I have a antifreeze leak on the back side of my 3.5 liter kia sorento motor,I took all the heater hoses loose and they look fine. What else could be leaking coolant the Y that connects the hoses is ok

Hi Kevin.

The general route of coolant will be the engine block, the heater core in/near the dashboard, the radiator, and, often, a coolant overflow reservoir that buffers you from leaks if your coolant gets extra hot or bubbly.

So, along with the heater hoses, there are the radiator hoses, either end. Hose connections to the block. Hose to wherever your coolant check/refill container is. The drain plug at the bottom of the radiator.

There is one other place that coolant can go, though you gotta hope this isn't it. If your head gasket is on it's last legs, coolant can start leaking into your cylinder head. This can show up overtly as white smoke, not so smooth running, or mysterious random moments where a hose suddenly bursts or pops loose. Or it can just be an occasional pinhole leak that's hard to detect.

One of the biggest tells - park the car on a flat smooth surface overnight after you've driven it a while. When you come out the next day, is there coolant on the ground anywhere. if yes, the location can help you track it. if no, then exit through the cylinder head may be the culprit. You'd want to run a compression check to make sure, and then contemplate whether fixing it is worth it on a twelve year old car.

Good Luck!

I need to bypass my heater coil as my aircon is leaking 2003 kia pregio any photos?

Im not quite sure what bypassing heater coil has to do with aircon leak, unless you mean there's coolant leaking from under dash, if coolant is leaking, remove hoses at firewall and follow them back to engine, you can use one of them to bridge from one to the other. Or put a connector between the hoses

2003 kia sorento leaking antifreeze after new radiator

You will want to taste the leak (or get someone else to do so) and make sure it is not water.
Antifreeze has a very sweet taste.
You should only need one drop, and be sure to rinse your mouth out really well afterwards.
Whenever a radiator is replaced, the hoses attached to it can also begin to leak, because the rubber hardens with age, and can be harder to seal again.
I prefer a stainless steel band clamp, not the original equipment.
A good flashlight would be a help as you look for the problem.
Be sure to check the heater hoses, and the other hoses that carry coolant, as any of them could be leaking, due to "being disturbed" or due to the possible higher pressure the new radiator is giving the cooling system.
Be blessed.

How i avoid to the sorento the coolant overheat? i see the coolant leak after use the sorento 2003

Coolant, itself, should not overheat. If your coolant is leaking past the lid of your reservoir, you have overfilled your coolant. Coolant expands when heated. It is important to only fill your coolant when the engine is already cool and to not fill past the fill line. If, however, your coolant is leaking from somewhere else (such as the bottom of the reservoir or the hose as is common with the 2003-2005 models) you will need to have that piece replaced.
