The short answer to your question: It is unlikely that a water pump will go bad without leaking, but weirder things have happened. Your thinking is right overheating only when you drive is an indication of limited flow, either caused by a restriction (radiator, hose, thermostat), an air bubble, or a bad pump. Are you sure that the air is bled out of your system? If you have an air pocket in your engine or at the pump, you will get reduced flow. I think that the 4.7 Durango has a radiator cap, if so, with the engine cold, take the cap off, fill it, and start the engine. If you get bubbles every time you rev the engine, then you may have a bad head gasket, this would introduce bubbles in the system... Make sure that the lower radiator hose is not collapsing. Most of these hoses have a stiff spring inside to keep them from collapsing when the water pump is running. Otherwise, my guess would be that your pump is bad, or you have more restrictions in your system. Good luck.s
I also own a 2001 Intrepid and recently had a water pump go bad which also broke my timing chain. The pieces of aluminum you found are probably valves or valve springs from the head. Mine broke every vavle and spring on one head when my engine jumped time and a few more on the other head that is probably what your seeing. Also you don't want to check for compression by turning the crank manually. It is an expensive job to fix but the cars are great but I wouldn't spend too much on them because they only go for about $3000-3700 in great condition nowadays. Good Lucks
When the necessary water-pump is replaced 90% of the parts will be removed anyway to access replacement of the timing belt. In other words, the mechanic will have already removed the water-pump and just a few more parts will need to be removed to change the timing belt. If you haven't had the timing belt changed in the past 50,000 -75,000 KM it's wise to have it done now rather than later when the water-pump will have to be removed to change only the belt. If the belt happens to break somewhere down the road it *could raise hell with the valve train and pistons costing more pounds and kilos of money to repair. I only offer this advice as a wise preventative maintenance measure!s
to make it simple what it sound like that they are saying is that the water pump is broken and when this happens in some case one can not turn the pulley of the water pump so the belt would slip on it so long until it overheats and melts leading it to rip. if u don't trust your mechanic have another mechanic look at it and if they tell you the exact same thing chances are they are both right.s
an air bubble and its probable a stable theory to alter the thermostat once you regulate a water pump u would desire to alter the thermostat just to be risk-free that and it in all risk hasent been replaced for a protracted time so chang it i artwork in a keep. yet you're your guy or woman individual so do what you think of you will desire to oks
