Would a bad water pump make a whinning sound when the engine is reved.....ive checked everything off as to why my car is running so hot and im down to the water pump.....ive put a New thermostat....no leaks anywhere.....no oil in coolant....no coolant in water.....no white smoke.....Fans do turn on.....new colant and i bleed the air out.....but the engine is still running really hot....my car calls for about 13 quarts of coolant but upon refil it took only about 4 quarts...... .. . uld this be signs of my water pump failing.....the pump is not leaking and when i took the housing off the water pump and turn the engine the blades did rotate...but at a higher rpm with the car together i heared weird noies kinda like a whinning sound from the water pump.....1995 Oldsmobile Aurora194,000Northstar 4.0 V8
It relies upon lots on the engine interior the vehicle, and understanding the 365 days could extremely help. $600 is outrageously costly for the two.2L engine and outrageously much less costly for the two.4L engine. you could replace your very own on the two.2, with a sprint help from somebody experienced. I certainly do no longer advise attempting water pump replace on the two.4L engine! No timing belt on the two. If the leak is sluggish adequate you could carry known antifreeze and purified water (no faucet water!) and fill up each morning and each afternoon. once you're including greater advantageous than a quart of the mixed beverages (the two premix or manually use a million/2 of each) you will could want again up with yet another plan. As thebax says, stop leak won't artwork on a water pump.
Your cooling system holds as many quarts as your manual says. The radiator, block, cylinder heads, heater core and all hoses are figured as 100% empty in your manual. You probably drained just the radiator instead of flushing with a Prestone or Peak flushing T spliced in the heater hose return line and draining the block. You're down to two more things. Clean the cooling system with two 33 oz. bottles of Prestone Super Radiator Cleaner and follow the instructions on the back of the bottle to a T. It's a lot of work to do it correctly and understand why you're doing what your doing as you work along. If the water-pump isn't leaking from the weep-hole underneath the output shaft there's not a darn thing wrong with the water-pump. Finally, haul out your wallet and buy a new radiator after uou've cleaned the system. With the best of care automotive radiators crap out after 14 years of use. The internal cross tubes build up with corosion, calcification and rust.
if you can wobble the pump shaft the pump is going bad but w/o leaking it really should leak first. get the engine to operating temp and from under the hood rev the motor at a steady speed to see if you have a hose sucking shut also check your rad pressure cap it just might not be releasing the pressure at the proper temp. good luck
the water pump some times whine when it goes out.the radiator could be plugged.when running sqeeze the top hose to make sure its ciculating.this will let you know if its the water pump is out or not.
NOTE... GM had a problem with the radiators filling with crap. If you can't put 13 qts. of coolant in it then you have a plugged radiator. Replacement is required.
