water pump (has a pin hole overflow if goes bad) , water hose connection, overheating, damage to the radiator causing a crack?
Water in the floor of your Dakota can mean two things. Your heater core is leaking in which case you need to keep check of the radiator fluid because your truck will overheat from lose of fluid or the drain hose that leaks condenced water to the outside when you run the A/C has come lose or is clogged
coolant in engine enters radiator at the bottom, goes up thru radiator and exits radiator at top. i would think your radiator is clogged up try a good,(expensive) radiator flush to see it that fixes proble,
I assume you want to change out the water pump and would like to know if you can do it without draining the radiator. You will lose approximately all the coolant in the radiator reservoir when you remove the radiator hose from the water pump. If the coolant is in good, clean condition, it might be wise to drain the radiator into a container and re-use the coolant.
The most common reason for overheating of a car radiator is that there is not enough water in the radiator. Radiators can lose water in a variety of ways, and often need to be refilled. The other possibility is that the water is not being circulated properly. I should add that cars do heat up quite a bit in the sunlight on a hot day, which adds significantly to the chances of overheating the radiator.
There are several reason why a car might lose antifreeze. The water pump might be bad, one of the radiator hoses could be leaking, the radiator could have a leak, a freeze plug could be leaking, or it could have a blown head gasket.
This did not happen.
When your radiator fails in a car, your car will overheat. Sometimes it will explode with steam. Usually you lose your radiator coolant. Often you will have to replace your radiator.
It could be one of 4 things. 1. Bad radiator cap 2. Lose hose clamps at either the heater core, radiator, intake or water pump. 3. Bad water pump 4. Blown head gasket
Never flush a radiator. When flusing the radiator theres no way to be 100% sure that you got everything out, and flushing a radiator will only losen things up that can get into the engine, clogging it up causing you BIG problems... Its okay to drain and refill the radiator, but never flush one. All of those deposits that's getting lose, some will come out but what doesnt will find its way into your engine, causing you a huge headache.
you get dehydrated
No, leaves can lose water.
