I was just looking at the 2002 Mercury Sable owners manual and the
drawings of the " Vulcan " engine and the DOHC " Duratec " V6 engine
When standing at the front of the vehicle , the dual over head cam engine has
the engine oil fill cap on the left side of the valve cover ( passenger side )
where the Over Head Valve " Vulcan " engine has the oil fill cap on the right
side of the valve cover ( drivers side ) and ( 1 ) coil pack with ( 6 ) towers
next to the engine oil fill
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 )
Where is the dual overhead cam located or the air temp charge sensor?
If you change the whole engine.
The answer is very dependent on which engine - Ford used at least 2 different engines that year, including the DUAL overhead CAM (DOHC).
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 )
For a ( 2002 ) Mercury Grand Marquis : 220 horsepower ( 235 horsepower with dual exhaust )
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.
The SL series came equiped with either a single overhead cam or a dual overhead cam engine. If yours has the single overhead cam, it's the SL1. If yours has the dual overhead cam, it's the SL2. Open the hood, look at the engine and see what's on the rocker cover; if it says DOHC or "Twin Cam", you are the proud owner of a SL2.
all the civcs have a single overhead cam motor(sohc) the civic si is the only one with a dual overhead cam motor
