Thread: Anyone had their water pump fail ?

Old thread which was mine to begin with, but I am now revisiting because my Ody is almost up to 150K miles. To answer the last question: I never replaced the water pump at all....question of OEM vs aftermarket part does not apply. I am getting ready to go at the timing belt again (second time is always a snap compared to first) and this time, I will replace the water pump and tensioner at the same time, just for insurance.

CNN, I did a search of the internet and found that what I had stated was correct, the water pump bearing is lubricated from the coolant, no not exclusively but it does in fact receive lubricant from the cooling system. Yes the bearings are shielded but they are not "tight" from coolant penitration. As far as a water pump lasting from 40 to 160 K miles, again, not sure where this comes from, no expected MTBF that I have ever seen in...

Some thoughts.............. quote: [i]........... The bearing is lubracated via your coolant so it is important to keep fresh clean coolant in you cooling system. Your biggest danger would be if the bearing goes bad, but again as a general rule they dont go from functional to bad overnight. If the bearing does go bad then you would get some "play" in the bearing and this will also often result in seal damage and coolent loss (there...

What I would do in your case is to leave the WP in there for now but change the timing belt early at 160K or so (whatever the interval is for the timing belt under severe schedule). If anything seizes that causes your timing belt to go, with this interference engine you are looking into the thousands to repair it.

Re: Some thoughts.............. quote: Originally posted by cnn 1. WP, as a rule, lasts anywhere between 40K and 160k miles, depending on the car. 2. However, for the sake of safety and engine porotection, most mechanics replace the water pump at around 100K or so, again depending on car. 3. The WP bearing is lubricated by grease from factory, protected by the inner seal. So the antifreeze never lubricates the bearing. However, when the inner...

My 2001 Odyssey has 197k. The water pump started weeping a few months back (~10k miles). The first TB was replaced at 105k and the WP free play was check only (no problems found). Since I do my own maintenance, labor is free and I wouldn't mind having to go back in if the WP failed between timing belt replacement. I have a new WP and TB (all OEM parts) ready for installation. Just waiting for an open time slot in my schedule to do the...

And the water pump was not replaced at 105 with the timing belt because?

Well, I had timing belt and water pump replaced at 115K this past August 06, no big deal. January 07 the water pumps starts leaking from the weep hole on water pump, okay take back to garage to fix. Replaced water pump but some how they screw up the power steering. Did not bleed system properly, they say. A couple weeks ago water pumps starts leaking again now I hear noises (bearing) I guess from water pump. Not going back to the that garage...
