Without a set of properly functioning Saturn Astra gauges, you would be missing out on all of the vital information that is necessary to tell you how your engine is performing under a variety of conditions. If you're like us, you like to keep an eye out for any warning signs, and the only way to properly do that from the cockpit is to have an accurate set of Saturn Astra gauges. Factory gauges aren't always the most accurate under extreme conditions, so if your ride is modified beyond the basics, we think you should look into a set of aftermarket Saturn Astra gauges.

Gauges are available in both mechanical and electronic versions. A mechanical Saturn Astra gauge is often easier to install, but gauges for stats such as oil and fuel pressure require that a fluid line be teed into the passenger compartment. Electronic Saturn Astra gauges, on the other hand, read signals from sensors installed on your engine. Pricing for Saturn Astra gauges can run all across the board, based on quality of construction and included features. Some gauges simply offer a basic readout, while others include audible warnings and multiple function presets.

Q: What are the different types of gauges available?
A: There are dozens of gauges available which monitor all types of engine performance. Some common ones are air/fuel ratio, oil pressure, oil temperature, coolant temperature, exhaust temperature, fuel pressure and nitrous pressure gauges. Several more are available, so check our product pages to get more details.

Q: Do gauges work on any vehicle?
A: Gauges are universal and can be mounted virtually anywhere in any vehicle. Gauge pods are usually used to house these aftermarket gauges within your vehicle.

Q: How do you install gauges?
A: Some gauges are electrical while some are mechanical. Electrical gauges use sensors that have to be installed, while mechanical gauges rely on hoses for feedback. All gauges must be wired up for lighting within your vehicle.

Q: How do I install a tach in a car that did not come with one? How difficult is it?
A: A tachometer is a great instrument to have in your car. Monitoring your engines RPM will help you shift at the appropriate time to gain the best performance or even better gas mileage. Most aftermarket tachometers only have 3 or 4 wires that need to be connected for operation. A main power wire that gets connected to a 12 volt ignition source, a ground wire, a tach signal wire that connects to the coil or the designated signal wire in your cars wiring diagram, and sometimes a wire to run the light inside the tach for night time use, which can be connected to the same power source as your other dash lights. If your car did not come with a tach, but it was an option for your specific model then there is a good chance the wiring is already in place to run the tachometer. It is best to purchase a factory service manual and carefully study the wiring schematics to determine if the wiring is there or not. The only tools you will need for this wiring job are a pair of wire cutters, a pair of wire strippers, a good pair of wire crimpers, some crimp-on style electrical connectors and a little electrical tape. While this is a pretty simple job, if you are not comfortable using these tools it is best to seek professional help.

If you are trying to install a late model gauge cluster, including a tach, into an older model car that did not have one the process is a little more complicated. You will need the wiring diagrams for both the donor vehicle and the car you are installing the gauge cluster in. You will then have to carefully trace and mark each wire to determine what it is for. Finally you connect the appropriate wires together (temp gauge to temp sender wire etc.) and carefully tape off any wires that are unused. Because modern cars use have varied computer controlled components it is not always possible or compatible to swap gauge clusters so it is important to research the subject for your specific model before taking the plunge.

Q: Why buy gauges?
A: Gauges can give you the warm feeling of knowing that your engine is healthy and warn you when it isn't. The main gauges that help you monitor the health of any high-performance engine would be the basic gauges, such oil pressure, oil temperature and coolant temperature. Aside from that, they give your car that custom race look.
