Don't mess with this if the system is under pressure .
Take it to someone you can't fix the AC if you have opened the system moisture will get in and it won't work .
If this gas sprays into your eyes it will freeze them and you will never see again.

Not without spending alot more money than you want, because you have to have a shop release the ac pressure if there is any, see if you can find the complete hose, then get it re charged, unless you are certified it cost quite a bit

SOURCE: ac hose on my 1995 dakota keeps blowing on high pressure side

You have a blockage in the system, more than likely the expansion valve is stuck at the inlet to the AC evaporator core.

How do I change valve stem seals on a Skyteam ST50


This is not a "drive way" repair... you need to do one of two things.. sometimes you can get a connector that can replace the spark plug to keep air pressure in the cylinder (THAT CYLINDER MUST BE AT TOP DEAD CENTER ON THE COMPRESSION STROKE!!!!) that will keep the valves closed..( YOU MUST HAVE A LARGE HIGH PRESSURE-HIGH FLOW AIR COMPRESSOR!!!)..now you can remove the valve springs one at a time (have a way to compress the springs??) ..and replace the valve stem seals..one at a time.. IF you DO NOT have the tools to accomplish this, --- YOU CAN REMOVE THE HEADS.. hold the valves in place and remove the valve springs.. and then change the seals, you must have a valve spring compressor to accomplish this.
Does this seem like something you can do..?? If you have never done this??.. PLEASE just pay a qualified professional to change them!! You will need intake gaskets, head gaskets, valve cover gaskets, valve stem seals.. maybe the valves will need re-seating..
just to name a few things... get the idea...

How to get freon into my minivan with a good compressor and a clutch that works real quiet clutch that spins good


First you need to locate the low side of the charging system. This is usually determined by the connector you can get now days with the Freon. Not sure what year you are working with but the Schrader valve on the line will normally be two different sizes so you can not hook up to the high side. You can press down on the Schrader valve and if there is pressure in the system it will release a small amount of Freon, if you are trying to determine if it is allowing the Freon to enter the system. The Schrader valves screw in just like a bike stem valve does, if it needs to be changed. .

Ac drainline 2002 toyota camry


Hi Andreas, The valves for evacuation and refilling the ac are the same. To drain the system an evacuation pump should be connected to the low pressure and high pressure valves. The valves are situated in the engine compartment, the high pressure has a red valve cover and the low pressure black. You will easily find the valves by looking along the air conditioning plumbing.

I need a diagram of the A/C low pressure port on my 1996 chevy blazer. I know it is aways on the larger diameter tubing but it seems the port seems tube seems to be coming right off the side of large...


Find a shiny aluminum canister under the hood thats bigger than a soda can and follow the tubing that comes out of it back towards the front, you will come to a valve similiar to an air valve stem on a tire. The valve has a black plastic screw off cap. That is the low pressure port. The high pressure port is located behind or near the a/c compressor

Where do I recharge ac at


there are 2 ports one for low pressure and one for high pressure. the low pressure is bigger in diameter and is usually close to the dryer and or fender and firewall. the high pressure is near the condensor on the fron of the vehicle. if there are caps for the ports low will be blue and high will be red. low side pressure should be 35-50 psi and high pressure should be 135-150 psi
