This isn't specific to any vehicle, it's generic to all A/C systems. You always add refrigerant to the "low" or "suction" side. There are two tubes connected to the A/C compressor, one will always be larger in diameter than the other. The larger of the two is the suction side, so locate the compressor, then follow the suction line until you find a charging port -- it's often near and sometimes actually on the compressor.

If you had to disconnect an A/C line to replace the heater core you may need to evacuate the system before charging with refrigerant. Sometimes you can get away with just purging the system, but the price of refrigerant raises the stakes of that gamble (plus it's not a very eco-friendly thing to do.)

Always connect fill/gauge hoses to ports while the system is OFF, but NEVER add Freon unless the system is running (unless you know EXACTLY what you're doing.) Don't over-fill. Keep the refrigerant can upright while adding to avoid introducing liquid refrigerant into the suction side.

It's quite possible, not even especially difficult, to destroy a compressor by improperly charging, so a bit of extra care is due.

SOURCE: where and how to change cabin filter chevy equinox

Hiya...the cabin air filter is located below the front passenger/windshield area.
It's only accessible by standing outside the Equinox with the hood open.
Here's how to do it...(before you pop open the hood)

1) Stand outside at the front-right door area.
2) Just below the front windshield area, pull up a few small black plastic clips that's on the black windshield wiper cowl area- a small flat screwdriver or a special clip-remover tool is handy.
3) Raise the hood up.
4) There may be a triangular-shaped hard foam sound damper at the left side nearby the hood hinge...pull it off if it allow you to work around it with ease.
5) Continue to find a few black plastic clips around the black windshield wiper cowl area.
6) Gently pull up the black windshield wiper cowl cover with care not to bend it too hard during removal.
7) You should see the cabin air filter inside that's held in place by a black rectangular box inside.
8) There's 2 black tabs that holds the cabin air filter in place.
9) Insert your finger or tool to pry the cabin air filter away from the tabs.
10) Remove old cabin air filter.

Remember to reinstall the clip parts back into place when you're finished.

Not a whole lot different. Just need to keep removing plastic down at the heater until you get to the heater core. Then disconnect it on the firewall side.

I have 2006 chevy equinox code po455 I change the fuel cap and the purge evap valve but my code comes back what else could it be?


As you know one of the problems can be the Fuel Cap. I make this suggestion. If you changed your Fuel Cap before the Purge Valve double check that the cap used was an OEM (Original) Chevy Part for that specific vehicle, not just any cap from another Chevy.

Where do i ad freon to my chevy equinox


You shouldn't ever have to add freon to an a/c system. It is a closed system - like your refrigerator. When was the last time you added freon to your refrigerator or home a/c when there wasn't a problem?

If you are needing to add freon, then you have a leak somewhere that needs to be repaired. Your local automotive technician can diagnose the problem for you. Freon should only be added by trained professionals. If you don't know what you are doing, you can charge the system incorrectly causing significant damage to the system.

If you still want to do it yourself, reference this article.
You will need a set of A/C Gauges, and freon.
Do NOT put any type of stop leak into the system - this can cause irreversible damage to the compressor.

I just changed the water pump, thermostat, and flushed the heater core. I ran the car for a while with the surge tank cover off and kept filling it. As soon as I got on th e-way it overheated.


The surge tank should only have a little water in it, not full. I hope you didn't overfill it, this can cause your problem, but I would look at the radiator and make sure it is not plugged and your cooling fans, make sure they are running as well. Then last but not least your water pump may be bad even though you changed it, check for good flow through the radiator, if flow is good and strong then check the fans. You have already done most of what can be done, make sure the thermostat is not in backwards, in fact take it out and see if the car runs cooler, this will help pinpoint the issue also.

Fog in vents


You have a leak in the heater core or water build up as the dealer described to you. If it smells like anti freeze it is the heater core. If not pour a bottle of peroxide through the evaporator box which is the fiberglass housing mounted on the right side of the firewall. That has the blower motor attached to it as well. You will need to drill a small opening at one corner which will be safe to do and place a funnel in the hole drilled to add the peroxide into this housing. It will clear out all foriegn matter in the drain tube to eliminate this problem. After the peroxide sits inside this housing for 5 minutes pour one gallon of water to flushout the remaining peroxide and check if it drained thoroughly. If not repeat this process again

My heater stoped blowing hot air.antifreeze level


If the blower is blowing air just fine, but you cannot control the temperature, you need to listen to air coming from the vents while turning the temperature from hot to cold. If you do n ot hear any change in airflow, then you may a temperature door in the dash broken. this is becoming a common problem on the Equinox and Pontiac Torrent,
