Changing The Fuel Filter In A Chevy Colorado Diesel

Changing the fuel filter on a Chevy Colorado Diesel is a straightforward process that can be done at home with basic hand tools. The fuel filter should be replaced between 22,500 and 40,000 miles, or when the vehicle's fuel filter counter indicates it is time. The process involves locating the fuel filter, which is enclosed in a black plastic bracket with two black fuel lines coming out of it, one on each end, draining the fuel from the filter, removing and replacing the filter, and priming the new filter before starting the vehicle. The entire job should take around 10-15 minutes.

Locate the fuel filter

To locate the fuel filter on your Chevy Colorado Diesel, begin by parking your vehicle in a safe, level area and removing the gas cap. This will relieve the fuel pressure in the filter. Next, jack up the rear axle and secure the truck on jack stands. Crawl in front of the gas tank and look for the fuel filter, which is enclosed in a black plastic bracket and has two black fuel lines coming out of it. The fuel filter is located under the driver side of the truck.

Drain the fuel

To drain the fuel when changing the fuel filter on a Chevy Colorado Diesel, follow these steps:

Park your Chevy Colorado in a safe, level area and remove the gas cap. This will relieve the fuel pressure from the fuel filter.

Jack up the rear axle and place jack stands securely under both sides of the axle. Then, lower the vehicle onto the stands.

Crawl in front of the gas tank and locate the fuel filter. It is enclosed in a black plastic bracket and has two black fuel lines coming out of it.

Place a catch pan under the fuel filter. Using a clean rag, compress the plastic clips on the ends of the fuel lines and rotate the lines counterclockwise by a quarter turn. Pull the lines straight off the fuel filter. Do this for both lines.

At this point, you can pull the fuel filter out of the bracket and discard it into the catch pan.

Note: Some Chevy Colorado models have a yellow drain plug on the fuel filter housing. If your vehicle has this, twist the yellow plug to drain the fuel before removing the fuel lines and filter.

Once the fuel filter is removed, you can dispose of the drained fuel appropriately. Be careful not to spill any fuel and avoid open flames or smoking during this process.

Remove the fuel lines

To remove the fuel lines from your Chevy Colorado Diesel, you'll first need to park your vehicle in a safe, level area and remove the gas cap. This will relieve the fuel pressure in the lines. Next, jack up the rear axle and secure the truck on jack stands. Crawl under the vehicle and locate the fuel filter—it's enclosed in a black plastic bracket and has two black fuel lines coming out of it.

Place a catch pan under the fuel filter to catch any spills. Using a clean rag, compress the plastic clips on the ends of the fuel lines and rotate the lines counterclockwise by a quarter turn. Pull the lines straight off the fuel filter, then repeat for the other line. Now, carefully pull the fuel filter out of the bracket and place it in the catch pan.

At this point, you can install a new fuel filter. Ensure that the flow arrow on the new filter is pointing in the correct direction—toward the outlet fuel line on the driver's side. Push the fuel lines onto the new filter tubes until they lock into place, then gently pull on the lines to ensure they are secure. Finally, remove the catch pan and screw the gas cap back on.

Remove and replace the filter

To remove and replace the fuel filter on a Chevy Colorado Diesel, follow these steps:

Park your Chevy Colorado in a safe, level area and remove the gas cap to relieve fuel pressure. Turn off the engine and disconnect the negative battery cable. Place a drain pan under the truck to catch any spilled fuel.

Locate the fuel filter, which is enclosed in a black plastic bracket under the driver's side of the vehicle, with two black fuel lines attached. Compress the plastic clips on the fuel line ends with a clean rag and rotate the lines counterclockwise to detach them. Pull the fuel filter out of the bracket and place it in the drain pan.

Install the new fuel filter, ensuring the flow arrow is pointing towards the outlet fuel line on the driver's side. Push the fuel lines onto the new filter until they lock into place. Check that the lines are secure by carefully pulling on them.

Reconnect the negative battery cable and turn the ignition on and off four times to prime the new fuel filter. Crank the engine on the fifth turn. Check for leaks while the engine is running, then turn it off.

Finally, reset the fuel filter counter on your dashboard.

This process should be done every 22,500 miles or when indicated by the fuel filter counter. It is a straightforward task that can be completed in about 15 minutes with basic hand tools.

Prime the new filter

To prime the new filter, get into the truck and turn the ignition on and off four times. Then, crank the engine on the fifth turn. This will put fuel in the fuel lines and ensure your engine isn't harmed.

After priming the new filter, get out of the truck and inspect the new fuel filter for leaks while the engine is running. Then, turn the engine off.
