Hi there,

Judging from the video below, does it means that the water pump need to be changed?

I was in process of replacing the radiator, which I bough with your help, and found that the cooling fan is moving...

Thank you for your help!

 

Oh yeah your water pump bushing is shot.
(only viewed the picassa clip)

Amazing how good the seals are on these things, isn't it?

 

If you've already got the radiator out, it will be even easier than usual to replace the pump. I did it on mine with the radiator in, and it was no problem at all.

 

Great, thank you guys!

 

one more thing, should i look to particular brand? or they all the same?

 

I can only speak from my own experience, but I used an off-the-shelf replacement from NAPA. It's served me well for the last two years, as have almost all parts I've ever bought from them.

 

Matthew,
Does this engine have any WP bolts that go into the jacket?
Do they need sealant to keep from corroding in place?

 

As in, are the bolts exposed to coolant inside the engine? I don't believe so, although I don't recall looking for that specifically. The replacement instructions didn't mention anything about that...the bolts I removed didn't appear to be treated in any special way, and I didn't treat them when I put them back in.

In short:

 

from what i can see, the lower bolt is exposed to the coolant.

 

Put sealant on the threads.

 

I did mine with napas shelf option, the cast iron pump they had for like $28. Worked out just fine. Didnt put sealant on any of the bolts, personally. If your gonna have the water pump out as well, consider changing the thermostat. I didnt and managed to get it out with the new pump on, after I had a problem with overheating, but it would have been alot easier with the pump off. Typically you change the thermostat when you change the pump.

 

Thank you for the hands-up! I changed my thermostat last year as a first suspect

 

I bought refurbished pump from O'Reilly and paid $16 for it. Looks like original, but much cleaner.

 

good idea, it was why I was overheating for sure. didn't account for the gallons of antifreeze that pump and lower hose were spitting out though, in my case.

 

$16? that's pretty solid.
