I have a 2005 nissan altima 2.5L with 140,000+ the engine rattles when start, when i pass 40 mph the engine rattles more and the temp gauge increasing but there no way my engine should over heat, also while waiting at a stop sign or stop light the engine sometimes cut off and solutions on what i need to get repaired

SOURCE: No heat when engine is at low rpm or idle.

same problem with my 2005 Altima V6, with only 44k miles on it!!! and this is the second winter in the last 4 years that I have to pay for a coolant flush to fix the problem. This time the thermostat is getting replaced too. Time for a new car!

SOURCE: 2005 Nissan Altima makes rattling/vibration noise

It is possible that you have some timing chain noise, especially if you have the 3.5L engine. The secondary timing chain tensioners on the 3.5 have a known problem, Nissan has issued a service bulletin regarding this and there is an updated part to replace them. It is not a cheap job, but your dealer may give you some "goodwill" depending on your mileage. If you have the 2.5L the problem may a couple of other things...even more serious! They had catalytic converters that came apart and got ingested into the engine, eventually destroying it. Try googling "Altima rattle" and include your engine size in the search. There is a ton of info on the net about noises in these cars.

SOURCE: 2005 Nissan Altima cuts off while driving.

Dear Tajack73: Nissan had a voluntary recall campaign on the 2002,2005,2006 Altima's with the 2.5 litre engines It envolves reprogramming the ECM.
The campaign ID # RD0712 NHTSA #: 07V-527
2005 Altima Vin's 1N4AL11**5C 100003-957025
1N4AL11**5N 400000-934180

The symptom you have described fits the one they have describe in the bulletin. Check with Nissan and see if your car falls within the campaign. Let men know how you do.

SOURCE: Engine sound humming low and high

If the engine is overheating, that's why the light is on. Its a P0271 code I beleive. Its a "OVERHEATING" code.Dont drive the car. You are loosing coolant or its out of coolant, check the coolant level in the overflow bottle. We have seen some headgasket issues on that model car. I would remove the spark plugs and look into the cylinder for any signs of coolant on top of the pistons. Let me know what you find.

SOURCE: 2001 Nissan Altima - Instrument panels gauges stop working

My 2001 Altima's instrument gauges die out after high-speed driving for 40-50 miles. Engen also loses power. Everything is back to normal when the car cools down. It turned out the ingition relay was bad. I could duplicate the problem right away by removing the relay. Actually, it is very easy to find the relay which is located above the fuse panel. The ignition relay is the bottom left one among the five relays there. It costs only $20.
