There isn't one. Only on a 2004.
On the throttle body
The EGR valve on a 1979 F150 with a 302 is located in the center of the engine. It is close to the firewall.
PCV Valve is located on the Right Valve Cover.
PCV valve located on a 2003 ford f150 4.2?
Doesn't have a cooling system bleeder valve.
I have a 5.8L in my 1990 and it is located behind the intake on the passenger side. Right by the valve cover.
Need more info. Which valve are you referring too?
On top of the valve cover , near the rear of the cover
Inline in one heater hose underhood near the HVAC box (right hand side underhood.)
It's located on one of the valve covers. The breather is on one and the PCV valve is located on the other one. and it will have a hose coming off it. Hope that helps.
