4.6 northstar engine just had motor swap because the other engine blew head gasket. My check coolant light keeps coming on but I noticed that it keeps spitting out the coolant though the over flow tube. Its not running hot or anything like that but it does stumble when I give it gas. Why would it keep spitting coolant back out the over flow tube. There is no purge value on the system. Please help thanks fast3254

Is it overfull, or at the adequate level with the low light on? I would either think it is overheating, or overfull. If the low message is on, and it is not low, disconnect the sensor in the tank. If the message goes away, replace the tank w/sensor.
