Looking to change the timing belt on my 98 4door 126,000 & after reading some post thought I would change the water pump at the same time I don't think ether has been changed, because if the old owner got the same $700.00 price that was posted, I don't think he would have spent that much, on the car.    Have seen several pumps on ebay & I am sure some of the knock offs don't fit right, so what brand should I get.
  I know that the Gates belt is the way to go... but water pump?

Also does anyone know were to get the outside R & L door molded belt Weatherstrip Seal 

I don't know of any difference in quality of any of the various brands of water pumps.  I have seen or used several different brands and they all seem to work and fit as they are supposed to.

GMB of Japan...I never had any of theses pumps fail prematurely.
