My 1996 Acura 3.2TL prem. is overheating... yesterday, I filled up the radiator[in the morning while it was cool] went on a 200 mile trip and then the radiator was EMPTY 4 hours into the drive[the temp was high and the car was overheating]... I had to stop and refill the radiator as if there were no fluid in it at all! Before adding the fluid I checked the ''radiator fluid nut''[towards the engine], to release the bubbles, but no fluid was coming out, so that is when I filled the radiator... After I filled it up with fluid, it began to ''bleed'' from the ''nut,'' I waited until the bubbles were gone and then I tightened the ''nut.''
My thermostat was changed and my radiator was newly changed 2 months ago... My car over heats with steam coming from the hood... A closer look shows the steam coming from the reservoir[RSVR] container which is connected to the radiator by a small diameter hose[hose goes through the RSVR container cap]... The fluid inside the reservoir appears to be rapidly boiling... steam/smoke comes out of the reservoir cap... upon removal of the RSVRcap[with hose], there is hot smoke/steam coming out from the RSVR cap hose...
no steam is visible from the radiator or the larger diameter radiator hoses... under the vehicle, there is no evidence of a leak, there appears to be no fluid on the ground[no puddles] or leaking... upon starting and reving the engine, there is NO blue or NO white smoke coming from the exaust... The radiator hoses appear to be fine [HOT to the touch when overheating]... the cooling fan DOES go on when temperature is high... Vehicle does not appear to loose power while driving...
From your description of symtoms it sounds like you have a bad water pump. If the coolant is not circulating properly you will have a heating problem. Sometimes even a new thermostat can stick and cause the engine to overheat. I have seen them fail in as little as a week after they were installed.

have a compression test done to check head gasket and for cracked heads . Have the radiator flow tested as the previous owner probably used a second hand unit to sell the car that was partially blocked any way.
if all hoses are ok and there are no leaks have a look at the thermostat most anti freeze is already mixed so you can just put it in any way and what was said above wouldent make it over heat has it just started doing this or is it an ongoing thing are you getting back presure when filling make sure engine is not hot pref first thing in the morning when the radiator is full squeeze the top rad pipes to get any are out of the system then start the car dont rev just let it tick over the water pump will move the water around the engine keep an eye on the level and top up again untill it stops needing any any exess fluid will come out of the over flow pipe or back into return bottle if it still over heats get the thermostat checked is the car running fine or is there any other problems apart from this as there are a few more things that can make it over heat timeing sticking valves etc hope this helps ivan
I do not understand what your problem is so i will try to see if i can tell you what i think you are saying, the car is leaking coolant from the radiator, if this is correct then replace radiator. or is the coolant spilling out because engine temp is overheating , if the engine is overheating this will cause the ac system not to cool down and make the cold air hot due to the condensor not cooling,
The first step is to repair any leaks and also make sure the radiator fan turns on to cool engine, when you turn on the a/c the fansss will run, if they do not then have the fans checked.
replace the cap , its allowing the system to over pressurize, also, you could have an air bubble thats moving around in the system, always make sure that you fill the radiator to just cover the radiator fins inside, this allows a place for expansion to happen. what you need to do is BURP your system, leave the cap off and start the vehicle, ( before doing this step,, make sure that you've replaced the thermostat, spring towards the motor , it only works one way!! ) once you see the fluid inside the radiator moving, it means the thermostat has opened, and your fluid level should drop down, slowly add more until the fins are just covered, and wait for it to close and recycle one more time, refill again, that should purge the system of unwanted air,, replace the cap, and fill the over flow tank to the lower level line,, and you should be set
Check if the Fan is working normal, also check if the water is at the normal level. Make sure the water is not filled up because it has it normal water level.
I had the same problem, whole new radiator, new hoses, new thermostat, and still overheating. What the problem was for me...bad radiator cap...all that money and a $20 fix...try it?
have you changed the thermostat? located at upper hose opposite radiator end in the gooseneck (usually 2 screws) make sure you buy a gasket or gasket making compound if changing. most overheats occur due to stuck thermostat (doesn't open to cool) you could pull tstat out for temp fix but it wouldn't heat well in colder weather
