Installing the Front Under Tray on an Aston Martin DB9

Aston Martin Front Under Tray Parts DiagramYou may have had the front under tray off on your DB9 performing your annual service or some other exciting service task.   Eventually it’s time to put it back on.

I found that it’s pretty much the reversal of the removal steps (check out my post on how to remove it), but I did learn a few things along the way when I did it.  You essentially have one really large sheet of aluminum to hold up while you install about 40 bolts.  Challenging to maneuver, and tedious to replace all those bolts.

Checking the Tire Pressures on an Aston Martin DB9

Checking the Tire Pressure on an Aston Martin DB9You might be checking your DB9 tire pressures routinely or even as part of an annual service.  There are some tips I can share with you here.

I’ve used the official Aston Martin Vehicle Inspection Checklist as my guide on what we should be checking.  You can see a copy of it here.

Check out my other posts and videos relating to your tires:

Checking the Tire Pressures

You should check the tire pressures when they are cold (after the car has been sitting for several hours).  Tire temperatures go up under normal driving, and this heat increases the tire pressure (which is normal).   All the specifications are for measuring and adjusting the tires pressures when they are cold.

Inspecting the Tires on an Aston Martin DB9

Checking the Tire Pressure on an Aston Martin DB9You might be inspecting  the tires on your DB9 occasionally or as part of your Annual Service.  Aston Martin wants us to check more than just the tire pressures, and I think that’s a good idea.   We depend on these tires to keep us safe.

Tire Pressure Sensors on an Aston Martin DB9

The DB9 is equipped with a Tire Pressure Monitoring System (TPMS) that includes Tire Pressure Sensors (TPS) mounted to each wheel.  They are an integral part of the air valve.   You’ll notice that each of your air valves has a colored ring around it, either Red, Green, Blue or Yellow.   In your trunk / boot is a mysterious little box with LEDs.  This is the TPMS indicator panel, and if you ever get a warning indication on the dash, you’ll need to check the LED’s and see which color is lit, and that’s the tire with the issue.

Measuring the Tire Tread Depth on an Aston Martin DB9

Measuring the Tire Tread Depth with a Vernier CaliperMeasuring the tire tread depths on your DB9 is part of every annual service.  This isn’t a sexy topic, but it is a very useful one if done correctly.  By measuring and reviewing the data properly, you can actually spot issues with your suspension, tire pressures and wheel balance.

Installing the Front Inner Wheel Well Arch Liner on an Aston Martin DB9

Aston Martin DB9 Front Wheel Arch Liner Parts DIagramYou’ve likely had the Front Inner Wheel Well Arch Liner out on your DB9 to do some service task, most likely Changing the Air Filter as part of your annual service.

Check out my other post and video on how to remove it.

Reinstalling is mostly a matter of reversing the removal steps, but I have a couple of tips that will help you along the way. Continue reading “Installing the Front Inner Wheel Well Arch Liner on an Aston Martin DB9”

Bleeding the Brakes on an Aston Martin DB9

Aston Martin DB9 Front BrakeYou may need to bleed the brakes on your DB9 for several reasons like replacing a caliper, a cracked hose, or as part of changing the brake fluid every year with the annual service (which is what I am doing).

Brake fluid is hygroscopic – which means it absorbs water, even out of the air.  The potential for water in the brake lines is bad mojo, so Aston Martin requires that all the brake fluid is changed as part of every annual service. Continue reading “Bleeding the Brakes on an Aston Martin DB9”

Installing the Rear Under Tray on an Aston Martin DB9

Reinstalling the rear under tray / shield on your DB9 is easy.  I am assuming you’ve already removed it for some other service task (like changing your rear differential fluid), and you can check out my previous post and video on how to remove the rear under tray.

While I had the tray off my car, I took the time to clean it up so it looked good as new.  This was simply using my pressure washer to clean it off (you could use a hose and a scrubby brush equally well), and then after it was dry I treated it to an application of Meguiar’s Ultimate Black Plastic Restorer to make it look as good as new.  Check out the results!

Changing the Rear Differential / Transaxle Fluid and Filter on an Aston Martin DB9

Draining the Rear Differential Oil on an Aston Martin DB9
In the first post I explained how to drain the oil

This is the second part of my post on Changing the Rear Differential / Transaxle Fluid and Filter on a DB9.  You should really check out my previous post and video on draining the rear differential fluid first as this is a continuation of that process (you can find it here).

We left off with the car in the air, rear under tray removed, drain & fill plugs removed, oil drained and filter removed.   Time to get on with putting it back together! Continue reading “Changing the Rear Differential / Transaxle Fluid and Filter on an Aston Martin DB9”

One item that pops up on the DB9 Annual Service requirement periodically is changing the rear differential / transaxle fluid.    To be clear this is NOT the transmission fluid (which in theory never needs changed).  I am covering only the process of draining the fluid in this post, and will cover changing/cleaning the filter and refilling the oil in the next post [I just don’t want the post to be too long].
