You can go to your local automotive store and ask which kind of refridgerant you need (Example. R-134a). Once you know this they should give you a can and the instructions will be on it to tell you how to do it! Please be careful and wear rubber nitrile gloves, eye protection and ear protection (compressed air gets noisy if it slips).

Have a good day!

How do i replace the air conditioner coolant?

Buy R134a refill kit from parts store or WalMart. Pressure connection is on passenger side near the A/C drier which looks like an aluminum cylinder about 6or 7 inches high. The kit comes with a gauge and refill instructions, you will hook the gauge up to the port there in the coolant tube (remove the black cap to expose port) and the coolant canister screws into the gauge. Follw refill instructions for reading the gauge, etc. The motor must be running with A/C turned on Max cool with temp setting all the way to cold.

My 1998 jimmy has always leaked antifreeze but the last month it has got bad to were i have to fill it up everyday

You need to get or rent a coolant system tester and identify where it is leaking from. They are very simple to use. You just remove your radiator cap and install the tester and pump up the cooling system and then you watch for where the coolant is coming from. Look closely at your water pump, intake manifold gasket, radiator, heater hose coupler on the intake manifold, and coolant hoses. Those are all the common leak areas.

My 1995 gmc jimmy over heats when i run the ac good on coolant and fliuds is it a thermostat? and where is it in my coolant system?

CHeck the drive belt perhaps it is loose and when you put the extra load on the coolant system the fan is not moving enough air to cool the engine. There could also be a blockage in the radiator core. THe water pump may also be faulty

1999 GMC Jimmy Running Hot w/ Engine coolant reservoir empty

I guess the burning question is , where is the coolant going.
Is this a 4.3 engine? How many miles does the vehicle have?
Has the intake gasket been changed?
I'm guessing a can of "Bars Leak" may cure your problem.
Let me know.
