I have a 2002 regular cooper and just started leaking from the radiator. Since I'm removing the radiator, I think it would be a VERY good idea to change the water pump, thermostat and the hoses, taking in consideration that this is a 14 year-old car and has almost 130,000 miles, I know is past due already.

I don't want to disassemble the front of the car again. I found the "water pipe" that goes from the pump to somewhere (I don't know yet), but I couldn't find any aftermarket replacement. The part number is 11537629401 and is the part #1 in the image.

I did search online and I can only find BMW/MINI genuine starting at $182...expensive! My car's trading value is about $1600, so I want to keep the cost as low as possible.

Open to suggestions. Thanx

 

I understand your reasoning for updating the rubber hoses on your MINI, as they can degrade over time, but is there a specific reason why you need to change the steel coolant bypass pipe?

Has it failed?

Is there evidence that it's rusting out?

If the coolant has been properly managed and changed at appropriate intervals, the pipe should be in good shape. If that's the case, change the hoses, but save your money and continue to use the bypass pipe.

 

Hi camucho!

Check our website and our Value Line that may have the right hose for you.

Ah! you're correct AoxoMoxoA, I didn't know this was a metal part....not even with the big clue of the "water PIPE" name. I just checked my car, clean the dirt and I can see is metal. I thought it was hard plastic. You just saved me $182 + shipping. Thank you.

 

 

Note....always look at your car before ordering parts!!
Good to hear you figured it out before ordering it.....
Just a reminder....
Change your coolant....it is the most overlooked item on the gen1 cars.
The car has cast iron block...and the first warning sign is you heater suddenly seems weak as the rust chunks block coolant flow in the heater core....

 

Thank you for the suggestion ZippyNH, I did check the car, but the pipe is so dirty, that I couldn't see it is metal. I plan on using new coolant. I changed it almost 2 years ago and I think is about time to change it again.

 

While you're in there and have things apart, you should change out all the oil-related seals and gaskets you can get to. A possible reason that your bypass pipe was dirty beyond recognition may be that your crankshaft sensor o-ring has been seeping oil for a while, and the dirt that's on the pipe (and front of the engine) might be from oil blow-off from that leaking seal.

 

Yes, I'm changing that seal, I do have some oil at the front of the engine. Any other seals that I could change? I knew about the crankshaft sensor, but I don't know about any other, so if you have any suggestions, send them this way. Thanks

 

There's also a camshaft sensor o-ring (on the passenger-side of the head, behind the engine support bracket) that can leak.

How does your valve cover and/or oil pan look? Are there signs of seepage? Is the bottom of the oil pan wet? If so, there's oil working its way down from above.

A larger job that may or may not be needed is the crankshaft seal which requires you to remove the crankshaft pulley in order to access/replace. Again, if there is seepage here, it will work its way down to the oil pan.

 

Hi I’ve have the same problem got the replacement part but can’t get the old part out unless I take the manifold out does anybody knows how to do it without taking the manifold out please advise
