Q:I think my water pump is going bad but figure id ask everyone to see what they thought. I leak coolant like the first 20 min i drive my truck and then it will seal itself up for the next day or two then start leaking again. It is getting leaked all over the belt and the fan is spraying it all around so you cant tell where exactly its coming from but i checked all the hoses and they are good and im pretty sure its not the radiator. Also, when it is leaking there is a loud whining noise when my trucks on and i heard that can be from the pump too.

LOOK okorder on internet! WHAT SIZE IS ENGEIN HERE! FOur, five, six, eight yidner from WHAT COMPANY! NOBODY can answer thsi question for you without MORE DETAILS! THANX!

Q:i took off the lower unit to fix the gears. im not sure ill be able to put it back on with out knowing how things work in there.so how exactly does the water get pumped. and what does it have to do with the gears, because even though the prop wasn't turning, the water was still pumping.thanks.

did you put the dot of adhesive on the Keyway to hold it from slipping out of place ? Are the pump plates worn around the impeller ? If you just replaced the Impeller and NOT the whole housing, and plates, that is NO GOOD, you must replace the whole unit.

Q:I am looking for a small water pump that I can turn on and off using a computer, preferably via USB. If someone could please post a link or a method of me doing this myself, I will be very appreciative.

I'd look for a USB IO module, add a relay, and switch a standard pump.

Q:ok im ready to install my new water pump but it has to gasket in the package i no where one goes it shapes to the water pump but i dont no if the other one is used, and also where does the o ring go in the big hole in the center does it have to be pushed down into a seem or something and do the to out side holes need o rings as well, and does the hermonic balancer seal need to b replaced

The water pump should come off the block with 4 bolts, the gasket goes between the body and rear plate. The o- ring fits onto the transfer tube that travels between the valley of the block. Add a little lube to it to make installing the pump and cover easier. The lower t belt gear should slide off easily, if not a bit of heat may help, careful not to break the oil pump (front end of block). The upper cam gears are best loosened slightly while the belt is still installed. If not try slipping the old belt over the gear and holding the outside of the gear/ the belt. Air tools may be required due to torque required.

Q:I have a 2004 Toyota Sienna and it has 80k+ miles on it. I guess it is the drive belt that is making the noise and I decide to have it changed. I can have the timing belt changed too because it is due at 90k miles. The dealer guy told me that I should also have the water pump changed too because of 2 reasons:1. the new timing belt will cause pressure to the old water pump. If not changed, it will leak in weeks.2. it is cheaper to do it altogether.Without changing the water pump, it would cost about $300.All would cost $1000+.My friend who also has a Sienna that has more miles on it, told me that he did not have to change the water pump.Your advice about the water pump is?

Change the the timing belt if it breaks you can bend a valve the smaller import engine have what they call a zero (0) tolerance.For the water pump it runs off of the timing belt so since your timing belt is already off you should change the water pump.Another words you will need to tear the timing belt back out in order to change the water pump not if but when it goes out.The dealer price is not bad for a dealer you might be able to save a little more if you shop around GOOD LUCK

Q:i heard a water pump should not be able to move.is that correct? It is a 1995 RM250. there is no clogging in the pipes coming from the radiators with 2 fingers require force to move them but with the 1 finger it requires no force to move a couple Centimeters.

The water pump is turned by the primary gear on the crankshaft. When you were turning the water pump - the crankshaft was moving the piston up down in the cylinder. The couple of centimeters of movement is just the play between the gears - that's normal.

Q:me and my friends are contemplating going on a road trip.almost 20 hours of driving.but we dont have a water pump, can you drive without one?

You can't go more than a few blocks without the car overheating if your pump is not working. Working or not, I guarantee the car has one. Unless, of course, you are being silly, and really own a car with an air-cooled engine!

Q:I took out the thermostat, filled coolant level to upmost, my car still overheats, it doesnt leak ne where.How can I tell if the water pump is workin?

if you can look down inside the radiator watch the water see how it moves.... check you hoses if any of them are soft or fat looking.... and it dont have to leak to be bad but in most cases it leaks..... most of the time when a car over heats its a flow thing

Q:coolant leaking from weep hole on water pump need to know what i need to remove to replace or should i call mechanic

Take an autoshop class.

Q:The coolant in my '92 Le Baron is leaking, so I may have to change or replace my water pump.., any ideas?

You take it out and replace with new. In the process you might have to remove radiator, drive belt, several pulleys to get to the pump.
