How to Choose the Oil and Fluids for a Mercury Cougar

The Mercury Cougar has been presented in a variety of categories over the years, finishing its run as a sport compact from 1999 to 2002. While maintenance recommendations for previous model years are similar, these steps apply specifically to the 1999 to 2002 sport compact model years.

Instructions

1

Top off your Mercury Cougar's brake fluid with high performance DOT 3 brake fluid in North America, or DOT 4 brake fluid in Europe. The fluid you choose must meet Ford specification ESA-M6C25-A in North America or ESD-M6C57-A in Europe.

2

Mix Ford Extended Life Engine Coolant or a DEX-COOL equivalent with an equal part distilled or clean, drinkable water.

3

Change your engine oil regularly, using Super Premium SAE 5W20 GF3 motor oil. Look for the API certification mark and a label that states the oil meets Ford specification WSS-M2C153-H.

4

Use Motorcraft MERCON automatic transmission fluid in your power steering reservoir, automatic transmission, and manual transmission.
