How manu cans of freon do i need - 1999 Oldsmobile Silhouette

Hello
u'd need a proper manu al for this in my opinion
like there are plenty of dealers and online shops that deal in those..
you can get some free at reliable-store and it;s actually really illustrative

Go to a ac shop this is dangerous and in some cases ******* depending on year of vehicle. If you are talking about remove old freon and replace with new freon need special equipment.

If I understand your question, the manu allows you to shift like a regular stick shift. The power will allow the revs to go higher than in normal for extra power/acceleration.

these are to raise or lower the transmission shift arm to either get more Power from your engine or use the Manu to lower in order to get more economy from your engine.

What ????? i try to sterted manuely and it start but turn off the light stays on with the ignition. What light stays on ????

i try to sterted manuely ???? I try to start it manually !!!!!!! You need to take your vehicle to a qualified professional technicia .

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.

mcdevito75 here, Yes you can tow a trailer, your local parts store can provide you with the info, or better yet any Dodge dealership.

2 lbs of freon is all you need if empty, replace your low pressure switches, sit on a thin a/c line running on top of your fire wall from one end to the other, you will need to recover the freon before you can replace these two sensor's. These sensor's are bad that's why it reads on your dash low freon.

The PWR button (power) is like a sports mode. It keeps in lower gears for longer so you can gain more speed. Handy for overtaking or fast lane changing. Not wise to use this all the time due to poor fuel economy.

The MANU button (manual) allows you to operate the gears manually. With MANU on and gear lever in L, it will drive in 1st. Gear lever in 2, it will drive in 2nd. Gear lever in D, it will drive in 3rd. If Overdrive is enabled then D will give you 4th gear instead.

your system needs to be cleaned out and converted to r134 or you can try a r12 substitute
