Add coolant until it's at the high mark on the tank if needed. , coolant will reach a level at which, as it climbs to normal operating temperatures, it expands to create pressure in the system. I did that today and the issue is still there. Power seems fine, AFR looked good, and everything else seemed normal. I just noticed that the level of coolant on my bike has dropped quite a lot and is now below the minimum mark. Cooling system service is particularly important on 6. If the coolant level is low, it may indicate a leak. Is it normal for engine coolant levels to lower in the hot summer? Basically about a month ago I checked its levels and it was near empty. 75 feet (NRC staff infers that this elevation corresponds to approximately 21. Is normal for coolant level to drop due to the temperature. If you don't have antifreeze but you need fluid, add distilled water,not ordinary tap water, so mineral deposits won't build in the radiator and cause corrosion or blockage. The effect of the oil shutter position on indicated airspeed and oil temperature is shown in Fig. no one else. As long as the level of coolant is steady between the "low" and "full" marks, everything should be just fine. Good answers from Bruce A McIntyre and Norman Irving. While other engines may not suffer this particular problem they could still benefit from a low coolant level indicator. Hope this explains why and when the level changes under normal operating conditions.
