Component Testing: Tercel

1. Drain coolant from radiator and remove TVSV. Immerse threaded end of valve in container of water with thermometer. See Figure.
2. Using ice, cool water in container to below 45°F (7°C). Check that air flows from port "J" to port "M" and "L" and from port "K" to port "N". Heat water to 63-122°F (17-50°C). Check that air flows from port "K" to port "N" and "L" and from port "J" to port "M".

Apply more than 3.5 in. Hg vacuum to port "S". Plug ports "R" and "Y", then blow air into port "T". Air should flow out ports "U", "V", and "Z" and, on Calif. models, "W". With no vacuum at port "S", no air should flow.
