Q:My 1990 Ford f150 water pump is leaking from 1 spot underneath. It is brand new, What's going on?
if its leaking from the weep hole then u have a bad pump.....return it and get another.... if its leaking from a seal or from the silicone ....u will need to remove it and reinstall it......this time make sure silicone is evenly spread ......
Q:Submersible pump coupling, what does this coupling mean?
Submersible pump, mostly in sewage sewage pump, this is more common, QJ submersible pumps generally can not use coupling devices
Q:Replaced the Radiator on my accord last week, and this week the water pump failed. Are they related?
The only way they are related is that they both have coolant circulating through them...frankly it is unlikely the replaced radiator had anything to do with it, but if you found the leaking radiator when the steam started curling up from under your hood, then it is possible that gave the water pump that extra reason to fail...probable really.
Q:Which 12 volt dc water pump should I buy for my camper?
If you are connected to a campsite water supply you do not need a pump. The pump is only required to deliver water from the fresh water tank of your camper to the faucets and if equipped toilet of your camper when you are not connected to City water, ya I know I have probably been connected to an actual City water supply 4 days in over 10 years of trailer camping... but any campground water supply is referred to as a city supply in the trailer literature. The only accessory I recommend to have is a combination filter which will stop both sediment ( very common in campground water lines ) and secondary charcoal filter which will reduce both taste and chemical intrusions on your system / palate. Would I buy a basic system demand pump? Yes, but if the cost of the pump stands between your camping season and your camping plans for the season, cancel the pump and camp!
Q:what r the signs water pump is going out on 2000 ford focus zx3 2.0l zetec dohc? thanx in advance.?
Do your cooling fan(s) operate? One of the common problems with these cars, is for the cooling fan resistor to burn out, causing the low speed cooling fan not to work when commanded by the PCM to work. When this happens, the engine will overheat. Regarding the water pump itself, is relatively simple to access. However, the engine mount needs to be removed in order the gain clearance for the pump pulley to be removed, and then the pump itself. Check the green with black striped wire, and the green with red striped wire leading to the resistor first though. It is secured to the cooling fan shroud by a simple plastic lock clip. This part is far simpler to access than the pump. Hope this helps.
Q:Question on water pump?
I do not know the kind of pump you are referring to. I will give my personal expertise. If it is a pump taking water from a tank, the piping might be loose, the knocking may be corrected with some air ventilation pipe. If it is pumping from a water tank: I suggest you look at a submersible pump capable of supplying water to 3rd floor. This kind of pump is less noisy. The noise at start, is the electric starter, and the noise at the end is when water returns and seals the stop valve. Also some air may be in the pipe, you need to purge the pump, as often as needed, try this first, and then the others. Good luck
Q:how do you start a water pump?
Lonzo has it right
Q:where's the coolant water pump located on a 1999 Honda accord?
Most likely your water pump is bad and leaking out of the weep hole on the pump, a water pump has a hole in it so when it goes bad water will start to leak water out of it.,The water pump is going to be on one end of the engine behind the timing belt cover , you wont be able to see it without pulling the cover. On most of these small cars the timing belt runs around the water pump.
Q:Timing belt and water pump change?
There is no guarantee on how long the water pump will last, but normally 100,000 miles plus. But that is true of a timing belt too. The water pump has a weep hole at the bottom, visually check for corrosion or rust in that area. If you see some, could be a sign that it is ready to go soon. If not, then do the repairs that you can afford. But why the heck are you changing a timing belt at 60,000 miles.
Q:Is it the a hose or the water pump? ?
if its leaking somewhere you should be able to see where water is leaking from the motor, if its leaking from a hose, then replace that hose, if its leaking out of the water pump then its either the pump or the gasket, if its leaking out of a freeze plug you will need a tow so get the freeze plug replaced, if there arent any leaks then you will need it towed to either get new intake manifold gaskets or a new head gasket. price could range anywhere from under $20 for a hose or up to a couple thousand for a new head gasket.
