< Go Back How to fit a Mercedes Sprinter Windscreen the easy way Posted: Jan 17, 2017 These fitting instructions refer to the Mercedes Sprinter part number 5439 and the VW Crafter part number 8590. Any windscreen fitter should be able to undertake the entire process on their own.
Masking tape the top of both wings prior to removing the bonnet, this prevents the wings from being damaged during the removal of the bonnet. 4 in number 13 mm nuts are removed from the two hinges along with one 13 mm bolt on the bonnet stay.
Lay the bonnet in a safe place either on the ground or in the back of the van.
Remove the wipers, I normally leave the washer tubes connected. Remove the windscreen moulding and the old windscreen. My personal preference for removing the old windscreen is a Kent knife. Go round all four sides with a 0.75 inch blade followed by a one inch blade, on most occasions the windscreen will lift out without the need from getting in the vehicle.
Prepare the glass and bodywork in your normal way. The centre mark of the vehicle is a small line on the dashboard the passenger washer jet also denotes the centre mark.
The new windscreen should have a small "V" in the ceramic band at the bottom of the glass to denote the centre of the windscreen. Place a mark on the outside of the windscreen so this is visible once the trim is placed round the windscreen. Tape the trim to the glass on the bottom of the windscreen, this will ensure the trim stays in place during the lifting process.
Place the adhesive on the glass, the normal quantity required is 500 ml, I normally try to place any joints on the bottom of the windscreen. Turn the windscreen over and place two glass lifters on the windscreen in a comfortable position to enable lifting. Lift the windscreen into position from the front of the vehicle, line up the centre marks on the windscreen and body and lift the windscreen forward.
Refit the wipers and bonnet. This fitting method produces 100% accuracy with no chance of water ingress or loose trims and avoids damage to the pinch weld with any type of slashing knife. No black primer required to cover up scratched pinch welds.
Fitting time is 45 minutes to an hour
