In most cases a failed water pump will leak out of the bottom  hole when
the seals fail. Anothre way to test WP is to grab a fan blade and wiggle
it. I found a bad water pump while out driving once that way. It will
really move forward and back if the pump is bad. The easiest way to test a
thermostat is to pull it and throw it into a pot heating water on the stove
with a candy thermometer in the water. it should start to open 165-195
depending on the temp rating. I had a NOS sleeved stat in my car and it ran
great with new HD radiator and high speed fan, then it just began to
 overheat. tested the thermostat as described and it barely opened even at
boiling temp. replaced it with a non-sleeved stat and all is great.

You do need a sleeved thermostat to close of the bypass. If this stays 
open part of the coolant will not pass the radiator which may lead to 
overheating during stop&go/high speed driving.
The Smiths/AC etc. bellows thermostats can fail prematurely, on the 
other hand it can last for donkeys years. The soldering was done by hand 
so not very consistent and prone to faults in the manufacturing process.

Always glad go help. Another test is to remove the rad cap start the car
and wait go see if the water begins to circulate in the radiator when it
gets up to running temp. If the water just sits calm its not making it past
the stat. Anyway be careful to use penetrating oil on the nuts so you don't
break the studs on the stat Housing.

Good point Ira.

The studs can be an issue especially of the housing hasn=E2=80=99t been rem=
oved in some time.

I have sleeved the studs with a short length of shrink wrap tubing to provi=
de an insulator between the steel and alloy. Electrolytic corrosion doncha =
know! That=E2=80=99s the problem.

Cheers.
