It could be the valve lash, try an oil change.

I have a 2009 Nissan Altima and when I stop I hear a pinging noise from engine but when I accelerate it goes away. When I put it in park the noise goes away. It only happens when I am stopped at a light...


Take to a mechanic. My guess is you have either a hydraulic valve lifter problem or if the car has not been properly maintained you could have signs of engine bearing problems. Double-check your Engine oil level immediately. If it is low or not even on the dipstick, hopefully that is the problem and you have caught the problem early enough. Good luckl

03 nissan altima high pitch whine from engine


I assume that you have a 6cyl engine, noise came from both worned secondary timing chain tenssioner shoes, just replace those two and while you have them all apart, also replace main tenssioner and guide, then all noises will go away. Good luck!

1998 Nissan Altima GXE squealing noise


Could be the bearings in your alternator have gone dry and your alternator is about to quit out on you. I had a friend with an 01 altima and we could always hear him coming before we saw him because of this very problem. Changed the alternator out and noise went away. Thanks for using FixYa!

I have an 03 nissan altima engine makes loud clicking noise


1st check the the oil level and the vehicle's oil type.(owners manuel) 5w30-10w30
10w 30 is a thicker oil and could possibly be causing this.(Moves more freely through the engine heats the oil)

Loud air intake engine noise on startup


I would guess it is the electronic fan clutch. It will cause the fan to run too fast (very loud) and the light will come on sometimes.

Heat not working or diles


You most likely have an air pocket in the cooling system. The heater core on these vans is much higher than the engine and they can be tough to get all the air out of them.

Make sure the coolant in the radiator is full when engine is cold- also fill the overflow bottle to the top. Chock the rear wheels. Jack up the front of the van as far as you can and support with jack stands. Run the engine until it's warm and then hold the RPMS at 2000 for about 5 minutes while checking for heat inside the cabin. You may hear some funny noises like something is trying to come through the firewall forcefully! That's the air pocket moving... you might not hear this also. Once you have good heat inside, let the engine idle- if the air coming form the vents cools off after a couple minutes, the air is still there- keep doing this until the air is hot coming from the vents at idle for more than a couple minutes. Once you have good heat, turn the engine off and let the engine cool completely- at least a couple hours... you will most likely see the level in the overflow drop dramatically. Lower vehicle and make sure overflow is at COLD FULL mark.

Newer Altimas also had a similar situation in which heat would go away at idle- usually not a problem with an air pocket, but Nissan has a bulletin out on putting the correct concentration of coolant/water in the system- these cars are very sensitive to changes in coolant mixture concentration.

Noise when car is started


Sounds like the starter stays "sticked"on... Check the starter relay or after the sound goes away touch the starter for heat. If its too hot it means it stays on working even when the engine is allready running...
