Mercedes Sprinter SR103 Passenger Side Rear Quarter Cutout Overview

The illustrated red line identifies the approximate inner stamped sheet-metal area that must be removed from the Sprinter passenger side rear-quarter panel.

Use the factory body stamping, illustrated guide, and actual SR103 window together when identifying the cut area.

After cutting, the exposed opening should be:

1. Filed smooth
2. Deburred
3. Protected against corrosion
4. Finished with Trim-Lok edge molding
5. Vacuumed and cleaned thoroughly
6. Dry-fit with the actual SR103 window before automotive urethane is applied

Step-by-Step Mercedes Sprinter SR103 Window Installation

Step 1 — Verify the Passenger Side Rear Quarter Position

Confirm that you are working on the passenger side rear quarter of the correct Sprinter body configuration.

Before cutting, inspect the interior of the panel for:

• Electrical wiring
• Factory brackets
• Insulation
• Interior wall systems
• Rear HVAC components
• Aftermarket accessories

Step 2 — Identify the Inner Sheet Metal to Remove

Use the Sprinter factory stamping and illustrated red line to identify the approximate inner sheet-metal area that must be removed.

Verify the intended opening with the actual SR103 window before making the first cut.

Step 3 — Cut From Inside the Van When Possible

Whenever practical, perform the cutting operation from inside the Sprinter.

Working from inside provides a direct view of the factory stamping and helps reduce the chance of damaging the exterior body surface.

Suitable cutting tools include:

• One-handed reciprocating saw
• Pneumatic air saw
• Compact automotive body saw

Use a blade designed for thin automotive sheet metal and make controlled cuts.

Step 4 — Remove the Cut Sheet-Metal Section

Once the perimeter is fully cut, carefully remove the unwanted inner sheet-metal section.

Inspect the opening for:

• Remaining metal tabs
• Sharp corners
• Saw burrs
• Raised metal
• Irregular cutting areas

Step 5 — File and Deburr the Opening

Use a metal file or deburring tool around the entire cut perimeter.

Remove all sharp points, raised edges, burrs, and high spots.

The finished edge should be smooth enough to accept the Trim-Lok molding without interference or distortion.

Step 6 — Prime and Protect the Raw Steel

Freshly cut automotive steel should not remain exposed.

Apply suitable corrosion protection to all freshly exposed steel.

Suitable options may include:

• Automotive rattle-can primer
• Automotive touch-up primer
• Urethane-compatible primer where appropriate

Follow the primer manufacturer's recommended drying or flash time.

Install Trim-Lok Edge Molding

Once the cut edge has been filed, deburred, and protected, install Trim-Lok edge molding around the finished sheet-metal opening.

Trim-Lok helps:

• Cover the cut metal edge
• Protect against sharp exposed steel
• Improve the finished interior appearance
• Conceal minor cutting irregularities
• Create a cleaner professional finish

Step 7 — Clean the Rear Quarter Body Cavity

Vacuum the opening and surrounding rear-quarter body cavity thoroughly.

Remove all steel fragments and cutting debris before final installation.

Step 8 — Dry-Fit the Actual SR103 Window

Before opening the urethane, place the actual SR103-AW, SR103-CA, SR103-F, or SR103-DS into the prepared opening.

Inspect the entire perimeter for proper clearance.

The window should sit naturally against the intended bonding area without being forced against remaining inner sheet metal.

If interference is found:

1. Remove the window
2. Identify the contact point
3. Carefully adjust the opening
4. File and deburr the adjusted area
5. Re-prime any freshly exposed steel
6. Reinstall Trim-Lok where needed
7. Dry-fit the window again

Urethane-Bonded SR103 Installation

Current SR103-AW, SR103-CA, SR103-F, and SR103-DS windows use urethane-bonded installation.

Prepare the vehicle and glass bonding surfaces according to the requirements of the automotive urethane system being used.

Surface preparation commonly includes:

• Cleaning the body bonding surface
• Cleaning the glass bonding surface
• Applying required body primer
• Applying glass primer where specified
• Allowing proper primer flash time

Apply a continuous automotive glass urethane bead around the required bonding perimeter.

Avoid gaps, thin areas, or inconsistent bead height.

Step 9 — Install the SR103 Window

Carefully position the SR103 window into the prepared rear-quarter opening.

Apply even pressure around the perimeter so the urethane bead makes consistent contact.

Tape or support the window during curing according to the urethane manufacturer's instructions.

Do not drive the Sprinter until the urethane has reached the manufacturer's specified safe-drive-away time.

Common Mercedes Sprinter SR103 Installation Mistakes

Assuming Every SR103 Model Has the Same Wheelbase Fitment

Verify the exact model before ordering. Current SR103-AW, SR103-F, and SR103-DS listings specify 170" wheelbase, while SR103-CA additionally lists 170EXT compatibility.

Cutting Before Having the Actual Window

Always verify the real window against the body opening before making permanent cuts.

Cutting Too Much Sheet Metal

Remove only the amount of material needed for proper window clearance.

Skipping the Dry Fit

Always test-fit the actual SR103 window before applying automotive urethane.

Leaving Burrs Around the Opening

File and deburr the complete perimeter before installing Trim-Lok.

Leaving Fresh Steel Unprotected

Prime or otherwise protect all freshly exposed automotive steel.

Leaving Metal Shavings in the Rear Quarter Cavity

Vacuum the body cavity thoroughly after cutting.

Using Household Adhesive

SR103 windows are designed for installation using suitable automotive glass urethane.
