idling and overheating

[carview]

Can anyone help me with my Nissan Exalta 2001? Idling drops down resulting in sudden stop. Last November i brought it to Nissan for service unfortunately, problem still occur. Actually, more problems like overheating, unstable hadling + I found a cut tube near the air filter. Could this be the problem for the sudden stop (idling), overheating and unstable hadling??? See picture. Please send me a reply. Thanks!

does you car have a manual tranny? check if the hose leads to the tranny. if that is so then its just the tranny breather. you need not worry about a cut hose.

regarding overheat, look for leaks in the cooling system. then the radiator fans if they're functioning well. check the engine sensors like CTS and Thermistor.

BTW, didn't the nissan casa give you a readout from their CONSULT? if they did then they should clearly tell you if there's a problem with any of the engine sensors.

uu nga. sensors are usually connected sa computer box mo. they can easily give u a copy of the read out of the computer. ur car is kinda smart n e. it usually gives the mechanics information kung what really is the problem of your car. In cases ng overheating check your radiator, fans, pumps, tsaka tubes. overheating is caused by blocked tubes kung saan dumadaan yung water and radiator fluid around the engine, tube leaks, di gumaganang pump n nagpapaikot ng fluids, or fans n di nagcocool ng fluids. taga south k? im connected with a nissan dealer sa south. email me if u want to visit for a consult.

I used to have a Sentra, non-vtec is right, that's a tranny breather. That's normal.

What kind of checkups did they do? A dropping idle shouldn't cause overheating... that's a separate problem... A dropping idle might be caused by an IACV problem or timing issues.

Overheating is complicated. You have to check the water pump, your radiator hoses (what coolant are you using? You should use 50:50), your radiator cap (if it's old, change it... ASAP)... and your radiator. Note that pinhole leaks in your radiator hoses won't show up at idle in the casa... you have to open the engine bay when it's nice and hot and rev the engine and look for the leaks that way.

First of all, thanks for the reply. I dont know what a tranny breather looks like so I took a snap shot where the cut tube leads to. Check out pic below





I also found greese in one of the electrical panel of my car. Could this be the problem of the idling drop down? Is this connected to the cars computer (ECU)? I agree on njgarin computer read out conclusion Problem is, when i brought the car to Nissan they sed its 100% working already. Nissan did the following to my car:

- Check engine performance
- O/H AAC VALVE
- O/H Throttle Chamber
- Clean Spark plug
- Checked all belts
- Performed "consult" test



Overheating. Need to check radiator tubes for leaks and blockages. Ill keep you guys posted. About the water pump, How do i know if its working or not? My water reserve always full. Big chance "water pump" is the problem. Find me a solution. Thanks!

You'll find leaks on the side of the car where the belts are. But if you're not losing water, it's okay.

That's your tranny. And it looks like the tube itself is leaking... better check your level... might be a check valve inside is stuck-up causing a pressure buid-up.
