Three months ago I have finished my top end engine rebuild project on my 2000 Disco II, which I have written about https://landroverforums.com/m_19788/tm.htm

Everything went well with the repair work andthe car now has 4,000 miles on the clock since then (110.5 K total). Last week I have noticed slight coolantodor when engine was hot. After close inspection, I have discovered that the newly installedpump I have purchased from Brit. Pac. under with trademark ALL MAKES, has developed seepage right through the small vent hole on the pump shaft housing. The seepage is so slow, that the coolant actually evaporates before it has a chance to drip under the car. However, the problem is there, and it may get worse with time.
I have taken perfectly good pump off, for reasons that it has 106K miles on it, and since I am doing this project, may as well. Now I do want to replace the faulty new pump, however, could I put the old one back and trust it will last for some time, or considering the service it already provided, it would not last too long anyway. What is the typical life expectancy for the original water pump?And finally, can I trust any other aftermarket pump, or shall I just get one directly from the dealer.

Any input on the above subject would be greatly appreciated.

 

Its not common to get a bad part water pump or anything else, but it does happen.
I have had good luck with after market pumps and OEM also.

OEM pumps have lasted 50k or so for me, at 102k I put a after market pump on. (LR)

On another truck is was replacing the water pump every two years until I went to a after market.
The last five years of the sixteen years I had the truck the water pump was still good.

Do what gives you peace of mind.

 

Thanks Landzu. I am inclining to buy a new OEM pump.

 

 

Eleven years too late.
Also, punctuation and writing in English helps the rest of us understand what you're trying to say.

 

 

I agree. I went with the Airtex withn the brass impeller about 5 year ago. No issue so far.
