Ever since I had a Techco twin screw blower installed, I keep occasianally getting the "check coolant level" displayed on my DIC. The level has been consistent, which is slightly above the full mark on the reservoir. Could they have not bled the system properly, and some air pockets are trapped in my cooling system? I also have the DeWitts A05A radiator with the Lingenfelter 160-degree thermostat. Either that, or how about a faulty Collant Reservoir level sensor or the resevour cap?
