I have 2002 xk8 convertible purchased in Feb of 2017.

To date this car has had four water pumps on this year.

Dealer decided to change before car shipped.
Thats two

Leak developed, my local shop indicated number two was leaking and needed replaced.


Now I have a leak again, goes in next week.

What does the water pump attached to, could this be the problem?
What are the chances of this happening?

 

I had something similar happen to me but it was only 2 pumps in about a 2 month span. There seems to be a variation in different aftermarket pumps and what type of material actually mates to the engine block. Some have a plastic surface, another metal. The metal one has worked well so far. Proper torquing is also important. I would not continue installing the same type of pump, it's a fairly straight-forward DIY to save $.

 

The shop had a quick look and indicated it is not the pump this time
Getting tried of this

 

Relax. It's a fifteen year old car and things are bound to go wrong. Have the cooling system pressure tested and then have the leak repaired. Problem solved.

 

I think hose leaks accounted for 80% of my total "restoration" cost. They all deteriorate and leak. Fix one, 2 more pop up.

Best of luck, we have all been there!

My "LOW COOLENT" warning light comes on every 5 or 6 days of driving without fail. I just top her up with about 300 ml/cc of water and the cycle continues...

Mine's a 20 year old, and the coolent loss can come from too many different places... Just make sure the water temperature does not rise enough to light the red warning light... Slow leaks are too troublesome to track down precisely, period.

i guess my concern is what would require the replacement of three pumps this year

 

Improper installation and/or poor gasket seal would be my guess....

 

Get yourself a fibre optic camera for you cell phone. I have found leaks, bolts I dropped and places you could never see into it with that $20.00 gadget.

 

I have one as well. Originally purchased to help with my rifle restoration projects, but it is also very useful when working on the car.
