Question Rb25det And Rb25det Neo Waterpump

[boostn0199]

I just bought a timing belt kit for my r33 and he sent me the water pump for the r34 neo which part number is 21010-AA527 but the actual one for the r33 are 21010-21U26.

I have sent a message asking him why he sent this one and he repled

"Hi there,

They are interchangable to all RB25DET, MOST RB25 guys prefer that one because there had been a few issues where people had coolant leaking around the slotted hole on the 21U26 pump, that one does not have a slotted hole so the sealing surfaces are much more substantial."

Is this true or not?

not sure bout the neos but my 25 pump leaked around the slotted hole, was a PITA

Ha, I am looking into a new water pump, as I have my major service coming up. Looks like I might have stumbled across a good topic. What timing belt kit did you buy? I was looking at the Gates one that CRD advertise on here for $295...

Edit: I just found this link after my post. Looks like it will fit RB25DET....

Quote: "Side note: For those of you that install the RB pumps with the slotted holes, you must be very careful applying the silicone sealant around the slotted hole. If not enough is applied it will start to leak around that area as the surface area for sealing is very small. Pay particular attention to that slotted area when installing!"

Found this post too.

It comes with the belt all the seals, thermo stat, tension and idler and waterpump all parts geniune. Is the kit crd offers without the water pump?

Sigh, none left. I have left the seller a message. Hopefully, he just hasn't gotten round to listing another one. I had a looked for others in USA, seems they don't have complete kits. Selling seals, timing belts, etc. separately.

[parkie]

Got one, its on the way. Best time to buy from USA due to the dollar for dollar exchange rate.

[boostn0199]

Yeah its a great deal with the dollar atm.
