RE: temp gauge

["Dennis C." <dennis.2914@xxxxxxxxx>]

I don't know what the factory gauge range is however it is easy to 
verify the reading on the Autometer gauge.

With the engine cold take the radiator cap off, insert a thermometer 
(many of the cooking thermometers will work fine, just don't tell your 
wife)

Start the car and let it warmup, compare the reading on the thermometer 
in the radiator to the Autometer reading.

Another way is with a hand held IR thermometer that you can point at the 
thermostat housing.

Even though 210 degrees is a very long way away from boiling at this 
temperature the thermostat is fully open and you are getting as much 
cooling as possible from the radiator.

You can check the back of an antifreeze jug to get an idea what 
temperature you could boil.

If you don' already have one it is a good idea to use a high flow 
thermostat such as the following Milodon unit that is available from 
many sources:
