Liquid Filled Gauges

One thing to keep in mind if you go to a liquid filled gauge. They are filled with glycerin which is heat sensitive. The hotter the gauge gets under the hood the thinner the glycerin gets, giving you a "false" low pressure reading. Make sure when you're checking the gauge in the engine compartment you do it with the engine compartment cold.
