Dropping The Oil Pan On A 2004 Jetta: Step-By-Step Guide

If you're looking to drop the oil pan on a 2004 Jetta, you'll first need to drain the oil. This is done by locating the oil drain plug on the backside of the oil pan, which is in front of the front wheels and to the right of the vehicle center line. Place a drain pan underneath, loosen the plug with a wrench, and let the oil drain. You'll then need to remove the oil filter, located on the front side of the engine. Once the oil has drained, you can begin to remove the oil pan. This process involves removing bolts and using a pry bar to separate the pan from the block. It's important to clean the oil pan mounting area and apply a new layer of sealant before installing the new oil pan. Finally, you can refill the oil and run the engine briefly to check for leaks.

Drain the oil

To drain the oil from your 2004 Jetta, you will need to raise and secure the vehicle. Place a jack about 5" back from the front wheel cutout on the long vertical part of the frame. You can jack up both sides of the car, but it is sufficient to just jack up the driver's side. Raise the corner of the car so you can work underneath it, then place a jack stand next to the jack and raise it to its highest notch. Lower the jack so the car rests on the stand.

Next, place an oil drain pan under the oil drain plug, which is located on the backside of the oil pan, in front of the front wheels and to the right of the vehicle centerline. Use a 19 mm box end wrench or socket wrench to loosen the oil drain plug, then loosen it further with your fingers and let it fall into the oil drain pan. Watch for metal flakes in the oil, which could indicate a serious engine problem. Allow the oil to drain until it slows to small drops, then wipe the area around the oil drain with a rag.

Replace the drain plug and tighten it with your fingers. It is better to put a seal under the drain plug (outside diameter 20 mm, inside diameter 15 mm).

Remove the splash shield

To remove the splash shield from a 2004 Jetta, you will need a T25 torx driver, a jack, and jack stands.

First, locate the series of T25 screws on the splash guard underneath the front of your car. Remove these screws. Then, push the two tabs on the splash guard and pull it down.

Now, you can move on to removing the oil pan. To do this, remove the three 16mm bolts on the side of the oil pan. Also, remove the two 5mm Allen bolts that hold the pipe to the oil pan. Next, remove the 10mm bolts from the oil pan using a socket extension and swivel where necessary. Insert two bolts a couple of turns into the oil pan in opposite corners. Separate the oil pan from the block with a pry bar. Remove the two placeholder bolts and then separate the oil pan completely with the pry bar.

Remove the oil pan

To remove the oil pan from a 2004 Jetta, follow these steps:

First, drain the oil. Raise the vehicle, place a drain pan underneath, and remove the drain plug using an 8mm Allen bit. Allow the oil to drain, then insert the drain plug.

Next, remove the splash shield. Take out the T25 bolts and pull the splash shield out.

Now, you can begin to remove the oil pan. Remove the three 16mm bolts on the side of the oil pan. Then, remove the two 5mm Allen bolts holding the pipe to the oil pan. Remove the 10mm bolts from the oil pan using a socket extension and swivel where necessary. Insert two bolts a few turns into opposite corners of the oil pan.

Separate the oil pan from the block with a pry bar. Remove the remaining two bolts and then separate the oil pan completely with the pry bar. Scrape off the old gasket and seals with a razor blade.

At this point, the oil pan is removed. You can now clean the oil pan mounting area and prepare the new oil pan for installation.

Prepare the new oil pan

To prepare the new oil pan for your 2004 VW Jetta, you will need to apply an adhesive to ensure it seals properly.

First, clean the oil pan mounting area, removing any remnants of the old sealant, and inspect the oil pump pickup for any debris. Clean as needed.

Next, apply a heat-resistant RTV silicone adhesive to the top of the new oil pan. Circle each bolt hole and check for any gaps in the bead of adhesive.

Once the RTV is applied, you can push the oil pan into place and start threading the bolts.

Install the new oil pan

To install the new oil pan on your 2004 Jetta, first, apply RTV to the top of the oil pan, circling each bolt hole and checking for gaps. Next, clean the oil pan mounting area, ensuring it is free of oil. Push the new oil pan into place, and start threading the bolts in an opposing or crossing pattern. Insert the three 16mm bolts into the side of the oil pan and tighten them to 45Nm (33 ft./lbs.) or 50 foot-pounds of torque. Tighten the 10mm bolts to 20 foot-pounds or 15 NM (11 ft lb).

Apply RTV to the pipe mounting area, push the pipe into place, and insert the two bolts, tightening them with a 5mm Allen bit. Refit the splash shield by clipping it into place and inserting the T25 bolts.

Lower the vehicle to the ground, refill the oil using a funnel, and run the engine briefly. Check the oil level and add more oil if necessary.
