Changing my rad.I have new denso.

I started loosening this nit and heard hiss.

I tightened back up.Car is still warm so maybe thats why.

I have no idea what I am doing so not sure If I should proceed with looseming this nut?

Is it freeon leaking out?

This line runs to the ac pump??

Yes that is the AC system going to condenser. Tighten it back up and hope you didn't lose all your Freon. You may need a recharge.

I figured that out too late.

This car has 2 rads.

I never use the ac so I dont really care.

I realize I dont need to touch those fittings know.

Cant I just remove the ac rad to let the engine rad breathe better?

The ac rad is infront of the engine rad.

Another thing after pressure test.

He says waterpump is fine??

Yes, you can remove your A/C condensor. But doing so will open up the rest of your A/C system, compressor, tubing, orfice tube, accumulator etc to moisture and eventually ruin it all. If you ever plan to go back to having functional A/C, then button everything back up.

So removing these items totally,then storeing them would ruin them?

What if any advantages would removing be.

Basically I dont like how the condensor is basically ontop/infront of the engine radiator.

I would think nothing infront of the engine radiator would allow it to get much more air and cool off better.

P.S I forgot to put this back in.

I suppone it directs air onto rad,

It sits to the left of radiator..

No, if you remove the parts and store them, they would be fine. If left on the car, they would get mositure in them. I had an old Dodge van which were known for rear evaporator failure. A leak in it resulted in mositure making it's way all the way to my compressor, causing it to literally seize. I would minimally cover the compressor high side and low side ports with plugs if storing it. I agree that removing the condensor would allow more air through the rad.

Minimal advantages to removing the A/C components would be weight reduction, less parasitic draw on the engine from the compressor, even when freewheeling, a little more space in the engine bay for air flow. You would however have to find a shorter belt. It may not be worth the effort to remove the stuff.

I removed that plastic cover and used the space for a transmission cooler. I wouldn't sweat it, but it may keep your engine bay cleaner with it reinstalled. It is a bit tricky to reinstall without removing the bumper cover if I recall correctly. One of the plastic push pins is up under the crossmember, I think. It's been a while.

It'll take more than a few seconds to fully drain the AC system by just loosening one of the bolts, probably take a few minutes, it's also very frowned upon (and possibly illegal) to let the gas escape into the atmosphere. On another note, that gas sits at 40ish PSI and is cold enough to damage skin/tissue so IF you plan to open that system open it just barely enough to cause a leak and let it sit for a long while, don't risk opening it a lot. If you remove the condenser you can seal off the hoses that normally attached to it to keep the rest of the components from getting ruined. I learned that the hard way with another car, ended up hunting for weeks in junkyards to find parts once it came time to get the AC working again.

Seems to be cooling better with new rad so I should probaly leave on.

Is there any power loss with ac pump pully connected,but without ac actually on?

Good news. I think the load would be minimal with the compressor clutch disengaged.

You want your AC to work as it is also used to dehumidify when your windows fog up on the inside. Very important. OK
