The Fiat Ducato has a well known weakness in design - a poor seal at the base of the windscreen allows water, even in new models, to seep into the engine bay if not installed properly. Check yours today!

This eventually leads to a rusted engine block. This may cause issues ranging from piston function failure to total loss of engine!

See comment thread below:
"Be aware that any silicone products used on or near to the windscreen to seal will give you problems if you need a replacement screen. Windscreen repair/replacement companies will not fit a replacement screen if they suspect silicone around the seal or body of the vehicle. They will insist that you have the body resprayed to remove all traces of silicone before they fit a replacement. They do this to guarantee that their bonding products will not be compromised by silicone and in the event of an impact that the screen doesn't fall out."
