Compatibility Chart
| Engine / Model | Recommended Socket Size | Drive Type & Profile | Depth / Fit Notes |
|---|---|---|---|
| GM Detroit 6.2 L & 6.5 L Diesels | 30 mm | 12-point socket, 3/8″ square drive with option for 7/8″ hex adapter | Deep enough to clear protruding nozzle components; avoid damage to nozzle body |
| Mercedes-Benz 606.910 / E300D (≈1995) | 22 mm (or 27 mm in some variations) | Deep socket; requires side cut-out or clearance for return line | Check hex size vs holder; ensure socket avoids interfering with return hose barbs |
| VW 1.6 / 1.9 TDI Engines | 27 mm deep | 12-point; 1/2″ drive | Long injectors or protrusions may need deeper socket or special clearance |
How to Determine Compatibility for Other Engines
1. Measure nozzle nut or nozzle body maximum external diameter using caliper.
2. Identify protruding parts (return lines, nipples) that may interfere and account for clearance or side cut-outs.
3. Measure depth from nozzle tip to mounting surface to ensure socket is deep enough.
4. Note drive type (6-point vs 12-point, square drive vs hex) that best fits your socket tool and engine design.
