The past few times I've started my rig (cold weather), I get a 'low coolant' light and buzzer. The alarm sounds for 1 - 2 minutes then stops. I've checked the coolant reservoir and all is OK. I had the lower crossover pipe replaced last summer and coolant system flushed and refilled. I also had to add coolant when I had to replace my leaking heater core. I've put approx. 1,000 miles on the rig since doing the heater core.
Could I still have some air trapped in the system? I understand that will cause the alarm.
