The most likely failure in my 2001 Box base...

[BYprodriver]

So you gotta ask your self, "Do I feel lucky"! :chicken:

I've seen these water pumps go from "perfect" to failed in about 3 month's time. Preventive WP changes are never wasted money, they are better than a reactionary issue that STARTS at 10K to repair, IF you can find anyone who is willing to sort through the nightmare without just saying "you need a new engine".

I have 8 cars here with cracked heads now and resultant intermix, with one more arriving today. Those people would have paid good money to know about the issue that bit them silently.

The main reason for pump failure is people never flush their coolant and the Ph levels kill the impeller blades.

Which one do you recommend?
I see different pumps on Ebay or Pelican.

^ there you go. game set, match.


Now I don't feel so bad for having done a flush figuring 10 years was way too long for that to be sitting pretty, and despite reading somewhere that these flushes were unecessary in the 986/996.
I got another 20-25K miles out of the pump after that flush and the blades were intact when the unit itself finally let go at 85K miles.

People just want to stick a key in, and drive... They want to fix any issue with a keyboard.

Good luck with that.

So these water pumps don't leak or squeak or show any signs of imminent failure?
Its just BANG and it roaches your motor in an instant?

What does Jake Raby stand to gain by exaggerating?

Jake is better off if we don't replace our water pumps, the engine damage from a water pump failure is a major rebuild. His business is better off if he doesn't tell us about water pump failure damage.

Thats right...

And on top of that we don't sell ANY parts, so its not like I am trying to sell someone something they don't need.

I am done helping, fellas. Pulling the rest of the pre failure directives off the site this weekend and I'll just sit back and wait for the phone to ring.

You can lead a human to knowledge, but you can't make them think.

I just asked a legit question...I never said he was exaggerating
Im not new to cas, not new to sports cars. Every car Ive owned the water pump gives SOME indication of impending doom.
People on this board have described their water pump as leaking, making noise, etc., so I am just trying to clarify. Im not sure why P cars design a water pump that without any indication just blows out and grenades the engine along with it.
Does the engine ALWAYS get grenaded, or only if the vanes break and clog water passages?
