5936 1st Gear July 6, 2012 Share July 6, 2012 Isn't this a reflectometer? What is the reference index for 50% coolant / water mixture? Link to post Share on other sites More sharing options...
Yeobh 4th Gear July 6, 2012 Author Share July 6, 2012 Yes, it's a refractometer designed with scales for reading anti-freeze coolant ( ethylene & propylene glycol ), washer windshield washer liquid and battery sulphric acid SG. For 50% concentrated EG the indicator line on the scale is on freeze temp of -36 deg C ( 107 deg C boiling temp) Most mech are using hydrometers for testing coolant, for higher accuracy many are switching to using refractormeter .

I quickly asked him how come never use water to flush out the old coolant out. He say no need. Flush already , still have old coolant inside.

Toyota long life coolant is premix and no water to be added. Usually the flushing off the old coolant cannot use water have to use the premix coolant to do it.

He just didn't do a thorough job. A thorough flush would be to bring the engine to operating temp, so that the thermostat is open. All the coolant inside the engine is free to move out to the radiator (even those in the heater core and going to the throttle body) and be drained off somewhere. Then new coolant can then be replaced more completely. By opening the valve at the radiator, you just draining about 1/3 of what the whole cooling system is holding.
