New water pump.
I believe there are whole kits out there that come with the belt, water pump, CAS, and so on. You should look at those.
I defiantly do all of above, plus water pump, oring to water outlet on head (or block I forgot which) keyway. Not totally necessary but, valve cover gasket, upper and front lower hoses, front main seal new, rubber gaskets for the TB cover. And a few that I cannot remember.Quote:

Nothing would suck worse then going through the hassle of changing the timing belt only to have to do it again in 6 months when the water pump decides to give up.
If you have not done it yet, find and read the instrucitons for changing the timing belt and you will see why we say to do everything else when you are in there.
The PO told me the water pump went out on him and he'd replaced it. But he didn't replace the belt! (since it still looked new and all):rolleyes:Quote:

I'd do it all if it were my car and I was planning on keeping it for awhile, especially since the history is cloudy.
I would rather have someone replace the water pump and not the belt then make the stupid choice I made last time of replacing the belt without the waterpump. A broken timing belt is just a tow. A broken water pump can be much worse. I didn't really understand that back then. I will be doing both this winter.Quote:

Yeah, I don't want to get caught being "penny wise, pound foolish". Speaking of, I still can't believe he didn't replace the TB!
Once a belt has been run for 5 minutes, IT IS USED....

Good cheap stuff.
Blackroadster put this together and it's a pretty good checklist for a TB R&R... I can say that when I did mine (had it done), I took care of all the internal stuff and checked the other easy-to-get-to stuff myself. I had already done the CAS o-ring and heater hoses, and the remaining belts & hoses looked fresh, so we didn't mess with them. Same goes for plugs and wires, etc... at least with this list, you shouldn't overlook anything. Also, one of my TB idler pulleys was fouled up, so I replaced both of them. I don't remember how much they were, but it was pretty inconsequential in the grand scheme.

The timing belt is pretty involved. Lots of labor is involved in it’s replacement. I’d recommend having a few things replaced in the process.
This list is extensive but most of it is right there when you have to disassemble everything anyway to do the timing belt. It’s preventive maintenance. I’d rather replace these common failure parts now instead of having to replace them later and pay for all the labor all over again. Prices are for parts only and subject to change. Most prices come from http://www.trussvillemazda.com, which has the best prices I’ve seen for Genuine Mazda parts. Labor could range from $300-$500. Best to do it at a tech day for the price of some Pizza and Beer.
