Bravada V6-4.3L VIN W (1997)
Reading Procedure
Point the coolant concentration tester toward any light source and look into the eyepiece.
1. The coolant protection reading is at the point where the dividing line between light and dark crosses the scale. Antifreeze protection is the
scale on the right.
2. The temperature scale is reversed from a standard thermometer scale.
3. Readings on the lower half of the scale indicate solutions without enough protection.
4. If the readings are not clear, the measuring surfaces were not cleaned and dried properly. Wipe dry and conduct a new test.
5. Adjust coolant protection level as necessary.
