- Q:I have a 1996 Volvo 960, wagon. I need to replace the steering and water pump on my wagon, and I am wondering if any how can give me instructions on how to do so...
- the water pump on this car is driven by the timing belt so follow timing belt replacement procedures for this, keeping in mind that you should also replace the belt,idler pulley,tension pulley,and gas-tensioner at the same time.once there the pump is held by 7 bolts and replacement is straightforward[gasket surfaces must be perfectly clean and as this is an interference fit [valve bender] engine the timing belt procedure must critically be adhered too. as for the power steering foamy fluid means one of two things, either you have a leak in the system [pump,hoses,rack. causing the pump to cavatate due to low fluid or someone added a fluid that doesn't belong, requiring a flush of the system [once again if fluid was added there is probabley a leak somewhere] if indeed the pump is found to be bad [very rare] after removing the serpintine belt tensioner the pump can be unbolted and removed. good luck
- Q:looking for the comparison and then finaly the conclusion about the water pumps instaaled in the IC engines. Where we should stick to the tradional mechanical driven water pumps or electrical water pumps? which one is better!! any information/ response is appreciated
- The belt driven pump is operating all the time the engine is running. This takes some of the HP of the engine and causes wear and tear of the belt and the pump. The electric driven water pump is operated on demand from the water thermostat and only runs when the water temp. rises above the setting and shuts off again on returning to the setting. Saves engine HP and pump wear and tear...It's much more efficient.
- Q:How do the water pump work please till me water pump mechanism?
- I assume you're asking about a car water pump. Inside of the pump casing is an impeller (a disc or wheel with vanes). The impeller is connected to a shaft that's connected to a pulley wheel driven by the drive belt from another pulley wheel mounted on the engine shaft. The pump, the radiator and the hoses make up a water filled, enclosed system. As the pump rotates when the engine is running, it circulates the water around the system removing heat from the engine and giving up the heat to the atmosphere through the radiator. ....
- Q:i got that special socket but everytime i try to loosen the pump going clockwise i can not get the pump to come loose the socket just slips off any suggestions these is a northstar engine
- You sure you have the right tool?? There are 2 different tools they came out with. Cant remember the year but Cadillac changed the water pump design which the tools had to change. Neither one will work on the other design. Both almost look the same except the teeth stick further out on the older design. I always use a impact, put the socket on your impact just bump the trigger enough to get the pump to turn a little. But not too much or you'll break the ears of the housing then you'll have to replace the crossover asy I did see you said CLOCKWISE!!!!!! Make sure you are turning it to the direction to tighten, this has the reverse on/off direction
- Q:Building installation problems, beginners, many problems need to be solved, thank you!
- 3, sewage pump flow per hour 40 square water head 15 meters, 1600 rpm, with power 4KW
- Q:my sump pump keeps filling with sewer water. i cant figure out why or where it could be coming from. and the smell is awful.
- A sump pump is designed for use in the basements of homes whose water tables make them prone to flooding. Many basements are actually below the water table. This means that should the integrity of the walls or floor of the basement be breached, the basement could flood. This would result in thousands of dollars of water damage to anything in the basement, as well as the loss of anything irreplaceable that's stored there. Even should no breach occur, a great deal of moisture and condensation forms over of time within such spaces. Typically the water drains into a hole in the basement floor called a sump pit. When the water level in the hole rises to a certain level, the sump pump engages and removes the water. A pedestal sump pump, for example, has a long rod that extends down into the sump pit. At the top of the rod sits an electrical motor. Beside the rod is an inflated plastic bubble such as the kind one finds in flush toilets, attached to a pressure switch. When the water level rises beyond the bubble, the bubble is buoyed upward and activates the pressure switch. The switch turns on the electric motor, which sucks the water out of the sump pit and passes it through a connecting PVC pipe. This pipe may lead outward into the soil away from the house's foundation, or it may be connected to the wastewater system that connects to the house's drains and toilets. In either case, the water is pumped out automatically.
- Q:My mechanic doesn't get back in town until next week, and I'm struggling without my car. I don't really have any other options mechanic wise and I'm not dropping $1000 like meineke wants.How easy is it to follow the Haynes repair manuals or any other repair manuals? I have a 1996 dodge avenger and I need to replace my water pump. I know it's a time consuming task, but is it especially hard to replace it?
- Try another repair shop. I had my water pump replaced for about $300 and that included the pump and labor and a belt ... Meineke is pricey. You can do better pricewise... Ask around... neighbors... people at work... My water pump was under something else that also had to be taken ou to get to it... not a job I'd want to tackle.
- Q:I live in a condo building -- 3 floors, 7 units. In our storage units (right below my unit) is a water pump that was hooked up with the intent of helping the water flow to the 3rd floor. Everytime the pump goes off, it rattles, then makes a loud noise when it kicks off. The developers created a drywall box that houses the pump, which is surrounded by isolation, but it doesn't seem like it helps the noise. The pump also rattles the pipes that connect directly to the pump.My question is -- is this rattling normal for a standard water pump? If so, is there anything I can do to help cut down on the noise? If this is rattling is not normal of the standard water pump, what would it cost to replace it with something decent?
- I've been around booster pumps that were extremely quiet -without any soundproofing at all.And the pipes don't rattle. You should find a plumber who knows what the hell he's doing and get that crap replaced.
- Q:what could cause a impeller on a water pump to be completly shredded up i just had to change mine in my toyota camry and was wondering if i could do anything to prevent this from happening again?
- It was prob just a cheap water part. make sure you get one with a cast iron impeller
- Q:What do water pumps do on a car?
- pumps water
