Water pump noise - Ranger Ford Cars & Trucks

a noisy water pump ( low growl or rumble noise) is a problem bearing and the cheapest fix is a new water pump
squeaks or other high pitched noises can be tested with soapy water on the belt--noise will stop for a short period of time
If the water pump housing is cast iron, you may be able to get a repair kit for the pump but the cost of the kit and the labor to do the job is generally around the price of a new pump

Bearings on a water pump failing on any car is a common problem! The water leaking from around the water pump area is the tell tale sign.........get it checked out and replaced as soon as possible to avoid further damage to the engine.

belts squeak or squeal if loose or worn . water pump bearings will give a low grumble like marbles in a drum. you cannot adjust a water pump only the belts to it. if the noise is a grumble then the fix is a new water pump unit.

If you had no noise prior to replacing the water pump then the noise will be at the water pump. Remove the belt and turn the water pump by hand and you should feel the noise. I suspect fan bolts too long or water pump bolts not fitted in the proper holes and hitting on the pulley. If the problem can be felt in the shaft of the water pump I would take it back to whoever fitted it and have them re do the job as it may be that the impellor is hitting on the inside of the engine housing water jacket.

A water pump is a device used to move liquids. A pump displaces a volume by physical or mechanical action. Water Pumps displace fluid, causing a flow. Adding resistance to flow causes pressure. A sump pump is a water pump example. ---------------------------------------------------------------------------

• Hi, I can help.
• When your water pump goes bad it will begin to grind. I had one I let got far to long and it sounded deafening when I opened the hood. You can open your hood and listen and see for yourself. The water pump is on the belt line, left side under the hood, last pulley toward the rear.
• Now if your asking can an oil change effect the water pump? No, not at all. Water pumps go sporadically.
• It would be odd that you heard no noises before the oil change and now the water pump is loud enough to take notice after the oil change. The bearings usually go a little slower than that.

• I would be interested in some more of the details to this. And what your overall concerns are. I'd be happy to further. help. Otherwise get a second opinion on your cars condition.

• Hope this helps and thank you for using FixYa.

A water pump on any auto making noise is a sign of bearing failure on the water pump drive stem. The only remedy is to have the water pump replaced or replace it yourself. The bearing gets water intrusion or dries out and the bearing fails. The water pump is not expensive but labor costs can be substantial depending upon the location of the water pump. Many water pumps are driven by the timing belt on smaller cars. Gaining access to the water pump often involves removing the timing belt cover and the timing belt. Failure to reinstall the timing belt in the exact same position as it was removed can cause catastrophic engine failure. Without your vehicle make and model this response is generic most vehicles.

if the noise is only with the compressor on it may need a new compressor. as for the water pump that should be changed when you replace the timing belt. that is usually done every 105k or 10 years. i would definitely check to see if that has been replaced because if it breaks you will have to replace the cylinder head

Maybe it's not the water pump that is making the knocking noise.

Water pumps generally don't make knocking noises.

It could have a spun camshaft or main bearing if you hear a loud metal to metal knocking noise.

The coolant pressure cap hose that connnects to the radiator:
Is this an overflow hose that leads to an overflow tank? If so, the hose may have a restriction in it.

grab water pump with both hands and see if it wiggles if it does its bad.bearing is worn.
