How can you tell your a/c is ready to replace it`s coolant gas? My 2007 elantra particularly on a hot day doesn`t send cold cold air at the coldest level indicator It is cool but would that indicate the coolant being low as this car was used previously on leases and was bought 2nf hand!

To tell if the ac coolant requires replacement the car will not cool when the sun is out and at all time you might have to put the car ac in coolest to enable a little bit of cold air.

Also the back seat will not be cool except the car is running on the highway.

Gas might be leaking somewhere.

Good luck

HOT AND COLD


Sounds like you have an air lock in the heater, needs bleeding. From cold check and top up coolant, run engine without coolant cap put heater control to hot, watch the fluid level, will rise then fall suddenly when the thermostat opens, top up coolant and put the cap back on, later when the engine has cooled down again, check coolant level. Hope this helps.

My 2007 Chevy HHR 2.2L, coolant temp sensor is reading that the coolant temp is 20 degrees warmer than the outside temp after sitting for over 12 hours and the operating temp gets to 214 degrees without...


Sure the engine coolant will be warmer than the outside temperture and if the car has been sitting a long time in cold weather and the outside temperture warms up it could be the other way around. The coolant temperture sensers aren't real accurate as they are a relaitive senser beween hot and cold and the numbers reported don't have to be real just the change from hot to cold and the reching of the coolant to the operating temperture. Noe it the senser doesn't read the opertating temperture coprrectly you'll have all kinds of problems. The therostaste will try to set the temperture of the water to it's set temperture and can open or close completly to get 195 degrees F. Many times if it's too cold then the stat is bad and needs to be replaced This shows up in alot of cars first thing after winter and the first onset of cold weather when the daily tempertures vary the most from day to night.

My 2005 hyundai elantra wont start


Sounds to me like your charging system failed and you now have a dead battery.
You will likely need to replace your alternator.

Heater blows warm/cool air


Isn't it suppose to?

Are you trying to say the warm air isn't warm enough as it used to blow?

When is the last time you has your radiator coolant flushed and replaced with new water coolant mix?

When the vehicle is cold NEVER WHEN HOT unless you want boiling hot water to scald you. Open the radiator cap and check the coolant for smell, thickness (it should not be, it should be of water consistency) and the color should not be rusty color or you may need a flush AND you may have a sticking thermostat that needs to be replaced. This is a fairly cheap item and easy to replace, should be an inexpensive fix even at an auto shop if you can't do it.

Is the air being directed to the vents you are choosing?

We have been experiencing some of the coldest weather of the decade lately. I'm not sure if your particular vehicle has an air compartment recirculation selection option on your heater/fan controls. If you do, I would select this option and it would make the air much warmer on colder days and heats up quicker as it reheats the air already in the passenger compartment vs pulling in fresh air to reheat from scratch.

It the same as boiling a pot of water, letting it slightly cool then turning the heat back on causing it to boil quicker vs dumping out the water and refilling it with cold water and trying to get it to a boil.

Fluctuating engine temp a/c sends out cold air intermittently


Here's the thing. The ECU will shut down AC if the engine temperature is too hot. If the coolant temperature sensor is malfunctioning (lying to the ECU) telling it that the temperature is hotter than it actually is, the computer will turn the AC OFF.

Air Conditioning Not Cold!


Get someone to re-gas it with a dye and see if it's leaking. Check the compressor.

2000 Elantra Overheating


First when vehicle is cold like in the morning check and make sure that the vehicle has enough coolant/ antifreeze in radiator and reservoir. If coolant is need use a 50/50 mixture of water and antifreeze. You will need some time to do this let car run at idle until the temp guage is in the middle NOT+ normal operating temperature. At this point if the thermostat should be in the open position. Let vehicle run and check to make sure that radiator fan comes on. This should come on when guage is about midway/half way. If temperature rises above half going to h/hot and fan doesn't come on, you either have a BAD FAN BAD FAN SWITCH BAD FAN RELAY OR BLOWN FAN SWITCH FUSE. You will need to check all of the following I will help if its needed. If fan comes on and doesn't go off and vehicle continues to get hot even with fan running. Feel radiator hoses and see if the lower radiator hose is cool/cold. If it is you have thermostat that stuck closed. Replace thermostat and fix problem. If all the above is good and vehicle continues to over heat. THE BAD NEW IS THAT YOU MAY HAVE A BLOWN HEAD GASKET /CRACKED HEAD /BROKEN WATER JACKET. Basically you will need a HEAD JOB at least a head gasket. ONe tell tail sign of this is oil looking like milkshake/chocolate milk-a creamish while residue in oil or antifreeze. Contact if you need hel0p. Good Luck and thanks for using FIX YA

If this car is remote start GM has a service bulletin out to do a computer flash to correct this problem, it will probably blow hot air in the summer if it remote started if you don't have the computer flash done. Hope this helps
