Question about 2001 Kia Optima

1 Answer

2002 Kia Optima has a knocking sound until the engine heats up and then smells like an overheated engine, lots of clicking noises after you turn it off. Checked the antifreeze level, at the top, there is turbulence while running. Gauge stays between the dots for safe temperature. Pretty sure it isn't the thermostat but haven't ruled it out yet. Any ideas why this happening?

It's possible that your oil level is low or it's time for an oil filter change.
If not, it's possible that the rockers need adjustment, but I doubt it. Good luck

Engine lock up


You lost oil pressure, either due to oil loss or oil pump failure. When this happens the crankshaft bearings lose lubrication, heat up, expand, and freeze, or seize the engine. This is called lockup. The Kia folks lied to you about the safety of driving in this condition, or they didn't understand your description of it. Loud knocking inside the engine calls for immediate shutdown to avoid catastrophic damage. You are now looking at at least and engine rebuild, if not a full replacement.

engine running too hot.check coolant level, should be 50/50 antifreeze and water.replace thermostat and radiator pressure cap.check antifreeze level in the radiator,coolant level should be just below radiator cap, add coolant to overflow jug,should alway be at the full cold mark.empty coolant overflow jug will allow air be drawed in the coolant system causing overheating.if overheating happens when coming to a long stop.could have faulty engine coolant temperature sensor or bad coolant fan fuse or relay.

Adjust radiator cooling fan 2003 kia optima


There is no adjustment on the cooling fan. If the car overheats, there are only a few things it could be. First, with the engine off and cool, check if the radiator is full of coolant and it looks clean.

The most likely cause of overheating is a stuck thermostat. You will need to drain the coolant and replace the thermostat. You can locate it easily by following the top radiator hose to the housing on the engine. The thermostat is under this housing.

You could also have some kind of blockage on your radiator. If there is a lot of dirt in the fins, air cannot circulate and remove the heat. Use some compressed air to blow the fins clean.

Kia 2.4 optima 07 engine makes knocking noise when I press fuel pad to move..I can't press fuel pad strongly the knocking noise increases more and may broken the rings


Sound like you have spun a bearing do to a blown head gasket. Does the oil on the dipstick look almost like a chocolate milkshake in color? If so your coolant has reached the oil pan and that can definitely cause the engine to spin a bearing causing a loud knocking sound.

Kia Optima 2005, Engine gets over heated in slow speed, but cools down to normal in speed around 40 miles per hour. This is due for 60K miles service. what could be the issue


You have a problem with the rad fan. This could be a fuse, wiring, an so on. Do Not drive this car until this is corrected!! Overheating a car is like a person having a stroke! Some come back, others don't.

2002 kia optima,,, whining noise that stops when turning left


power steering pump probably went out.. if you can easily get at the belt and are any kind of mechanically inclined, remove the drive belt to the p/s pump and then start the car if the noise is gone then its probably part of the power steering pump

Change belts on 2002 kia optima


Not sure what engine you have , but I had an 02 rio with the 1.5 L . The serpentine belt did not have a tensioner (spring loaded) pulley , the belt tightness was adjusted by pivoting the alternator mount.
If you are takling about the Timing belt , the tensioner pulley wont move (even though it is on a spring ) untill you loosen the bolt in the center.
