Need to add 13-4a freon to my 2000 venture chevy van. Where is the pressure hose located?

best advice is the method i would use to located the orifice tube in the 2000 chevy venture. check the automotive repair book section in your local library. Most libraries have repair manuals on their automotive shelf section. find the a/c manual for your year and model car. make a copy of the page that has the information you need. you will need to make a copy because the library will not let those manuals be checked out. you might want to google for the location of the orifice tube location. I hope this helps.

Why would you change a crank sensor

It failed a test?

How was it tested?

No parts get changed just for something to do

My 2000 chevy venture just started this and I took it in to get looked at...it is the Pressure silnoid. And it happens when the van gets warm. The cost is up to $1200

take the bottom hose off ,

Get an r134a refrigerant add kit from Walmart or your local auto parts store.

You can even get a can of Arctic Freeze by Intermatics that has a hose and a gauge on it.

Connect the hose to the low side port. You can find this port on the 'thicker' piping that comes off of the compressor (versus the thinner piping that comes off the compressor which is the high pressure side).

Pressure should read 25 psi to 45 psi on the low pressure side when the compressor is running and the a/c is on.

Pressure should read 75 psi to 100 psi on a hot day when the car is off.

However, you'll want the a/c to be running when you add freon.

Press the button on the can to install more freon, if needed.

The drain is just a small hose coming out of the firewall, right hand side, about 2 -3 inches long, they get clogged up with mud, bugs, you name it, and when the clog up, it's like Niagra falls in there. Check it out.

all you gotta do is follow the top radiator hose to motor,it;s where the hose meets the motor.

distributor is advanced

if you can locate where your a/c compressor is under the hood there will be two hoses coing from it your high and low you need the low one it will be smaller than the high Good Luck

use the pressure test port on the top of the engine, it is on the fuel rail that supplies fuel to the injectors, looks like a tire valve, will have a plastic cap on it.
