The speed control of your fan has resisters that are in the venting system to blow air on them to keep them cool. If they overheat and or burn you will lose your low and medium speeds of the fan. If you run the fan at full see if the smell goes away. Your engine could be burning oil on the outside of the engine block, make sure that the weatherstrip where your hood meets the fresh air intake grill is sealing tight.

SOURCE: Nissan Sentra 2000 model. Thick White smoke coming out of exhaust

White smoke is caused by coolant or water coming out the tail pipe. There is a chance that the white smoke was caused by water splashing up from a puddle onto the exhaust pipe. Keep an eye on the coolant level in the radiator in any event.

Let us know how it goes or if the problem persists. We're looking forward to how things go for you.

You will need a new catalytic convertor assembly. Yours is below treshold efficiency in other words its "no good".If you have it replaced, ask the garage/dealer to give you the old one back. Its worth some cash if its full. It doesn't matter thet it failed. They are going after the mesh inside of it and that is worth some $$$$. May not be much , but better than nothing.

If exhaust white smoke out huge what part is defective in nissan sentra sr e?


if the weather is cold enough it will have white smoke coming out the exhaust it just indicates the moisture that is the by product of combustion and as the engine gets to operating temp it should diminish. if it smells sweet it indicates that the engine is burning coolant.

Your right something is very wrong & it is afire hazard. The fuel system is under high pressure so it may be a small leak (just in the wrong spot -AC) get that fixed. usually just fuel lines. Good luck........but don't drive it until repaired

Nissan Sentra 2000 model. Thick White smoke coming out of exhaust


Is the car runnig little rough on cold start up in themorning for few seconds?? Because I have done quite a few headgaskets on QG18 Sentra aka 1.8 liter nissan sentra. here is the test. Fill up your overflow bottle to the full mark and check the coolant level in about 5 days.(drive it normally as if nothing is going on) If the level is down, your head gasket is gone. How about the check engine light , is it on?? post results.
