Can anyone help me regarding airlocks on coolant system on a FL2? I've just replaced the thermostat and I'm struggling to get the top hose (pictured left) hot. I have ran the car up to temp so the gauge is halfway. The cabin heater is nice and hot inside so that is ok. I can squish the bottom rad pipe (pictured right) together as if the internal hose is touching together which suggests no coolant is in it but it does feel quite hot. Can anyone feel this hose on their FL2 once up to running temp and tell me how it should feel?

The coolant is at max level and the fan keeps coming on and off. When I squish both bottom or top radiator hoses I can see the coolant reservoir level wobble (suggesting I'm pushing air back into it). Thanks!!
