When engine is running there is more pressure on hose you have to have a pin hole in hose. you better replace right away because if you don't and the car over heats you will possibly blow your head gaskets causing water to get into your oil and costing you a small fortune. replace hose right away and make sure you have plenty of engine coolant in your vehicle.

How do I fix this coolant leak?


This could be a hose or a radiator leak.

And antifreeze is supposed to be bright green or pink for a car of that age. Brown is never a good color for antifreeze--it means car was run with too little antifreeze for a significant period of time and the block and water pump has rusted internally. This is not a threat to the engine block, but it will kill the water pump eventually.

Find the leak, and take appropriate action--if it's a hose, you can replace that yourself and save $. If it's the radiator or even heater core (not likely), it's a trip to the shop for sure, unless you are able to handle the degree of difficulty that goes along with replacing a radiator (about 6-7 on a 10-scale, and usually a major hassle). A radiator shop can fix the leak, saving you new radiator $.

How to replace thermostat on 2005 hyundai sonata 4 cylinder


selectcategory1.gif Thermostat ABCDEFGHIJKLMNOPQRSTUVWXYZ Test/Replace

CAUTION
If the radiator is filled to the top with coolant and the engine is run without the radiator cap in place, the coolant will expand and spill over as the engine warms up.

  • Drain some coolant into a clean container until the coolant level is below the thermostat housing.
  • Remove the upper radiator hose connection from the thermostat housing.
  • Loosen the housing bolts and remove the housing.
  • Remove the gasket and scrape it carefully from the surface of the housing and the mounting surface on the engine. If the gasket remains on either of the surfaces, there will probably bea coolant leak after reassembly. Some engines use a rubber O-ring to seal a thermostat housing.
  • Compare the size of the thermostat to the old one. They are of different sizes, types, and temperature ratings.
  • The temperature rating is stamped on the sensing bulb on the bottom of the thermostat. The temperature bulb faces the block.
  • When replacing a thermostat, be sure that the thermostat fits into the groove in the block or outlet housing. If the thermostat is installed upside down, the engine will overheat.
  • Install the gasket.
  • Reinstall the thermostat housing. Refill the system and run the engine or pressure test to check for leaks.
  • When the engine has reached operating temperature make sure the thermostat opens.
  • You should be able to see coolant circulating within the radiator.
  • Another way of checking thermostat operation is to feel the top of the radiator hose or use a thermometer or multimeter with a temperature probe to confirm that the coolant is warming up.
  • If the engine is overheating, but the top hose is still cool to the touch, the thermostat is stuck closed and must be replaced.
NOTE When a paper gasket is used and the recess is in the thermostat housing, it is a good practice to position the thermostat into the recess and glue the gasket to hold it in place. If it falls out of its groove during installation, the outlet housing can be cracked or a coolant leak will result. Before tightening the water outlet housing, try to rock it back and forth to be sure it is flush. Housings are often cracked during this step.

Leak in the radiator hose lower one should i do anything else after changing the hose


1. Turn on the heater controls. Remove the bottom R/ hose entirely and then remove the top R/hose from the radiator end. (If the top hose has not been replaced previously (or recently) then replace it with a new one as well). Then flush the cooling system.

2. Reconnect the new hoses and refill with the correct spec coolant as stipulated by the manufacturer. Do not use anything other than the coolant type/mix specified by the manufacturer. Start the engine and continue to refill the radiator as the level drops. Check and re-check the coolant levels. Make sure you check the overflow reservoir and top up to the coirrect level.

3. You will need to bleed air from the cooling system because air will be trapped and the cooling system will not operate properly with air in it. If you do not know the correct procedure for doing this on your model you will need to have it done by a competent mechanic familair with your vehicle.
Failure the bleed air from the system will result in the engine overheating, due to air locks in the cooling system, and possible expensive engine damage.

My 2002 hyundai sonata, help:)


cold weather won't usually hurt anything in your heater, it will just take longer to warm up the cabin.

the lack of heat is a sign that you're probably not getting the proper circulation in your cooling system, that is, the radiator, anti-feeze/coolant, fan, etc.

bad circulation means your anti-freeze level could be low from a leak, or a hose that popped off. or you could have a bad water pump, which is what circulates the coolant through the engine and radiator, even though we don't use water anymore.

the solution is to have someone who knows how check the thermostat, radiator, coolant level, hoses, and water pump to make sure everything is working.

be sure to address the problem soon, because if it's a coolant system problem, the more your drive, the more damage your engien will suffer.
