Q: I have a 1999 Mercury Grand Marquis vehicle. How do you know when the water pump is going. Is their any particular noise I should be hearing.: There is no noise associated with a water pump going out that I am aware of other than the engine exploding due to excessive heat. The dash guages; especially the engine temp guage, will give you a clue as to a cooling problem, whcih is what the water pump is for. The water pump prevents the engine block from overheating. When the pump fails, the engine overheats and will either shut down, or the engine will burn out. The best way to tell is to monitor the temp guage. If the engine is running hot, it either the water pump, lack of water in the cooling system, or Thermostat failure. Best to have a mechanic check it out. Cheers!

Q: I suddenly have this rattle noise whenever the engine is running but it diminishes with speed. It almost sounds like spark knock but spark knock would get worse at speed. It could be the water pump. Would a water pump get louder with speed, or go away as this does? I feel a tiny bit of in-out motion in the shaft but not side to side. Car is a Geo Metro and does have hydraulic lifters.: Its possible go find yourself a four foot piece of hose and put it right on top of the water pump with the car running and stick your ear to the other end. you will hear the bearing if its going bad, it could also be the alternator, but, if you have a Serpentine belt odds are its the belt tension er and this thing goes bad often. If it has a belt tension er, may as well replace the belt too. good luck

Q: it's not doing anything. about a month ago, i changed the pressure switch because it the water just suddenly stopped (like now), and after changing it, it worked again. I did noticed that after changing the pressure switch, it was tripping a lot (the pressure switch). when the water pump stopped again (this time), i went a bought another pressure switch thinking that it was the same problem, but this time it didn't solve the problem. Came to find out later, that the pressure switch that i had changed about a month ago, it was wired incorrectly - maybe that's why it was tripping a lot? so i did wired this one correctly, but still didn't work. Did i burned the pump? another note here is that it has been less than a year that i changed the water pump. My question is, what could the problem be this time? did i burned the pump because i wired the pressure switch incorrectly? any suggestion, please email me thanks!: what the hell are you working on?? Need just a little more input

Q: I have a Honda 20003 bf15 d short shaft Ineed to change the water pump I have removed the 5 bolts that hold the lower unit it on but the shifter is steal hooked up how doI unhook that?: Please get the workshop manual. From an imperfect memory it should be in forward gear to expose a link - but I could be confusing it with other brands. This brand has a known issue with the water pump if ever run dry as both the impellor and the housing can be damaged instantly. The pump should always be replaced as a full assembly, housing, seals and impellor, as detritus can easily block water galleries and that requires extensive work to remediate. The thermostat should be checked and replaced at the same time. Worn and damaged impellor material can easily end up through the block, head, thermostat etc. and that must be checked for as well. The lower cylinder can be down on compression caused by local overheating due to this and mud, sand and corrosion reducing water flow. An engine that very much must be flushed and looked after after all use - that includes all the larger models with this brand. They are quite a good engine, but seem very heavy for the output to me - particularly compared to lifting a two stroke on and off....

Q: honda acord water pump 1988: hello Purchase a how to book, because part of the water pump sits behind the timing belt cover.Hope this was some help.

Q: need step by step on how to change water pump: The water pump is ran by a belt on the back of the cylinder head There is a belt tensioner that is released by a 3 /8 ratchet . Once you get the belt off take off the pulley and next you will have to have a special tool that inserts into the water pump socket and turn it counter clockwise to release the pump .When you put it back together make sure you put a little grease on the O-ring so you don't damage it . They are fairly simple if you have the tool they should have one at any good parts store . Good luck .

Q: What do water pumps do on a car?: The water-pump circulates the hot coolant from the engine to the radiator where it is cooled and back to the water-pump through the hot engine again. If you had listed a particular car or truck as an example, some water-pumps push the hottest water in to the radiator through the lower radiator hose where it is cooled and then circulated back through the upper radiator hose to the cylinder-heads first then the block. This is the latest and greatest coolant circulation method because the cylinder-heads are the hottest part of a water-cooled internal combustion engine. The block temperature is always substantially cooler than the cylinder-heads. This is called a reverse cooled cooling system. One of these days to avoid confusion the makers of water-pumps should re-name them simply coolant pumps Race car engines are the only place real pure water is circulated through the cooling systems because antifreeze cuts cooling efficiency.

Q: i was wondering how hard it would be to chancge a water pump in a 1997 chrysler sebring.: Whoever quoted you $800 is a crook. I cant remember exactly how much I paid parts labor for my last water pump but Im guessing under $150. The car CAN be driven as is.Just be sure to add water regularly and do not drive it hot.

Q: The pump works and water goes to the house from the reserve tanks but there can be long delays before it cuts in after mains pressure is lost. After it stops the pressure gauge falls back slowly to zero. Pressure vessel is a sphere has a valve on top. Any suggestions ?: Espa Water Pumps

Q: Engine problem 1999 Nissan Sentra 4 cyl Front Wheel Drive Automatic 165000 miles ---------------------------------------------------------------- I have a leaking water pump that has to be replaced. I am calling around getting prices and some people tell me that I have to do the timing chain at the same time and that will be a great deal more money. Can I just replace the water pump? It seems that the water pump only will be about 200.00 but both could be 500.00. Please help: I don't know about a 1999 Sentra specifically, but when I replaced my water pump in my 96 Saturn SC2 I didn't have to do anything timing belt. Unless the mechanic says it just needs to be replaced the two items should not be related.
