In a 1999 Mercury Sable :
It depends on which engine you have
The 3.0 litre " Duratec " V6 engine is a Dual Over Head Cam design with ( 2 cams on the top of each cylinder head )
The 3.0 litre " Vulcan " V6 engine is an Over Head Valve / pushrod design engine
that has ( 1 camshaft )
The Mercury Sable and the Ford Taurus will have DOC in printed on the engine if they are dual overhead cam engines. The symbol should be on the top of the engine.
In a 1999 Mercury Sable : The 3.0 liter " Duratec " V6 engine is a Dual Over Head Cam design ( it has 2 camshafts on top of each cylinder head ) and The 3.0 liter " Vulcan " V6 engine is an Over Head Valve / pushrod design engine ( it has 1 camshaft )
The 1999 Mercury Sable came from the factory with one of two engines : The 3.0 liter " Vulcan " V6 engine , which is an Over Head Valve / pushrod design engine , or The 3.0 liter " Duratec " V6 engine , which is a Dual Over Head Cam design engine
Some do, most do not. Easy enough to look under the back end of the car and see if there is an exhaust on both sides.
On a 1996 Mercury Sable : There were two engines from the factory : The 3.0 litre " Vulcan " V6 engine , which is an Over Head Valve / pushrod design engine or the 3.0 litre " Duratec " V6 engine , which is a Dual Over Head Cam ( DOHC ) design
No Ford Crown Victoria or Police intercaptor has dual overhead cams. The dual overhead cam engines were only used in Mustangs and Lincoln MK8's.
Most cars today used dual cam or more for power efficiency and lower gas emission for longer mileage.
yes sir.
if the are both single over head cams or if they are both dual over head cams they will fit
The engines in a 2004 Mercury Sable do not have a timing belt The 3.0 liter " Vulcan " V6 engine has ( 1 timing CHAIN ) The 3.0 liter Dual Over Head Cam " Duratec " V6 engine has ( 1 timing CHAIN to each cylinder head , so there are 2 timing CHAINS
There is no timing belt on a 2003 Mercury Sable The 3.0 liter " Vulcan " V6 engine has ( 1 timing CHAIN ) The 3.0 liter " Duratec " Dual Over Head Cam , V6 engine has ( 1 timing CHAIN to each cylinder head , so there are 2 timing CHAINS )
Original dual overhead cams are at 198 degrees for my 1993 Probe Gt 2.5L New modified cams will be at 210 degrees intake and 200 degrees exhaust.
