V6 water pump discovery!

[blue2]

Just a quick question, Ive just ordered my new water pump, just need to know if its a straight forward diy job. If not does anyone know how much it costs to have fitted, roughly? Thanks guys!

Hi dan, it is typically a 2-3 hour job that involves removing the timing belt and drivers mount, perfectly doable in situ though but can be a little tricky if you have never worked on a camry v6 before.

Thanks Paul, not something I want to attmept then, glad its not too tricky though.

I've just purchased a water pump from E-Bay from an outfit called IezuraParts, turns out to be one of the 'good' designs. Bit of a bargain at £21 inc. delivery :)

Great news, Jon. Let's just hope it works out ok for you :thumbsup:

I've just picked up a GMB water pump for my 1MZ.
Has anyone experience any of the aforementioned cooling problems with this design?

We haven't had any pump problems with the 1mz but i think that is because they all look like the Toyota design, that's the first 1mz pump i've seen with the cast impellor that was giving us problems on the 3vz..... i can pretty much guarantee you will see heatsoak issues at idle using that pump. It needs to look like the pump on the left in the original pic.

Hmm.. I'm quite sure the original toyota water pump I have here for a 1MZ has a similar impellor design as the one shown by knightrous. Since I'm moving house I'm not exactly sure where I left it, but I'll try to take a picture today.

-edit- I just remembered having a picture of it on photobucket, so here it is:



I can not comment on whether or not this is a good design, but it is at least toyota's design.

good work paul this is why twobrutal is a top website all the info is priceless

+1:thumbsup:

Excellent find Paul, it's the sort of thing that can only be discovered when you're constantly working with same components and something catches an experienced eye. You must have had a Eureka moment when you picked it up.

EDIT:I've only just spotted this thread but good work just the same

I mentioned earlier that I had had a tickover heat isuue on my MZ however, since I installed your ally rad it has not been an issue and as I mentioned I took it down to (Italy earier this year pretty warm there). I think that it is because it is much free'er flowing.
As an aside, on the original rad the fan only came on for a very few seconds, cooling only slightly the water in the rad. With the new rad this is not the case.
