Instruments - Temperature Gauge Overshoot
REFERENCE ENGINE NUMBER 029 (REVISED) DATE 03-27-87 MODEL RA, RN
TITLE - 22R-E ENGINE TEMPERATURE OVERSHOOT
Double Valve Thermostat
Some 1984 pickup trucks and 1983-1984 Celica models, equipped with 22R-E engines, may experience a condition called "temperature gauge
overshoot". After starting a cold engine the temperature gauge will indicate a higher than normal engine temperature for a short time just prior to the
thermostat opening. After the thermostat opens, the temperature gauge will return to the normal range. A new double valve thermostat has been made
available to reduce temperature gauge overshoot. (See illustration below)
