Hi!!

When your vehicle motor overheats, it looses power starts making a rattling noise and eventually dies.

If your vehicle was not driven too long after engine started overheating, Check motor oil, if it looks normal, add water or cooling fluid to the radiator or reservoir tank and sart it up, if no noise, this means you are saved, take car to closest autoshop and get it fixed ASAP. If shop is too far, have it towed.

In the other hand, if the oil looks milky or your hear a knocking or rattling noise after adding coolant to your system, your engine will need an overhaul.

Apreciate if rate this post, GOOD LUCK!!

With the car cold for a few hours, take off the cap on the coolant tank and look at it, it should be clean and red. If it's not, or looks 'oil slicky' you may have a coolant leak into your oil. You can also drain the oil to see this, the oil should look like regular black oil, if it's bubbly, foamy or even light tan/brown you most likely have a blown head gasket or upper intake gasket.

98 continental replaced cooling system still over heating no heat till it makes a rattling noise from behind the dash then throws heat can't see where coolant is leaking


You do have a coolant leak, coolant is on the ground under the car then? The noise you describe is from a badly overheated engine. I think you have blown head gaskets

What is the rattling noise i hear when i accelarate in my cadillac deville. 1995


Check your oil. If oil is too low, it makes a rattling noise in acceleration. Also, be careful that it isn't your timing chain. The timing chain, once it's starting to fail, will make that noise as well.

My Audi A4 2009 makes a rattling noise on cold starts which resolves in less than 30 seconds. Dealer says its an air pump. This doesn't seem correct. The noise comes from the front of the care. Does not...


READ THIS (happy ending so far...):
audi a4 2L turbo quattro, manual transmission with 98,000 KM. Perfect conditions, no oil leaks whatsoever.

Left the car off for two weeks in very cold weather (-10C down to -25C). When I restarted, it started immediately but with heavy rattling noise due to camshaft adjuster not getting enough oil pressure. After 3 minutes of warming up (outside temp.: -12C) at very low rpm (below 2,000rpm), I start moving the car. Still hearing heavy rattle noise. As soon as I pass 2,000 rpm, I get a scary red warning, low oil pressure. Turn off the engine immediately. In 1 minute, I re-start the car and the engine lights check ok, so I drive in first gear super slow (1,200rpm) hearing the same rattling noise. After another minute, finally the noise all the sudden disappears and the car starts running just fine.

Called Audi dealer and they told me that in extreme weather conditions, I should warm the engine for 10-15 minutes if necessary before start moving.
Take away: luckily, I didn't screw up the engine since I was using it at extremely low rpm (easy to do with clutch and manual transmission) until the oil reached full pressure. I am pretty sure now that the problem was leaving the car off for such a long time in freezing weather. All the oil flows back to the bottom, and when I restarted it, the cold oil with high viscosity took a long time to reach all the parts of the engine, specially the camshaft adjusters that are actuated by using oil pressure. Next day, the car started at -9C perfectly without making any noise (as usual). Basically, the longer you leave your audi in cold weather, the longer you might hear the rattling noise until the oil reach full pressure inside the engine. My car took 6 minutes to fix it after couple of weeks in cold weather. This makes sense to me; in fact, in the past I only heard the rattling noise after leaving the car off for a couple of days in the winter.
So far, this has had an happy ending....

Driving on freeway, engine made rattling noise and wouldn't excellerate any longer. Smells like it got hot, but temp gauge didn't register that it was overheated. Coolent reservoir is dry. Don't know if...


If the coolant reservior is dry you need to open up the radiator cap when the car cools down and see if there is coolant in there. If it is empty, turn on car first and then fill up with a 50/50 mix of coolant and water. Once it is full and you see the coolant circulating put the cap back on and add the mix to the reservior to the cold mark.

Did you check to see if your car has oil in it too?

Car makes strange sound when slowing down


Happens on rough road or bumps? Grab a hold of your sway bar links fronts and rears, should be tight, no play. These things sound like metal to metal tapping, very common. Get a replacement link that has a greaseable fitting. Easy easy DIY.
