Coolant seneor test

Can I see a re-post of the test used to check the coolant sensor? Also, if I just pull the sensor will I have a lot of coolant to clean up, or do I drain the coolant first?

I usually drain about a 1/2 gal of coolant or so from the radiator...remove the sensor, otherwise you'll get fluid from the intake. If the sensor is in the head at the exhaust manifold, you'll need to remove enough to get below the opening...maybe 1 & 1/2 gal. Take an ohmmeter and check across the connection tab and the base. If you have the stock sensor, it should read about 400 ohms at 100 deg F. Heat a small pan of water on the stove to boil and place the bottom portion of the sensor in the water and allow it to heat thoroughly. At 212 deg F or boiling, it should read about 100 ohms. If the readings from the sensor are close to the numbers mentioned and the console gauge is stock and functioning, it should read as designed.
