Water pump advice needed
 

'85 CJ-7 with an '86 AMC 360 under the hood:
My water pump just gave up the ghost. Considering my options, I see
high flow pumps such as the FlowKooler out there, but they are more
costly than stock pumps. Does anyone have good or bad experience with
such a thing? Are there any good reasons not to use a high flow (and
high pressure) pump? The ads recommend a high flow thermostat, too.
What would be the consequences of not using the high flow thermostat?
I've never had overheating issues with my stock pump and 4 row
radiator. Even on the hottest of days at the slowest of crawling
speeds, my temp needle tops out at about 2/3 scale. Would it be a waste
of money? My main desire is dependability and longevity.
Thanks.
Mark.

I use stock pumps, and most parts stores guaranteed them a life
time. I spin them pretty tight, too: http://www.----------.com/pismo.htm

Re: Water pump advice needed
 

The high flow thermostats that I have seen are 160º. Your engine won't be
hot enough, with the consequence that it might run poorly and -will-
accumulate excessive water and other nasty combustion by-products in the
crankcase.

Automotive water pumps don't really develop what you would call "pressure".
They are more like a "circulator", such as one would use in a hot water
residential heating system. If you were running too hot (which you are not)
then inadequate circulation would rarely be the problem. It would more
likely be inadequate air circulation, or an obstruction in the water part of
the system, which a high flow pump wouldn't really fix.
