Hi, Seems to be that I've air in my coolant system as the coolant temp is going up to 110degC after a cold engine start before the thermostat opens. Once the thermostat opens is the temp steady around 90 to 100degC. This sounds for me like air in the coolant. Can any one pinpoint (ideally with a photo) where the vent nipple is located. Easy access? Or other rootcauses for this phenomenon with the coolant temp? Thanks, regards Jan
