Why are you losing coolant out of your overflow?
There could be several reasons. Under normal operation, the vehicle will experience this as the coolant heats up and expands into the over flow. A bad water pump, low level of coolant, as well as a clogged radiator could also cause this problem.
The overflow bottle may overflow if: 1. The car is overheating - this means after the coolant in the radiator gets heated up and expands it flows to the reserve bottle but the radiator doesn't cool down to suck back the coolant from the overflow bottle, but just keeps on sending coolant to the bottle. 2. You may have put excess coolant in the bottle - hence heated coolant from the radiator didn't get enough…
I have a warning light on my 1984 300zx it looks like a carousel or something on the right side of the dash what does it mean?
What does the flashing red light that looks like a water can under the maintenance required light mean for a 1998 Honda Accord 2 door coupe?
It has a tube between itself and the radiator. As coolant heats up, it expands. The expanding coolant goes through the tube into the overflow tank. Later, when the vehicle is shut off and the radiator cools, the overflow is pulled back into the radiator. The system is "closed", hence the coolant does not just "dribble away" when it expands like it did in vehicles many years ago.
After replacing radiator hose do you put coolant in the radiator and the overflow bottle or just the bottle?
Why does your '98 Saturn PCM not receive data from a new ECTS low coolant light flashing still with good coolant and sensor no apparant wire problems?
The engine coolant temperature sensor has nothing to do with the low coolant light. The low coolant sensor is mounted in the bottom of the overflow/filling reservoir by your washer fluid bottle. You will need to verify that the coolant overflow/fill bottle has coolant in it and if it does then the sensor is bad and will have to be replaced.
