Question:

How do i know if my water pump went out in my car?

I have a 1998 ford taurus. It started to over heat so i turned on the heater full blast and it didn't get hot. so i put antifreeze in it and i turned it on and it seemed ok but it started to over heat again and the tank for the antifreeze looked like the cap was going to pop off. I was just down the road from my house so i thought if i drove slow i could make it home and it turned on ok but when i put it in drive it stalled. Does this mean its the water pump??????

Answer:

If your water pump goes bad it leaks. A Lot. You can watch the water pour out from under your car like an open faucet, car running or off. If you are having cooling issues and must get home or to the shop slowing down will only make it worse. Your radiator is designed to use moving airflow to cool the water system. Even if you have little water in your radiator the air will help cool everything under the hood... to an extent. Between 50 and 60 are the best speeds for cars low on water. Trust me. If you're not seeing any leaking water then it could be one of these reasons: Radiator clogged. Thermostat bad. Head gasket.
Hmm it has somthing to do with all your fluids if antifreeze cap looks like that but it would be best to get it looked at I may be wrong
sounds like Low water level and a possible head gasket failure from over heating!( low water levels do this) you may? be very lucky and simply have a stuck thermostat or faulty filler cap. ( keeps system pressures correct ) try replacing filler cap as very cheap, also before doing so run engine with full water cooling system with cap off for a minute or two and have somebody rev the engine a few times. we should!! see some water flow across the filler section under filler cap. this will be sign the water pump is working. no flow is possible pump failure. in order of likely hood will be 1) head gasket failure 2) water pump failure 3) filler cap failure.
This is bad news. For some reason, you ran low on antifreeze. It may have been your water pump or a hose leaking that caused it. Here's the problem now. More than likely a head gasket is leaking, or a head is cracked. Either way this is a big job and should be diagnosed properly first. Sorry. Good Luck!
Its over heating because either your thermostat is messed up, bad water pump, head gasket, bad radiator.... but sense it was empty on fluid you could have a possible leak in the hoses or a head gasket or your water pump is leaking engine coolant. for head gasket check if theirs water in your oil ( take off the engine oil cap and see if theirs a white foam on it) if their is then your head gasket is screwed, to check if your water pump is working start the car after it has been sitting for a long time so its cold, touch the black hose thats ontop going into the radiator ( usually the biggest one you can see) and squeeze it while the car is running, if you feel water moving then your water pump is ok, you might have to wait a while for the car to get hot a little to check....cant think of anything else right now as im sleepy.
