Replacing pcv valve on 06 gran prix cannot where it is located

Go on U-tube and you can find several individuals that have videos that show step by step on how to change the heater core on your or any vehicle.

there is no PCV valve. Its replaced by some sort of metering tubes.

PCV valve is usually in the valve cover with a plastic or rubber hose attached to it. You may have to remove the plenum cover on the top of the motor to get to it.

PCV Basics
PCV stands for Positive Crankcase Ventilation.
All car engines have a PCV valve and it is located on top of the motor's valve cover. There is a vacuum line attached to it. It pulls out of the valve cover and if you shake it, you should hear a marble knocking inside it. If you shake it and don't hear anything, it's bad. It costs less than 5 bucks to replace.


Location
* 4.0L is located in the valve cover near the brake booster
* 5.0L is located behind the intake manifold (engine rear)

NOTE-Most people that are asking actually want to know not only where is it but also how do you get at it to replace it.

Often answers say that you need to dismantle the intake manifold to get to it.
This is a major and unnecessary approach, for example, on the 2000 Explorer with a 5.0 V8

Below is an additional suggestion on how to access a PCV valve on an 2000 5.0 V8 Explorer

The PCV valve is on the rear of the intake manifold (the intake manifold is also on top of the crankcase so PCV valve has direct access to crankcase)

To replace valve and/or its bushing:

• Disconnect one battery terminal, unbolt/unplug the PCM cable (Powertrain Control Module connector located on the firewall) and firewall ground connection, depress underneath tab and slide the main cable connector (located to the right of PCM connector) off its mount.

• Move the cables to the right and now you can easily reach down behind the intake manifold to the PCV valve

• Service valve and its bushing if needed, reverse actions to reassemble

Hope this helped (remember comment and rated this). Good luck.

If leaking coolant under dash on passenger side floor broad it's your heater core. Call's for 2.8 labor flat time to remove heater core, in some case's you'll have to recover, evacuate and recharge your A/C system to remove your heater core.Sit under dash on passenger side.

If I remember correctly this vehicle has a plastic plenum and the pcv valve is inside the plenum. Only time it is usually replaced is when the intake gasket needs replaced (and it will).

The upscale model is the only that i know of that has one. What model do you have?

What throws everybody is that the pcv valve does not insert into the valve cover as it does most cars. This one on the 1999 explorer is located directly behind or in back of the engine on the top of the manifold. You can spot this easier if you take off the covering(four screws) on manifold then you will see two hoses that connect to a plastic pcv valve (that's what threw me). this should help.

pcv valve on a 3.1 L is located in the front valve cover on top of engine. Hope this helps

the pcv valve will be sticking out of the valve cover in either the front or back. and as for the dexcol, i would have it flushed really well and replaced with the reg green coolant. ive seen that stuff get bad quick.
