The spark plugs and coil packs in a DB9 are snugly tucked away under a Spark Plug Cover. If you’ve had the cover off to perhaps change your Coil Packs and Spark Plugs (as I have been doing as part of dealing with a Lumpy Idle issue), you’ll inevitably need to reinstall the cover. Doing this isn’t hard, but there are a few tips I will share below to get it done just right. Continue reading “Installing the Spark Plug Covers on an Aston Martin DB9”
You may be installing Coil Packs into your DB9 as part of a scheduled service or as part of some other service issue. I am swapping mine out as part of solving a Lumpy Idle issue (check out my post on this). Regardless of the reason, getting it done right is important. In this post I will cover preparing the coil packs plus how to install them properly. Continue reading “Preparing and Installing the Coil Packs into an Aston Martin DB9”
You may be installing new spark plugs into your DB9 as part of a scheduled service or as part of some other service issue. I am swapping mine out as part of solving a Lumpy Idle issue (check out my post on this). Regardless of the reason, getting it done right is important. In this post I will cover preparing the plugs plus how to install them properly. Continue reading “Preparing and Installing the Spark Plugs into an Aston Martin DB9”
You may need to remove the Spark Plugs from your DB9 to replace them at a scheduled service interval or as part of some other service procedure (like doing a compression test or removing the valve cover, etc.). This is a fairly simple procedure once you have all the preliminaries out of the way, but there are a few small tricks to it I will share with you below. Continue reading “Removing the Spark Plugs from an Aston Martin DB9”
Each cylinder in your DB9 V12 engine has its own individual coil pack installed on top of the spark plug right down in the valve cover area. You might need to remove the coil packs to replace them, or service the spark plugs, or to remove the valve cover or something deeper in the engine. I’m replacing mine since my car is suffering from a Lumpy Idle (see my post on this). Removing them is pretty easy once you have the preliminary work necessary to access them out of the way. Continue reading “Removing the Coil Packs from an Aston Martin DB9”
The Spark Plug Covers on a DB9 are used to shield both the Coil Packs and the Spark Plugs inside the valve cover. All this is situated underneath the intake manifolds, so it’s a bit of a phaff to get to them. You may need to remove the covers in order to change the Coil Packs or Spark plugs (like I am) or perhaps you are fixing a leaking valve cover gasket or something deeper in the engine. Either way, it’s a pretty simple process. Continue reading “Removing the Spark Plug Covers from an Aston Martin DB9”
The intake manifolds in a DB9 are big and beautiful, blanketing most of the engine bay, so access to anything underneath usually requires removing them. Some of the reasons you’d need to remove them include changing your Coil Packs and Spark Plugs (as I am doing at the moment). In this post I am covering the actual final steps of unbolting the manifolds (which is a bitch of a challenge), sharing some tips on how to finagle them out of the tight spaces without breaking off the sensors, and unhooking the unseen vacuum hoses. Continue reading “Removing the Intake Manifolds from an Aston Martin DB9”
You might need to remove the Intake Manifolds from your DB9 for many service reasons including the need to change your Coil Packs and Spark Plugs. The process of removing them is fairly involved, and requires disconnecting a crapload of auxiliary items before you can actually remove them. In this article I will cover what defines a crapload. Continue reading “Preparing the Intake Manifolds for Removal from an Aston Martin DB9”
You might be needing to disconnect the fuel rails to change one or more fuel injectors, or perhaps to dig further into the engine removing the Intake Manifolds as part of changing your Coil Packs, Spark Plugs or perhaps your PCV Valves. It’s not a difficult task once you have the prerequisites listed below out of the way.
Note: I will be explaining how to unmount the fuel rails and disconnect them from the fuel injectors, but NOT how to completely remove the fuel rail. God help you if you need to actually remove the rails entirely. At the very bottom of this article I will regurgitate the instructions from the Aston Martin Workshop Manual, but I can tell you know it’s probably impossible to do this with the engine in the car. I bought the special tools and was going to try but waved off after seeing mission impossible in front of me. I found it was totally unnecessary for the service tasks I noted above. We can make do with them loose and able to swing side to side. Continue reading “Disconnecting the Fuel Rails and Removing Fuel Injectors from an Aston Martin DB9”
The Centerpiece under the hood of any DB9 is the 6.0 V12 Aston Martin emblazoned logo on the Intake Manifold Center Brace. You may need to remove this brace for various service items like changing your coil packs and spark plugs or perhaps servicing your PCV valves or something in the fuel injection system.
