Yes and no.
Yes: If you have a reverse flow engine which would be an LTI or L99 which were found in big Chevies, Buicks, Corvettes and Camaros, Then you need a reverse FLOW pump. It is driven by a shaft from the timing gear, so does not have a pulley on it at all. It does not match up with a non-LT-1 block.
No: If your water pump has a pulley it can be either standard rotation or REVERSE rotation. If it is driven by a V-belt it is standard rotation. If it is driven by the back side of a serpentine belt then it is REVERSE ROTATION. This pump will have a pulley that is smooth and wider than a V-belt. These pumps will physically bolt up to the same block but the REVERSE Rotation spins counter-clockwise as viewed from the front of the engine. My '93 Suburban has a Reverse Rotation pump because it has one serpentine belt running all the accessories. When I put a new Edelbrock pump on it I made sure to get a Reverse Rotation pump. Your auto parts store genius should be able to get the right pump for you if you know the make and model year.
Front of engine. Fairly easy to work on. Make sure it is replaced with reverse flow water pump.
Chevy installed a water restrictor in the heater hose fitting, It is designed to slow the water flow up a little so it won't make that noise. It has probley decayed away. It will not hurt anything. It just makes that noise.
Of course
For example, you can make an analogy with the flow of water in a tube.
a dam is made by a beaver which they make to stop the flow of water
sensation of warmth
by do an exersize dud <><><> Yeah, Exercises help, Try "Reverse" wanking your penis, it helps the blood to flow better. E.G, grab a Needle and prick your Finger, then "Reverse" wank your finger, more blood will comeout right? It helps the blood to flow. Just don't grab a needle and prick you penis 0.o that will hurt...
There is a difference, it will not work.
Reverse osmois and distillation will also give you pure water.
they conserve energy because it uses energy to make water flow into your taps.
the roots make the water flow up from the ground through the xylem.
I watched the ebb and flow of the ocean water.
