Need to Add air conditionaer coolant

You should have a vacuum puller, but alternatively, you can purge it by letting in freon on the low side and opening the high side for about 4 seconds, that should purge all the air in the system.

You wouldn't add new coolant, then ruin it with some type of
flush product

Install the new radiator after you flush the system with clear water
& add new coolant 50/50 or 60/40

Do you have some type of problem that brings this question
about?

check and make sure you do not have leak and that your not loosing coolant it takes a few minutes for the new one to open just long enough for it warm up but you may just have air in your system common problem shut if off let it cool a bit take the radiator cap off if you hear air then you know got air in their and add coolant as you need envoys have a large cooling system so it takes more coolant than one would think.if i remember right they use the orange dex-cool type good luck to you

Lack of Coolant wouldn't cause your AC to blow hot air.

You may have a vaccum leak in your dash board that is causing your heater to remain stuck.

If not this, then you will have to have your AC recharged. You can purchase a recharging kit from your local auto parts store! Fortunately, your vehicle can use the newer type of AC Recharging kits so you have many options!

Good luck and I hope this helped!

Glycol based (green color) 50/50 with water is fine. Just make sure you bleed the system if you need to add alot. Trapped air in the coolant system can cause overheating. Also, change your thermostat every 30k miles.

There is a coolant reservoir on the driver side of the engine compartment. You just need to take the cap off and add coolant to the max lever when the car is cold. Never open it with the engine hot. Then you need to use the coolant type G12. You won't find it anywhere else but directly from the dealer. Its very important to use the this type of coolant so you dont damage any component of your cooling system. You're be paying about $17.50 per galon of G12 or price may be different depending of which state you're at.

What I do is park the car uphill. Let it cool, open the cap, start it, and let it warm up until coolant flows in the radiator. Add coolant and let the air burp out until there is good flow with no bubbles coming up.

Just make sure that the coolant is mixed 50/50. Don't worry about the color. You can buy coolant pre-mixed, which says you the trouble of mixing it yourself. Hope this helped.

flick the clips pull the lever and then take the filter out

Hi,is never a bad thing to add a good fuel injector cleaner to your gas tank to prevent injectors from getting cloged ,you can try this for two days ,if no diference , check your air conditioner idle compensator,this regulates the idle when you turn the air on and off. good luck
