Yep, that should work. The yellow hose is for adding the freon.

Yes, not that there is anything special about hose except it's color. More importantly the OP needs to know (if he doesn't already) that the center port on the manifold set is the service port. It is used for more than adding/charging the system. It also used to evacuate the system (of refrigerant) and when pulling a vacuum on the system prior charging. Some Manifolds have two service ports.

For some reason the hose sets don't usually come with a resealable can tap valve (don't see one in the pic either.

Pretty common. The manufacturers have no way of knowing what kind of can tap you need/prefer or if you are charging from a bulk tank, so they leave that up to you.

I'm very glad that you replied. Good points on the tap valve and gauges.

On a quest to find problems that aren't there..........


Question - is it normal for the AC line that runs on top of the radiator to be hot to the touch ?

My AC blows nice cold air but I was just exploring around under the hood and noticed that.

This all started because I'm wondering why my AC isn't producing a condensation drip under the vehicle on these hot days. My carpet is dry and I have that extension tube thing installed but no drops . Hmmmm

AC blows cold so I should prob not worry about this

Normal for the high side line (smaller line) to be hot.

No drip from the drain line (evaporator housing) depends on the humidity at the time.

I live in a humid climate so mine will pretty much drip anytime the A/C unit is running (summertime). BUT....it is possible for conditions to be such that a small amount of condensation simply evaporates before making a noticeable drip/pool beneath the vehicle.

Unless the line has been extended most drip somewhere on the firewall or vehicle frame/suspension before dropping to the ground.

It is also possible the line is obstructed. You could investigate that.

Good info, thanks. Sounds like the high side line being hot is normal. I'll have to research the drip a bit more, it is very dry in my area. The extension line is also close to the exhaust so it's so hot down there. I recently installed the cabin air filters and new door , I should go back in and pour some water in to check the drain.
