Tolerance of water pump play?
i think i already know the answer but is there any tolerable amount of play in the water pump bearing? Just noticed mine has some slight up and down play like if you were checking the wheel bearings. I can barley feel it, but can hear it. Not enough play to see though. Am i looking at replacing my water pump soon? :BangHead:
Are you saying the bearing is noisy while running?
Or are you saying you can hear the play in the bearing while pushing/pulling.
How many miles are on this pump?
Since the clutchfan is on there,how can you be sure it's the pump bearing you're feeling?
The Hi-flow pumps are a no-lose situation. IIRC they have a slightly bigger bearing in them, and mine has over 100,000 miles on it. But the big deal is that it has an anti-cavitation plate on the back of the impeller, making it possible for the pump to move more water at any given rpm. This allowed me to slow it down, in an effort to not throw a belt at 7000rpm. It seems to have worked!, cuz i still have a 10 year old belt on it,lol.
If you don't mess with the drive ratios, it's still a no-lose deal in two ways; 1) it will outlast the generic rebuilds maybe 4 times over, and 2) it can move more water, keeping your cammed up engine cooler.......if the rest of the system is up to the task. If no, then it's still a no-lose situation, cuz the thermostat sets the minimum water temp, so if, I say if, the pump moves more water than it needs to. the stat will just choke it down. There is no downside to a hi-flo. Mine was purchased new in about 2002, making it the cheapest pump I ever bought.
Just like my Optimus battery. It's been taking a licking in my trunk since about year 2000, and it's still ticking..
