Please Help!!!

Found in my garage today that I was leaking alot of coolant underneath my rig. I searched around and it looked like it was coming from my water pump. I had it checked, and it is confirmed. The guy wanted 410.00 for the pump, and I passed on it. I checked ebay, and found this BRAND NEW.

Can anyone tell me if this is exactly the pump I need?????? And, for this price, I can't pass it up....

Thank you all!!

ITS THE SAME AS A CHEVY 2500 HD PU 6.0 GAS. Nappa or Autozone has them cheap under $100.00. get a new one not a rebuilt . very little skill required to change one ,but you will have to work at it . it's a 2.5 hour job for me . the only hard part (if you have never done it B4 ) is getting the fan off the pump . this is a good time to flush and change the coolant and thermostat. use Dexcool with distilled water.

I didn't know the OEM was a Bosch...

Rock Auto has about 10 different brands including OEM Bosch for $108, starting at about $75, $80 for the AC/Delco...

Double check, 9 times out of ten its just the gaskets that leak. Replaced many gaskets and only a few pumps. If i was betting money on this one i would replace the gaskets and see what happens. Let me know and i will send ya the torque specs, a critical part with these type of gaskets.

Hey Guys would like some advice on using electric water pump full time since I run all electric fan setup. My concern is the electric pump would be in a no stop pumping situation until key is turned off and Mall Queen is on rest time.

I have 2 things that will be different in 2009 driving use as I plan to drive it more and enjoy it.

1) I will be pulling about a 25' to 30' travel trailer to shows and some camping to fish. I know from what little research I have done is that the newer model pumps can push an amazing number of gallons per hour which can actually be risky in that coolant could be pushed to fast through radiator not giving enough time for heat transfer from coolant to rad. fins etc.

2) I hope to go in March 2009 to Goliad, TX for try at land speed trials. It will be fairly cool but, still top notch cooling needed. Although runs are short and quick cooling should not be major problem here. The fact remains careful choice of electric cooling pump for wide range of needs is still important.
I do not want to underestimate the cooling in this situation but, surely not as tough as towing.

I would appreciate any knowledge in this area and very grateful to any who take it upon themselves to do research to help me in selecting the best dependable pump a well as best volume pump that can take care of many needs. I think some are adjustable to meet varying situational needs.

Thanks for any help,

TAZ

yes, could you send me torque specs? And, is that something I can get at Napa or Autozone?

although I'm no expert on this issue. I would never pull the water pump and change gaskets without changing the pump as well. Same amount of work, sure would not want to do it twice. (even if the gasket swap worked, how long before the pump goes out anyway. 60 to 80k)


Good luck

Your right if ya dont mind spending money when its not necessary, the pumps on the gen 4 motors have been standing up pretty well though. Torque specs are tighten all 6 bolts to 11 ft lbs and then do a second pass at 22 ft lbs.

I just changed my water pump about 3 weeks ago and purchased it from napa it was new and included all new gaskets. My pump was leaking around the nose of the pully and I have 90k on my truck. Its a good time to replace belts and hoses keep old ones for spares. cost was about $120 I think.

thanks for everyones help the other day. I ended up changing the water pump, thermostat, and serpentine belt. I should change the ac belt since I was in there.... but I'll do it this weekend. The bank1 and bank 2 issue was all resolved when I found my intake tube from my K&N was loose going into the manifold. Causing unwanted air. Which was great!! So, I didnt have to get any O2 sensors!! Coolant flush coming later on today and changing the a/c belt cause theres a bit of sqeeling going on.... hope that fixes it...
