100,000 Mile service

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.

Thanks,

William

 

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.

My dealer has a schedule - check out...

thanks for the link.
my wife has a 2002 sl1 and i was wondering the same as far as a good
maint. program.
where abouts in san diego are you?
i grew up in the pt. loma area, now live in north carolina.
thanks again

 

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

 

cool.
i left pt loma in 1983 so its been a while since i had been there

 

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?

 

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
NOx.

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.
