Changing Fuel Filters: Saab 9-3 Tid Guide

Changing the fuel filter on a Saab 9-3 Tid can be a straightforward task. The fuel filter is located near the rear right wheel well, and the process is similar to other Saab models like the 9000, 900, and 9-5. Before beginning, it's important to gather the necessary tools and parts, including a fuel filter kit, socket and ratchet set, and an open-ended spanner set. It is also crucial to prioritize safety by having a fire extinguisher nearby and avoiding smoking or open flames during the process.

Locating the fuel filter

For the 2006 Saab 9-3 1.9TiD, the fuel filter is located on the passenger side of the car, approximately halfway along the length of the car, closer to the rear wheel.

For the early model Saab 9-3 1.9TiD, the fuel filter is located in the engine bay, inside a filter housing on the bulkhead. It is connected to low-pressure fuel lines and has a large ring nut with "ein/auf" and directional arrows.

Some Saab 9-3 models may have the fuel filter located near the fuel tank, either next to it or in a cavity just forward of the offside rear wheel.

It is important to consult a repair manual or a trusted mechanic if you are unsure about the location of the fuel filter in your specific Saab 9-3 TiD model.

Removing the stone guard

To remove the stone guard from your Saab 9-5, first locate the fuel filter. It should be right in front of the rear right wheel well.

Now, remove the stone guard that is protecting the fuel filter from debris. This is the stone guard. Once you have removed the stone guard, you will be able to access the fuel filter and bracket.

The bracket is bolted to the car using a 10 mm bolt. You will need to soak the bolt with penetrating oil for at least 24 hours before attempting to remove it. This is because the bolt tends to rust and can be difficult to remove.

Once the bolt has been loosened, you can then remove the stone guard and drop the filter.

Removing the bolts

To remove the bolts, you will need a 25mm wrench, a socket and ratchet set with an extension, and an open-ended spanner set.

First, grip the body of the filter with the 25mm wrench. Place a drip pan under the filter, as some fuel will leak out from the lines. Next, undo the banjo bolts.

Now, remove the 10mm bolt that holds the bracket in place. Drop the filter and clean the banjo bolts with a wire brush to remove any rust.

Finally, test the new seals for fit, and then install the new filter.

Soaking the bolts in penetrating oil

So, you're changing the fuel filter on your Saab 9-3 TiD, and you're worried about getting the bolts off. Well, penetrating oil could be your best friend here. It's certainly a safer option than applying heat, which can be risky if you're not experienced.

First things first: get yourself a good penetrating oil product. There are many on the market, and they are generally considered safer and more effective than heat. You'll want to apply the oil directly to the affected areas, and it's best to let it soak in for a good amount of time—perhaps even overnight.

If the bolts are still stubborn, you could try heating the area around the bolt with a torch, and then applying more penetrating oil. This combination of techniques has proven successful for some people. You could also try tapping the bolt with a hammer while applying some force with a wrench.

Remember, when you're putting the bolts back in, to add some anti-seize to avoid this problem in the future.

Installing the new filter

To install the new filter, follow these steps:

Firstly, ensure the arrow on the new filter is pointing towards the front of the car. Then, mount the new filter into the bracket and connect the banjo bolts. Torque these down to 16 ft/lb or, if you don’t have a torque wrench, tighten them until they are snug.

Next, put the splash guard back in place.

Now, refill the new filter with fresh fuel before fitting it. Lubricate the rubber seal with diesel to ensure it seals properly.

Finally, start the car. It should start without missing a beat.
