V8 Vantage Less-Common Maintenance DIY
This section will cover less-frequent but still common maintenance tasks - things that generally need to be done every 5-10 years.

The thermostat in the V8 Vantage has something of a flawed design. The gasket is molded into it and, once the gasket goes bad, the thermostat has to be replaced. The big issue here is that pieces of the gasket can come loose and get lost into your coolant system, never to be seen again.
I recommend replacing the thermostat as preventative maintenance every 5 years or 50k miles (whichever comes first), at the same time as replacing your coolant. I sell Jaguar thermostats, which are direct replacements at a lower price, and recommend getting a new thermostat housing gasket along with it.
Batteries eventually go bad and need to be replaced. It’s easy to know when a battery in an Aston goes bad because a weak battery will cause a bunch of electrical gremlins. In most cars, replacing the battery is a quick job. Not so much in an Aston.
This DIY guide shows you how to replace the battery in a V8 Vantage. If you want to get a lightweight battery, I offer a kit that drops nearly 30 lbs of weight!
Aston Martin designs the doors of its cars to open at a slight angle. The angle is subtle but has two great benefits: it prevents hitting the door against a curb, and it looks really cool without being obnoxious.
The downside is that the struts that hold the doors up at an angle wear out over time and need to be replaced. I sell the door struts (“door check arms”) on their own, or in a package that includes hood struts and trunk struts.
Like the door struts, the struts that hold up the hood and trunk lid also wear out over time, though generally less often as the doors. The good thing for these is that they’re much easier to replace than the door struts.
Brake rotors wear out as they’re used and eventually need to be replaced. Brake pads like the rotor-friendly Porterfield R4-S will allow the rotors to last longer than the OEM Pagid pads, but a time will eventually come when the rotors need to be replaced.
The front rotors are very easy to do, but the rears are a bit of a pain due to the handbrake calipers.
Mass Air Flow (MAF) sensors measure the amount of air entering your intake system. If the sensors get too dirty or are damaged, they’ll need to be replaced.
