Question about Kia Cars & Trucks
Leaking from under the radiator cap a tube that looks like a lil fan, what is this?
Its the hot water return pipe..but "lil fan"??
Try a new radiator cap..cheaper than a new radiator! Get one from the scrap yard guy first

waterpump houseing/shaft seal is on the way out hence the water/coolant, running along the block. when hot the seal does so, when cold and depressurising seal doesnt.

Highly unlikely that is the case more likely it is the radiator leaking onto the fan. Also check the upper hose to make sure that it doesnt have a pin hole in it. Good luck and dont forget to rate.

That sounds like the heater bypass tube. On the end of the tube going into the water pump is an o-ring. Pull out the tube, clean it real good, put a new o-ring on it. Clean the hole well that it goes in. Then I will put a slight amount of silicone around the o-ring. That helps it go back together and fills any imperfections.
Hope this helps you.

when installing new o-ring on tube, lubricate o-ring and stick it in water pump. Then pull pressure back on tube and then tighten hold down clamp. problem solved

I had the same problem.The leak was from the block heater.I did not notice any leaks on the ground,but was always low on anti freeze.The block heater came apart on the highway and blew all the fluid out of the car,luckly i shut the car off and had it towed to the shop.They replaced the block heater with a rubber frost plug to get me back on the road.Have your block heater checked,they maybe your problem has well.

Physically look in the radiator under the cap for coolant level, and check the valve in the cap for sticking. If air is present in the radiator it can't get out, and more coolant can't get in,(from the overflow). Either clean the cap or replace it and check that it is the CORRECT cap.
Radiator fins dirty, clean with a strong stream of water, not high pressure water.
Radiator clogged, have it boiled out, or replace.
Thermostat stuck open or shut, replace it.
Water pump worn out, can no longer move enough coolant, replace it.
Fan shroud broken or missing....
Electric Fan(s) not working, Check the fan, relay, fuse and engine temperature sensor's.
Belt driven fan, belt slipping, fan clutch is bad, fan blades have flattened out.
Air dam under front bumper is gone, loose, or broken. It actually has a purpose other than scraping on the driveway or curbs. It forces air up into and thru the condenser and radiator. If it
