On a 1996 Mercury Cougar : The 3.8 liter V6 engine has ( 1 timing CHAIN ) The 4.6 liter V8 engine has ( 1 timing CHAIN to each cylinder head , so there are 2 timing CHAINS )
The firing order for a 1990 Cougar 3.8 is 1-4-2-5-3-6. The number one cylinder is the front one on the passenger side.

Passenger side second cylinder from the front.
