Squealing Water Pump
My water pump is letting out an ear piercing squeal at start up and whenever I give it any throttle until the car is at normal operating temp of 180 degrees. This after the coolant had been drained for about a month While I was cleaning and painting the engine with the Alternator, PS pump and AC compressor pulled off
I have three belts - Alt, PS and AC. The Alt and PS belts go around the pump pulley but the AC does not. I ran it yesterday trying to eliminate if and what belt was causing this. Ran with the Alt belt off - Squeals. Took off the AC belt - Squeals. took off the PS belt and put the Alt belt on - Squeals. Had all three belts off - no squeal. So, only when the pump is being turned does it squeal. Fan has no obstructions. Zero leakage from the water pump which is a cast iron one.
I ordered some Bar's water pump lube and anti-rust additive. No one seems to carry it in stores. So, I will add it on Thursday when I get it and see what happens.
Has anyone used this product? If so, was it preventative or trying to solve a squeal problem? If done to try and get rid of squealing did it work?
I am going to order a new pump and if it continues, will bite the bullet and tear things apart again and replace. If the current pump stops squealing, I will have a spare pump. But, I might just go ahead and install it this coming winter "just because."
Any observations or advice is welcome!
