It should be under the intake manifold/under the large wiring loom and then under that is a large water hose. It's under there. Takes around 3-4 hours to replace. Nice design on those tune up parts Ford... BTW, while you're under there you might as well also replace the back 3 sparkplugs. On my 2001 Ford Taurus SEL, 24 valve, DOHC engine, the pcv valve is located not where you think it would be. The best way to tell you how to locate it is to follow one of the largest hoses (it's not big...probably 3/4 i.d.) coming out of the throttle body and follow that down to where it mates up to the pcv valve. To help locate the hose, it will be underneath the throttle body and will have a grey hose clamp. The hose will also form an "L". It also turns to a plastic hose too, if that helps. So... rubber "L" hose to plastic hose back to rubber fitting, then the pcv valve. Another description...The pcv valve is on the driver's side of the car, in the top-middle of the engine under a wiring harness and close to the fuel rail. Naturally, Ford put this next to a lower radiator hose entering the engine block too. In all, it's in the worst spot ever for a pcv valve, if you ask me. I hope the engineers saw a good reason for this, because this is definitely not an easy one to access like 95% of all vehicles (usually on top of the valve covers of most cars and you can change in like, 2 minutes at most). To access this, you really need to remove the whole plastic intake and throttle body. Maybe a professional mechanic could do it without doing this, but I'd have to see it to believe it. One more thing I forgot to add. The pcv valve for this is made by Motorcraft (part number EV-243 or part number EV-268) EV-268 has a metal hose wrapped around the part. I was told that on some Ford minivans, the metal tube is for coolant to run through.... I guess to keep the valve cool. Anyway, you won't need this for your Taurus. Simply bend it slightly and pull it off. The valve, you'll notice, has square-like sides. This is to allow you to put a pair of pliers on it to remove the old and insert the new. The part has to be turned about a quarter turn counter-clockwise to remove and the opposite to install. You'll also see that it has a rubber o-ring on it to seal it in the block. You won't be able to reach it well with just your fingers, unless you were to remove the wiring harness and fuel rail. So... simply use a pair of pliers to reach under the wiring harness and grasp the square-sides of the valve and twist it counter-clockwise to remove. I didn't need much pressure at all to remove it, although I read online where one guy's cracked when he did it. He claimed it was in there so long that the piece was seized in the opening. Mine simply twisted out and I twisted the new back in. It is below the egr valve close to the intake manifold below the intake air sensor, there is a tube running to it from the engine to recirculate exhaust air with fresh air, there is a clamp holding it to the air intake that you need pliers to remove, then you need to turn counter-clockwise 90 degrees to remove, do the reverse to install. to make it easier to access remove the upper intake. The pcv valve is not visible, however, you can identify it by the 3" inch rubber hose that connects to the steel line running into the bottom of the intake. I have the part and am going to replace it soon, although Ford really makes it difficult to remove it - I have a Ford Taurus 2000 with DOHC engine
It is located on the drivers side crankcase, just below the upper intake manifold. You will need to remove the air filter assembly, the throttle cables, and you might need to move the other bar that is connected with maybe 5 sensors, to be able to get to it.
The 2001 Mercury Sable PCV valve can be found on top of the engine. The PCV valve will be on the back side of the air cleaner housing.
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 , in a 2003 Mercury Sable : The 3.0 liter " Vulcan " V6 engine is an overhead valve / pushrod design engine that uses ( 1 timing chain ) The 3.0 liter DOHC " Duratec " engine has ( 2 timing chains , 1 chain to each cylinder head )
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 )
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 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
The 1989 Mercury Sable 3.0 liter engine EGR valve is located on the firewall. The valve will be on the passenger side of the firewall.
The only way to change the plugs is to remove the top cover first. Then remove the cover for each plug.
Autozone as of late 2009:12 valve Vulcan engine: $30-4524 valve Duratec/DOHC: $65See "Related Questions" below for more
On a 1998 Mercury Sable : No , there were ( 2 ) engines offered from the factory The 3.0 litre " Vulcan " V6 ( which is an Over Head Valve / pushrod design engine and the 3.0 litre " Duratec " V6 engine ( which is a Dual Over Head Cam design engine )
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
It will say it right on the top of the engine. Anything that is DOHC will have it on there. =========================================================== The 1996 Mercury Sable had 2 different engines from the factory : They were both 3.0 liter V6 engines The " VULCAN " which is an Over Head Valve / pushrod design engine and the " DURATEC " which is a Dual Over Head Cam design
