A stuck closed thermostat would make the coolant temperature symbol illuminate.
If the thermostat is broken in the closed position the engine would overheat rapidly. If it was broken in the open position the engine cooling system would not reach normal operating temperature and the heater would produce only warm air. Take the thermostat out and put it in a pan of water on the stove. When the water gets to around 200 deg F, the thermostat should open. If it doesn't it needs replaced. Observe carefully that you have not installed the thermostat upsidedown.
Remove the water supply hose from the top of your 2005 Chevy Cavalier thermostat housing. Remove the thermostat housing retaining bolts. Lift the old thermostat out and drop in the new thermostat.
The thermostat is broken. If it's not heating at all the heater element and/or it's fuse is broken.
The light passing from the water to the air through the curved surface of the glass causes the light to refract or bend. This bending creates an optical illusion that makes the straw appear broken or disjointed.
optical effect
water pump, thermostat broken fans, clogged radiator, broken hoses
This optical illusion is caused by light refraction at the boundary between the air and water. When light passes from air to water, it changes direction due to the change in media, making the pencil appear broken or disjointed at the water's surface.
bends as it passes from air into water, causing the pencil to appear broken. This phenomenon is known as refraction.
The stick appears to be broken due to light refraction at the interface between the air and water, causing the light rays to bend. This bending of light makes the stick appear disjointed at the point where it enters the water.
When light travels from water to air, it changes speed and direction due to the change in the medium's density. This causes the light rays to refract or bend, creating an optical illusion that makes the spoon appear bent or broken at the point where it enters the water.
Light refraction causes a straw in a glass of water to appear bent or broken.
When light passes through air and enters water, it changes speed and direction due to the different density of the two mediums. This causes the light rays to refract, making objects appear distorted, crooked, or broken when viewed through water. This phenomenon is known as refraction.
