- 1-While refilling an 8-quart (7.57 L) system with coolant: Technician A initially puts in 4 quarts (3.78 L) of straight coolant and tops it off with water. Technician B fills the system with the correct mixture, tightens the radiator cap, and then checks for leaks. Who is correct? 2-While checking for conditions that might cause coolant electrolysis: Technician A places the positive lead of a voltmeter into the coolant and connects the negative lead to a ground. Technician B checks for the presence of voltage in the coolant with the ignition off. Who is correct? 3-Technician A says that if the PCV valve or connecting hoses become clogged, excessive pressure will develop in the crankcase and can cause oil leaks.
