Default water pump question on camry

I went to have my smog checked and the mechanic said to me I have a
water pump leak.
I changed my water pump about 1 year ago along with the timing belt
etc.

Can some tell if there is a leak by just looking? He pointed at
something under the hood
identifying the leak. I didn't see anything.

Another mechanic said its very hard to tell if there is water pump leak
by looking at it. You need to add water to the pump and do
something??????

If there is a leak can I go back to the previous shop that replaced my
water pump
and complain that it shouldn't wear out after 1 year, or he might say
the warranty is over??

who is right?
Thanks
Roger Vaede

There are primarily two ways a water pump can fail: the bearing wears
out or the seal leaks. Usually the seal goes first and cause corrosion
to set in, taking out the bearing. Improper belt loads on the pump
shaft (bearing) is rare unless the mechanic is not competent, but this
will shorten the life of the pump as well. Wrong coolant, tap water or
low concentration are not good for your cooling system.

Where is the coolant leak? Under the timing belt valve cover? The pump
can leak from the weep hole or at the mounting gasket. Assuming your
cooling system is properly filled (no air in the radiator). Does the
coolant level in the reservior drop?

Take it back to the original installer of the pump is probably the best
bet, especially if you frequent that mechanic. After 1 year, even
Toyota will tell you warranty is over ($$$$$).

These import cars need silicate-free coolant. So use Toyota red coolant
($9.99 with coupon) with 50% distilled water only. Now everybody sells
only prediluted coolant, and if that's the case (Toyota pink) don't add
any water.

Airtex has a video on the diagnosis of cooling system failure. Check it
out:

If it is a Toy pump it should be ok. Aftermarket stuff is junk. Go back
to who did it. Over the years Ive had nothing but trouble with after
market and I am just a car owner.

I would't paint with a broad brush on aftermarket parts. Most are
excellent, such as Purolator PureOne, Akebono ProAct ceramic and NGK
Iridium, but there are cheap junks if you buy the blue light special in
any parts store.

Toyotas don't come with Toyota plugs, they are either NGK or the
cheaper Denso with the same aftermarket labeling.
