Question about 2003 Pontiac Grand Prix

1 Answer

I have a 2003 pontiac grand prix and i noticed white smoke coming from the hood. I've also noticed a squeeling noise while driving. I was wondering if this has anything to do with the belt?

It seems like something could be leaking but we are unsure of what it could be.

SOURCE: the coolant leaked right out onto the ground, the pump is working

there is an overflow tube for the coolant resovoir. if the vehicle is running fine, no busted hoses or radiator, and not overheating then probably you just put too much coolant in. keep driving it and keep an eye on the coolant levels and temperature. if those remain ok then you should have nothing to worry about

  • Make sure your new belt exactly matches the old belt demensions
  • Take a breaker bar or big rachet & release the tension on the automatic tensioner; very slowly
  • Loop the old belt around the pulleys & fan
  • Install new

SOURCE: Squeal under hood 2000 Pontiac Grand Prix GT (3.8 L)

I would start with a belt. While removing it feel how much tension the tensioner has on it, on the 3800 egnine they have a stiff tensioner(sorry I don't have any specs for how much) After you get the belt off you can look at all of the pulleys and spin them to see if the bind or look for stuff stuck in the grooves on the pulleys.
It sounds to me like the belt is streched. I would not recommend one of those gator back belts, they seem to make more noise sooner than a good v notch belt. But thats just my opinion!

SOURCE: 2004 pontiac grand prix 71000 milesis burning oil.

How many miles do you go before you have to add oil. GM actually states that one quart of oil every 2000 miles is considered normal. I personally think that one quart every 3000 miles is normal esp at higher miles. As an engine wears things such as valve seals and rings get worn and allow oil to seep past and will burn, this can be in such small amounts that you will not notice the smoke and is normal engine wear. The life cycle of an engine is considered 100k miles by the designers, even though we all know they will go far beyond that. If your car has the 3.1 or the 3.4 liter engine you may want to check in the engine coolant for signs of oil, it is a common problem for the oil to seep into the cooling system but is not usually enough to make a noticable drop in oil level. If you are only using about one qt every 3k miles or so i would not worry about it if you have had it checked for leaks already.

I have a 2004 pontiac grand prix with white smoke coming from underneath the hood and tailpipe.


Sounds like you've got a coolant leak. Check the condition of your radiator cap (look for deteriorated rubber, etc). You'll probably also need to top your coolant system off as well. It would help you if you pop the hood before starting the car, start the car and then watch the engine compartment so you can identify where the white smoke is coming from so you'll know what needs repair. No need to be a master mechanic to open a hood and watch an engine for 10-15 minutes...
Also as a last resort if you're having overheating issues but need to drive in an emergency you can turn your heater on full-blast... the heater can act as a supplemental radiator (useful for when the engine fan fails), just turn it to max hot and max fan and roll the windows down as necessary. Turning off the AC and extra electrical accessories helps as well because it puts less strain on the engine accessories, which put additional strain on the motor as it tries to provide power to everything.

2004 pontaic grand prix white smoke coming fro m exhast


Quit driving it. You have blown a intake manifold gasket or a head gasket. 3.4 engines are known for blowing intake gaskets. Check your oil, make sure it is not exessive or milky in color. White smoke is caused from water/coolant entering the cylinder.

These vehicles are known to have power steering issues. They use up fluid and at about a 100k or so the pulley itself can "sheer" right off. I would check your power steering fluid level and go from there.
