Re: Engine Temperature Gauge Reading

The 150 thermostat is probably an artifact of the time when alcohol was used as an anti-freeze. It has a low boiling point and needed the low temp stat. It was common for the alcohol to be replenished during the freezing weather season. Cooling systems were drained and straight water replaced the alcohol for warm weather driving. An anti-rust and water pump lubricant were recommend to be added when the system was serviced with water. This recommendation was not followed by all all the time and lead to a lot of internal rusting. I was running a 140 temp stat in my formerly owned 47 Custom Clipper. It was a NOS bellows type. This worked well in Austin's year round warm weather.
