flame speed. The EGR valve is opened only under certain conditions. In
    modern cars it is usually electronically controlled, although it may use
    engine vacuum to do the actual work of opening and closing the valve.
