Default water pump reliability

I have a timing belt change coming up. I am VERY short on cash. I am the original owner of an 03 WRX. It has been very well taken care of. I never raced and I'm not a kid. All regular scheduled maintenance has been preformed on the dot. I did a search on this but didn't get a clear answer or I missed it.

Do I REALLY NEED to replace my water pump with my timing belt? It would save me 262.84$ if I don't replace it. I've heard the "While your in there" thing over and over. Ive also heard the WRX has a strong pump.

This is what my mechanic said...

I was forwarded your email about getting a quote on having the timing belt and water pump replaced on your WRX. I have attached a quote broken down into two parts. The first is for the timing belt replacement that includes replacing all of the front engine seals, ie front cam seals, crank shaft seal, and oil pump o-ring, timing belt, and one specific timing belt idler pulley that we see regularly. We always recommend replacing the front engine oil seals and that one specific roller while we are doing a timing belt service due to the fact there is such a high failure rate of those parts and the amount of labor saved doing them all at the same time. I then have the water pump estimated on a separate job line. Water pumps are not as common to fail on these engines as they are on others so I wouldn't say that replacement is necessary. It definitely is not a bad idea, but I wanted you to see what the break down of cost with replacing the pump and with out. The total at the bottom would be doing everything listed on the estimate with tax included.

889.06$ I can attach the pdf of the break down if necessary.

What is the official word in this?

Its not as necessary. I think it would need inspection to make the call. Why don't you do the timing belt your self. It would save you the money to do the water pump. Ask on the local forums for some one to help for beer and food. The gates kits and water pump should run 500 plus beer. Look up meatys tinning belt guide. He has a video and a how to on here.

yea the gates kits you can buy on ebay cost a total of $250-300 for everything, belt, pulleys, tentioner, waterpump etc. you shouldve just got the whole kit for the cost of the one pump it seems like.

it isnt do or die, however if you do end up needing it, you will be bending over again for the labor of what you could do just now for $200 while youre in there. takes 2 minutes to do and could end up saving you $1000 of labor in the future.
