Looking to replace/fix the heater water pump (2000 xj8 base).
Part # mnc6710ac (?)

Can anyone confirm if this is also Bosch 039202002, or what the Bosch (or any) equivalent would be?

Thanks, Lowell

 

Are you sure the pump is broken? Just asking as while a common problem on these cars, clogged heather core is another. I also thought my aux pump was dead and bought another one. To find out the one I had worked just fine and just needed to flush/backflush the heater core. Which is what I need to do every winter (it's just about that time again....). Cheers

 

Here's the piping - make sure you backflush it or you could really jam the matrix up!

 

What coolant are you guys using?

I don't understand all the cooling system problems ... I can see how it may have happened in the earliest cars that switched coolant .. but by 2001 they were all using the newest products?

It's so important to stick with the correct fluid -- and keep the system filled.

I believe the pump is made by Denso -- that's not to say that others are not selling a rebadged version.

 

Thanks. Upon further review, I'm going to leave well enuf alone.

Had suspicions about the aux pump for a while. Did a clean/flush/new (then a tstat, then water pump, and 1 new bleed tube), and it seems to be working ok. Not true winter yet, so we'll see then.

Now, about the door handle....


Thanks,

Lowell
