Under hood, passenger side, beside/next to radiator in the silver metal line that is going up and down. Remove that one nut on that fat looking strange looking fitting. There will be two of them but undo the one that is going up and down. Pull it apart, it will be down INSIDE the pipe. Reach it with needle nose pliers Pull it strait up & out. That plug and wire that will want to get in your way is the pressure sensor, try not to accidentally break it. It can be removed by unscrewing it.
What orifice tube? An orifice tube is part of the AC system pull off the lines going into the accumulator. You'll see it. DoratheExplorer
There is no expansion valve. There is an orifice tue. It is located in the inlet tube of the evaporator core.
It does not have a pcv valve. The system uses a fixed orifice in the rear elbow on the valve cover.It does not have a pcv valve. The system uses a fixed orifice in the rear elbow on the valve cover.
The O2 sensor is located on the exhaust system there might be more then one
Its hard to tell exactly, but if you look at the hoses and metal tubes of the a/c system you can tell. Find the small hard line running from the condenser (radiator looking thing in the front) follow it until you find a connector where it goes from that small line to a larger line and your orifice tube will be located there. Hope this helps.
It is on the accumulator.
The ac system on a Ram doesn't use an expansion valve. It uses a fixed orifice system.
Are you sure it has a fixed orifice tube system? Most heavy duty trucks use a Thermal Expansion Valve (TXV) system. In both systems, the metering device (orifice tube or TXV) is located between the condenser outlet and the evaporator inlet.
Orifice Tube
That would be the O2 sensor located in the exhaust system after the catalytic converter.
It's located on the left side fender well right before you get to the battery, look down and you will see a a/c line disconnect that line and it will be inside, you will needle nose pliers to pull the orifice tube out. >>> (your a/c system has to free of all pressure before you disconnect that line!!!!!)
The Wrangler uses a fixed orifice system. There isn't a pcv valve. The tube coming from the center rear of the valve cover is the orifice.The Wrangler uses a fixed orifice system. There isn't a pcv valve. The tube coming from the center rear of the valve cover is the orifice.
