There are two radiator like units in your system. First one is the condenser and is located at front of your car, just in front of the cooling radiator, and behind the grill. The other is locted inside a plastic case on the firewal behind the engine and under the windshield, and is called the evaporator. The job you are trying to do should be done by a technician with proper equpment. An electronic leak detecter, and a charging station w/vacuum pump are the basics. This can be an expensive repair no mater which one is the culprit.

    Okay, either one of these jobs are complicated and require the services of a trained technician, and special equipment. The two units you are talking about are quite concealed and difficult to see with some dismantling. Second, you probably wouldn't be able to see the leak, this is an invisible gas. An electronic leak detecter is required to locate your leak, and once you find the culprit, more than likely you will need to replace it, again this is complicated. Once repairs are made the system will require a vacuum pump and recharge, all of this requires special equipment. This is not a driveway repair job.

My 98 Buick century is over heating what is a possible cause


Wow. It could be a multitude of different problems. I will tell you a few things to look at first. Possible reasons of over heating include low water, thermostat stuck closed, no thermostat installed, radiator stopped up inside with gunk or outside with bugs, missing lower air dam, fan not running either because of a sensor or a bad fan motor, blown head gasket, cracked head, cracked block. I put these in order of simple to hard and mostly low price to high price.
You didn't say anything about noises but the accessory belt tensioner could be broken and causing the belt to not turn the waterpump sufficiently but you would probably hear the power steering pump growl if that was the problem.
Hope this helps.

Over heating could it be radiator fan motor?


Three quick ideas. Make sure the vehicle sits overnight and check the radiator fluid level
in the radiator itself. If it gets low you will get an air pocket causing overheat. Also check
the reserve tank to be sure it doesn't have a crack or a hose fallen off which would cause an air pocket in the engine block by emptying fluid instead of recirculating. There
should always be fluid in the reserve tank.

Second, radiator cooling fan not coming on. If your air conditioner is not working well at
stop lights, then this is usually the culprit, since the fan helps to move air across the air conditioning coils. Everybody replaces relays but generally it is the motor becoming intermittent, since they are open framed and exposed to the elements.

Third is the thermostat may be stuck in the closed position, which will cause overheat.
Hope this helps.

My heater works but air conditioning won't


The Air-conditioning needs to be re-gassed. Take the car to an Auto Mechanic to get the Air-Conditioning re-gassed. They might also need to check it for leaks to make sure the gas stays in.

Toyota dealer installed a new radiator in my 1994 Camry, and afterward the air conditioning stopped working. What did they do?


they probably had to disconnect the a/c condenser to remove old radiator and failed to reconnect it when the new one was installed. a/c won't work without it. i would make it their problem, it's not your fault. if they also caused your system to lose freon charge they should make that right too. the condenser is a little flat thing in front of the radiator, sort of looks like a radiator itself. refrigerant lines will run from compressor (it's a round belt driven thing mounted to front of engine) to condenser. they either didn't hook it up back up or somehow damaged it is my guess. hope that helps

My car over heats and there is no crack in the radiator no hoses leak whats the problem


1.Could be that the radiator cores are partially plugged. If the antifreeze isn't changed yearly, the sediment buildup can clog those cores. 2.If you bought the car second hand, it could be that the previous owner used some sort of Stop Leak. A really Bad Move, as this junk collects in places it shouldn't, and causes hot spots, (In the engine block, cylinder heads, and so forth),clogged radiator cores, and doesn't always work. I have found unreputable radiator shops who state they have cleaned the radiator out inside it, but just painted the outside, and made it look good. 3.Might be a cracked cylinder head from previously overheating. However, if you're not seeing any apparent coolant loss, and the oil level seems to be overfull,you can rule this one out.

Air conditioning does not function consistently. On very hot days it functions very poorly. I think I've noticed that stop and start in town driving has a negative effect on functioning. It seems to w


check the cooling fans and air flow through radiator,,,,ensure there is no plastic bag stuck over the radiator and look in between the radiator and condenser as those can find their way inside that very small distance between the radiator and a/c condenser. Fans and airflow is a must.
