Q:Is it normal for my sump pump hole to be empty. No water in there.. ??: the pump does not go on until it is submerged with water, therefore if its not working now, you do not have a lot of water in your basement and you're lucky...thats what you want.

Q:It DID start after the Water Pump was put on. And i have not yet been able to detect a vacuum leak. The quot;whistling noiseseems consistent with RPMs, and the quot;dieseling(run-on) stopped in all but a rapid succession of 5 quick ~1-minute start/stops when the engine was fully warmed.. then it minorly ran-on.Could i be driving myself nuts over a Water Pump sound, and if it IS a Water Pump bearing, do i need a new Water Pump?1984 Chevy Camaro. 2.8 V6 carb'd 165,000 miles Auto.: one tell tale sign of a bad water pump bearing can be a sound like a jet engine, but there are other possibilities too, I take a 4 foot length of garden hose put one end on top of what ever bearing you want to check and stick the other end too your ear.a slight hum is a good bearing, noisy bearings are easy to diagnose this way. Just be careful, no loose clothing or long hair near spinning fan and belts, engine has to be running to hear bearing noises. As to the dieseling noises, this is your engine running backwards. this is extremely hard on an engine. Leave the car in gear then turn it off. if its a stick, put it in a high gear let the clutch out until motor stalls. However dieseling is usually related to timing and poor quality fuel. Change to chevron super unleaded, it has techron which will help clean out a dirty fuel system, your vehicle may have a out of time problem, and or tune up issues can cause this. get this fixed, the fuel milege will be a bit better, and your engine will not self destruct. If the noise is in the water pump then replace it. Sometimes a jet engine sound can also be present in the torque converter in a transmission (automatic only)

Q:its a honda accord 1991 Lx my car started overheating only when i stop when i go it doesnt overheat what should i check like the water pump: You can start with the engine cold. Take off radiator cap and make sure coolant is full. Start engine and wait while it warms up, keeping your eye on the temperature gauge. When it gets to operating temperature, the thermostat should open and the coolant should start rushing past the opening. If it does, the thermostat and water pump is fine. I suggest you make sure your radiator fan(s) is/are turning on at the correct time. Lastly, if you can't figure it out, get a new radiator cap.

Q:2005 pontiac grand prix 3.8 v6There is a scratching type of noise when i start the car. Looked under the hood and it seemed to be coming from the serpentine belt.Took the belt off and and checked the pulleys for any play and turned out the water pump pulley wobbles back and forth too much. Replaced the belt with a new one and want to replace the pulley. It does not seem to have a loose screw so i'm wondering if i can take the pulley itself off and replace it, or would i have to replace the pump too? Still makes the noise with new belt and you can see the pulley wobble a bit when the car is running.: You need to replace the pump itself. The wobble you feel is the bearings in the water pump that are bad. Good luck and hope this helps.

Q:Plumber quotes installing system using cross-over valve which some way ties the recirculation through the cold water pipes. This sounds like a short-cut. Are there any disadvantages to this system?: what your plumber is installing is a pump and temperature sensor under a sink , hopefully the furtherest from the water heater. what it does is sense when the hot water temp drops below a certain point, at which time it pumps the water into the cold line until the temp rises again.. the obvious advantage being , not having to wait a long time at the faucet for the water to get hot.. the also obvious disadvantage being electric consumption.. not only for the pump and controller , but also with the water heater clicking on a little more often.. not a lot of expense but a balance against convenience..

Yes if the pump is leaking but how did they come up with a leaking water pump after scanning the computer for the check engine light ?? Something dosen't sound right here and you need to have someone else look at your vehicle !!!

Q:can stress from to much weight cause the engine to get hot and cause your water pump to leak out the weep hole? and what else causes it to leak?: This could be normal wear-and tear. Poor cooling system maintenance will cause a water pump to fail premtutrely.

Q:Does the pump accessories have a shelf life?: No, they don't have a shelf life before and after the sale,Before selling, it is infinitely long, and there is no expiration date after the sale

Q:How do I tell the difference between a long and a short water pump? I have a Chevy 350 V8, a crate motor the same size is going in very soon. How do I tell which one I have so that I can get the correct brackets, accessories, etc.?: till it truly is made formerly 1970 it incredibly is an prolonged pump. bypass to a various factors place. the fast pump suits tight against the timing cover. The long pump has approximately 3/4 inch between the bck of the pump and the timing cover.
