Question about 2007 Kia K2700 Workhorse
Changed fan clutch and radiator
Posted by Anonymous on
Could be a number of things, 1. water pump not working 2. Thermostat stuck (replace if its boiled) 3. air lock in system. 4. Head gasket. 5. cracked head/block. I presume you have checked that you belt is not broken, are there any signs of leaking around the waterpump? if there are, change the pump, If the engine has overheated, change the thermostat. these are the most common things, other than these 2 it is going to take further examination for cylinder head problems or blocked water ways. Go for the thermostat first, its probably the cheapest part to replace, and see if that cures your problem.

To start with you have to do this:
With the engine cold, start the car and say after 30 to 40 secs. open the radiator cap.
Carefully and slowly, cause if the problem is either in the cylinder block or cylinder head this shows immediately as water would be compressed in the radiator ( even though the motor is still cold ).
If nothing happens and you would not notice any bubbles in the radiator, then we have to talk again.

There should be a electric fan. Watch your temperature while it runs and when it gets up to around operating temperature the fan should kick in and run.

Did you install a new thermostat and make sure to bleed all the air out of the system when you replaced the radiator? If you didn't, or installed a Stant thermostat, replace it with a FACTORY OEM thermostat. Make sure the cooling system is bled by opening your radiator cap (WHILE THE CAR IS OFF AND COLD), starting the car and running the heater. Add coolant to the radiator as the engine heats up, until is at normal operating temperature AND starts spitting coolant back out.
Hope this helps,

Not sure if you know, but there are TWO fans...one for the a/c cooler (front) and one for the radiator (rear). I have the exact same car with similar issues with minor overheating, and from my observation, the actual cooling fan for the radiator is mounted on a pulley directly behind the radiator, and I haven't located any type of electrical wiring for this particular fan.
From info I gathered at different forums, this fan appears to be engaged by some type of clutch, I suppose similar to that of an a/c compressor. However, I haven't been able to gather much info as to how the fan actually "operates", such as how does it know when to engage and disengage, and whether or not this signal is mechanical (physical), or perhaps some type of built-in sensor (electrical).
I haven't been able to look at any type of diagrams or schematics, so I can't say with 100% certainty that there isn't wiring for this fan, but so far it appears that replacing the clutch assembly, or perhaps the entire fan with the clutch assembly, appears to be the fix for this problem. I haven't been able to apply this action to see if it is a definitive fix because I'm currently having issues getting my 2000 sportage to start. But if you still haven't come up with a corrective action, I'll be sure to keep you posted once she's running again.
