Parts for your 1999 Ford Mondeo-Oil cap

1999 Ford Mondeo oil cap — purpose, care, and replacement

An oil filler cap is definitely used on the 1999 Ford Mondeo. Factory documentation shows it across the petrol Zetec‑E (1.6/1.8/2.0), Duratec V6 (2.5), and 1.8 turbo‑diesel engines. The owner’s guide for the 1999 Mondeo identifies the oil filler cap on the cam cover under the bonnet, and the Haynes Ford Mondeo 1993–2000 manual lists inspection of the cap and seal in its weekly checks. Ford’s ETIS/TIS parts catalogue also specifies a dedicated filler cap and seal for these engines. So it’s a required, serviceable part on every 1999 Mondeo. (Sources: 1999 Ford Mondeo Owner’s Guide
