A4/NB TDI Engine Tools for 1999.5 Golf/Jetta and all New Beetle TDI timing belt replacement: 1. Injector pump alignment pin (3359) 2. Cam gear puller (4001) 3. Alignment guide plate (3418) 4. Cam gear holding bar (3036) 5. Toothed belt tensioning tool (T1020) 6. Stubby 5mm Driver (1/4” drive) Note paper towels stuffed into the intake to prevent “Murphy’s Law” from kicking in.This keeps you from dropping that flying spring clamp into an intake duct!! Raise up the power steering reservoir and pull the coolant reservoir hose under and to the front of the car. Cover the fender and let the coolant reservoir hang on the front of the car.upper timing belt cover and the flex line coming from the air filter going to the engine. I strongly suggest stuffing some paper towel in both holes to prevent you from dropping something into the turbo inlet. Using a 5mm 3/8” drive allen socket, remove all the front and driver side rear allen bolts except for the two by the oil filler cap. For those use the special cut-off 1/4″ drive socket that you made to remove them. Believe me when I say this, I have tried EVERY possible way to do this and I have stripped out a few heads in the process and this by far is the only true easy way to do it. Also disconnect hose to the valve cover, plug and and secure it.
