They touch WATER.(coolant)

Water wears away rock,changes it to sand.
water jets can cut through tough materials very quickly.
Plastic is relatively soft,and degrades with age.
Also,there's more than just coolant circulating inside a engine's cooling
system.(particulates,rust....)

no, particulates wear away rock.

and they're typically used in conjunction with abrasive powder when
cutting metals. at 60,000psi.

this is not the case with a vehicle impeller.

impellers on a honda are not plastic. nor are the casings.

there can be from time to time, but they don't continually circulate,
they settle in places like radiators and the lower channel of the
cylinder block.


bottom line, i've seen a whole bunch of honda water pumps, and none
evidenced any wear. including the 305k mile one off my old crx. that's
305k miles on the original water pump from new. it died by bearing/seal
failure, not impeller wear.

Hi Guys,

Justed wanted to let everybody know that it was the fans......The
radiator fan was just busted (barely turning at all) and the condensor
fan would run for a moment then shut off.....if you take your hand and
slightly turn the blade, the motor would come on again....I also
changed my temperture switch while I was at it......Thank you all for
some very good responses....Allot of knowledge in this group.

excellent that you took the time to follow up. it's a great help for
the archives.

It can be any or all of the things already talked about here, I would proceed in the following order:
Check coolant level cold - make sure rad. is full as well as coolant res.
Warm engine up, then watch to make sure the cooling fan comes on, it can take a little while, but the gauge shouldn't go beyond about 1/2 way to hot. After that you can try switching on the A/C - BOTH fans should be running when you switch it on.
Assuming that checks out ok, it could be a plugged rad. or bad therm. or bad water pump.
I've been working exclusively on Honda Accords for approx. 12 years and I've seen SEVERAL water pumps that had the impeller corroded away to the point that the flow was insufficient! It's usually caused by improper coolant (always use honda fluids!).
I'd replace TS first, and flush Rad. and change coolant. If that doesn't work then you might want to look into water pump.
Note: If you change water pump replace timing and balance shaft belt while your in there since you have to remove them anyway.
Hope that helps you!
