Your local mechanic should have a tester that can tell you. It uses a chemical that will change color if exhaust gases are present in the coolant. Very cheap to check- should charge you for 15-30 minutes.

SOURCE: oil change procedure on a 2005 Hyundai elantra

it is very easy to change the oil put the car on ramps secure the back end look for the drain plug underneath the engine make sure you have the right size wrench and when you remove the plug also check the gasket on the plug to make sure it is not cracked you will also need an oil filter wrench and my other suggestion to you is to go to autozone to see if they have a Haynes repair manual for your car and if they don't see if they can order you one in the mean time they can also print you off a diagram of how to change the oil in you car safely

SOURCE: How do I add coolant to the air conditioning

You need to locate the low port on the AC.

You recharge the AC connecting to the low port.

You find the AC low pressure at the top of the compressor. Near the compressor you find two ports, the high port and low port.
You can follow the compressor line to reach the port.

To find out which one is the low port, run the air conditioner for a couple of minutes withthe engine on.
Then turn off the care and touch the lines from compressor to the two ports , often covered with plastic caps. Only one of the pipes will be cold, the line that is cold will lead you to the low port.

2001 hyundai elantra heater only blows cold air,it overheats within a block of driving then car wont start for a couple hours what is the problem


Blocked cooling system most likely a stuck thermostat. The coolant is not circulation therefore not getting to heater core. Replace thermostat and it should be fixed

Wait till the engine is cold, remove the radiator cap, start engine and look for coolant gushing out of radiator or a lot of bubbles, its possible you have a blown head gasket.

Car overheating we changed the thrermostat still the same


Check your overflow bottle for any signs of exhaust fumes, the coolant for any signs of oil contamination and the oil for any signs of an emulsion forming. Overheating is often a sign of a blown headgasket with a leak between one (or more) of the cylinders and the coolant passage in the head and block. If ignored, when the oil looses too much of its lubricating value due to water mixed with it, the engine can seize up and then it gets very expensive.
If you want to embark on doing your own maintenance, I highly recommend you invest $20 US in a Haynes manual for your car which will contain all of the info you need on things you can do at home.

Pushing anti-freeze out the resevoir. Changed water pump, thermostat. Temp. gauge does not indicate overheating. Fans seem to be working OK.


Try replacing the radiator cap. A weak cap will allow coolant to leave the radiator and go thru the overflow tube to the reservoir.

2000 elantra has creamish residue arround oil cap but i have no problem with the vehicle''


It's from moisture. If you only do short trips....but, make sure your coolant is staying full, that you aren't getting coolant in the engine oil.
If that's ok, you should be fine.

Where is termostat in hyundai elantra


It is not likely the thermostat, because the thermostat is showing that it is overheating,so it is working, you must have a coolant leak somewhere. You will have to find coolant leak. Car is overheating because it is low on coolant

Overheating


Should just be the two bolts holding the metal cover on. Follow the top radiator hose if you aren't sure where it is.

Before you do this, make sure you check your coolant level to make sure it isn't just low.

Hope this helps.

Overheating, don't know why


The most common problem with overheating is the thermostat. It becomes plugged and won't allow enough coolant to pass through the system. Another cause could be old coolant. Flushing the coolant periodically (when the coolant appears to have rust in it or has faded in color) is a good idea to keep the antifreeze/coolant up to peak levels. Bost are worth looking into but I'd be surprised (barring any leaks in the sytem) if the thermostat wasn't the culprit here. Best of luck.
