Check Test Coolant Condition Prevent Corrosion Check Your Test the coolant. set your multimeter to dc volts to less than (<) 20 volts. touch the black lead to the negative battery lead or the chassis ground, and place the red lead into the coolant. if the reading is less than .4 volts, the coolant is in good shape. anything over that indicates the anti corrosive properties of the antifreeze have. Take the dvom and check the alternator output for over charging. start the vehicle and hook up the test leads to the negative and positive posts of the battery and then check the voltage. most manufacturers consider 14.7 volts is over charging as anything over that the battery cannot accept and the stray voltage gets absorbed somewhere.
Engine Coolant Temperature Sensor How It Works Symptoms Problems How to test coolant. begin with a cold engine. remove the radiator cap and start the engine. set your digital multimeter to dc volts at 20 volts or less. when the engine reaches operating temperature, insert the positive probe directly into the coolant. rev the engine to 2,000 rpm and place the negative probe on the negative battery terminal. Set a digital multimeter on the dc scale for around 12 volts. attach one of the test leads to the negative battery terminal and submerse the other end into the coolant. then rev the engine to 2,000 rpm and read the voltage on the meter. if the test reads over .3 .4 volts, it means that the coolant is conducting too much electricity. Step 1. make sure you use a digital voltmeter on a low setting (like 2 volts). attach black lead from voltmeter to engine ground. allow red lead from voltmeter to contact coolant. do you have a reading? continuetesting. step 2. now, remove your battery terminals (at your battery) and repeat the the test. Did you know that your coolant can be damaging your engine, even if it test ok with a specific gravity tester or test strip? here i explain how and show you.
