UTI chapter 5 cooling system questions
with correct answers
What vis vthe vpurpose vof vthe vcooling vsystem? v- vAnswer v- vTo vmaintain vsafe vengine voperating
vtemperature.
What vcauses vrapid vwear vof vengine vparts? vWhat vcauses vslugging vof vthe voil? v- vAnswer v- vExcessive
vhigh vand vlow vtemperatures vcause vparts v to vfail. vLow vtemperatures vwill vcause vslugging vof vthe voil,
vand vhence v component vfailure.
How vdoes vthe vradiator vget vrid vof vheat? v- vAnswer v- vCoolant vis vpumped vthrough vthe vcore vand
vair vpasses vover vthe vfins, vwhich vincrease v the vsurface varea vof vthe vcore, vto vdissipate vheat vto vthe
vatmosphere.
What velse vdoes vthe vradiator vhelp vto vcool? v- vAnswer v- vSome vradiators valso vhelp vcool vthe
vtransmission vfluid.
What vcomponent vin vthe vradiator vcap vcontrols vpressure? v- vAnswer v- vThe vpressure vvalve vin vthe
vradiator vcap.
How vmuch vwill vthe vradiator vcap vraise vthe vboiling vpoint vof vcoolant? v- vAnswer v- vThe vboiling
vpoint vwill vincrease vapproximately v3 vdegrees vFahrenheit vfor veach vpound vof vpressure.
What vdoes vthe vcoolant vdo vwhen vit vgets vhot? vCold? v- vAnswer v- vThe vcoolant vexpands vwhen vit
vgets vhot vand v contracts vwhen vit vgets vlow.
When vcoolant vexpands, vwhere vdoes vit vgo? v- vAnswer v- vWhen vthe vcoolant vexpands vit vgoes vinto
vthe voverflow vtank v(expansion v tank).
