My car overheated instantly and then it had a grinding sound when i tired to start it. It will start at all. Could a bad water pump cause it not to start? Or, what's the problem and how do I fix it?
My car instantly overheated today, and as I was pulling over, it died. When I lifted the hood it was smoking over by the belts and water pump. When i tried to start it, it made a bad grinding noise. I got it towed back to my house and now it wont start at all. It's not the started because we got to start for a second, but then it died again right away. If the water pump went out, would that cause it not to start? Or what is the problem and what do I do about it?

The waterpump may have went out, leaked out all the coolant, and depending on how badly you overheated your engine, you may have serious problems as to some engines dont handle extreme heat very well. you might want to get professional help

I can't explain why water in the engine means bad water pump, but... Overheating can certainly be caused by a bad water pump. Water in the cylinders or in the oil after overheating is typically caused by a blown head gasket, and you can't really fix that with a water pump.
I think your mechanic either needs to do more checking, or is trying to get you to do an inexpensive task, so he can discover an expensive one while he has it apart, and you can't take it somewhere else.
The 3800's also had other problems. And also Issues for those that are unaware.
Be aware that there are bleeder screws to bleed air out of the system when filling the coolant. With out properly bleeding the system the coolant can Vaporlock in the system causing overheating.
Also if it has been over heated you need to check for a blown head gasket. Smell the antifreeze, if it smells burnt you should be concerned. Next with the engine cold and the system properly bled, leave the radiator cap off and start the engine, if it bubbles constantly or bursts out of the open radiator cap, seek diagnosis at your local repair shop as they have the equipment to do so properly.
I also suggest using an Infrared Thermometer to check temperatures with. if the engine is at 230f and the upper hose is at 200f, and the lower hose is still cool you likely have a clogged radiator. If the upper hose is cool as well then you have a bad water pump or t-stat. if the upper hose slowly warms, and you start to get bubbles then it's likely a water pump with the fins eroded off by electrolysis (gotta change that coolant at regular intervals)
If you have the 2.7L engine, you may have a bad water pump. The water pump is turned by the timing chain. When the water pump on those particular engines go out, tension on the chain goes away and retards the camshafts bad enough for it not wanting to start. Pull your oil dipstick out and see if you see signs of water in the oil. If there is, this is your problem. When the water pump goes out on those engines, it'll drain water straight into the front of the oil pan.
if your sure the cooling system is full than i wouldn't be surprised if you had a head gasket that has failed.
This would explain the water noise, and overheating.
With the engine cold remove the radiator cap, start the vehicle and let it idle. continue to monitor the coolant level in the radiator. top it off if it gets low. If you see a constant perculation of air bubbles coming out of the radiator than the head gasket is bad.
Sometimes you can also smell the radiator or the overflow. If it smells like exhaust than the head gasket is leaking.
the grinding noise sounds like the axle shaft joints are no good and need replacing.also the wheel bearings could be so bad that they are causing this problem.i have seen where badly worn out brakes have made a grinding noise on turns.the tire squealing i don`t think is related to the grinding noise.check out the other things just in case it is changing the tire angle which could cause squealing.
Overheating is not always caused by a bad water pump or bad engine firing timing.
The most common causes are:
faulty radiator cap: steam/water will be escaping from the caps when engine is hot or oveflow tank overflows or empty!
crack cylinder head gasket: check when engine is cold thru radiator cap hole for milky oil in water radiator or large bubbles in radiator water after starting engine. Also check if water steam comes out of exhaust.
cylinder head itself: same symtoms as for gasket above.
Timing - engine is not sounding right or back firing. Head gasket - water and oil mixing, see inside water bottle. or open bottle. rev engine when cold, if starts spitting water out while cold like a fountain. Water pump - Water leaking from side of engine. or when car started and water bottle is open and no circulation is visible could be signs of water pump Remember - Block radiator lines can also cause over heating problems and lack of water circulation.
SOUND LIKE BLOWED HEAD GASKET.BUT WAIT TO SEE IF ENGINE WILL CRANK WHEN ENGINE COOL DOWN.MOST CARS PCM WILL SHUT CAR DOWN TO KEEP FROM DAMAGING THE ENGINE.CHECK FOR LOW COOLANT.YOUR OVERHEATING PROBLEM COULD BE CAUSED BY BAD THERMOSTAT OR WATER PUMP.CHECK PUMP WEEP HOLE TO SEE IF LEAKING.IF YES REPLACE WATER PUMP.
it could be a bad water pump if you hear grinding the serpentine belt wraps around the pump and pump has bearing's that are possible went out this means bad water-pump if have changed convert coolant, instead of dex-cool use regular green coolant the dex-cool is a lemon on any gm motors that use it. you may even see if genarl motors will fix problem with vehicle. I hope this was helpful please rate this and thank you!!!
