No. If your vehicle can pass an emissions test, chances are that it's just a bad sensor.
if your vehicle has computers, this can cause check engine light to come on,as a coolant leak ends up sending trouble message to computer
it may be a defective sending unit or sensor.
The yellow radiator light on your Honda Accord is an indicator of low coolant in the radiator. The red radiator warning light is an indication of the engine overheating.
The temperature light comes on in a 1992 Chevy Lumina when the temperature of the engine reaches the boiling point. The light may also come on if the transmission gets too hot. Usually a leak in the radiator system will cause a loss of fluid and lead to the temperature light, but it could be anything and must be checked.
There is a valve called a petcock along the bottom edge of the radiator. Its used to drain the radiator. The low level float or sensor being stuck or bad is a more likely cause of the problem that a wrong mix.
The leak could come from: hoses, punctured radiator, split gasket...you can put tracer dye in the coolant and search for the leak with a black light after you clean the engine.
It would cause light to refract differently because the angle at which the light hits the glass block would alter and there for the way the light refracts would also alter.
Coolant leak possibly no fluid in radiator, hence the picture of a radiator.
I have a 2000 olds alero and the signal light only work sometimes, What would cause that?
what would cause the ADVTRAC OFF light to remain on on my 2005 ford explorer
The heat bends the light, causing objects to look distorted, and therefore the fireman's pathway. Just like the light above a radiator is distorted by its heat because light travels slower in heat.
Never heard of a TLC light on a car.
