Hi

In May, on route back to the UK, the red temp light started to flicker. I limped home, topping up every time the red temp light came on.

In June my mechanic changed the thermostat + coolant. Not sure if he just removed a hose and drained it, then filled without bleeding. They did not remove the front grill.

The blue header cap + fan belt are new (no slack)

Yesterday, the red light began to flicker again.

Checked the top up bottle (behind the flap) and it was normal.

No evidence of any hose leaks.

No coolant mixing with the oil.

Filled up the header tank bottle and, drove about 30 kms and then the red light came on again.

Checked the plastic top up bottle again and the level was correct.

Removed the small hose leading up to the expansion bottle, thinking it was blocked but it was fine.

Then I checked the header bottle and found it was about half full, so topped it up. Drove home (7 miles) and no red flickering light..

A friend suggested to remove the grill and radiator nut and top up with coolant as he said there may be an air lock.

Could it be an air lock to the radiator?

If so, should i remove the grill and nut and then top up the radiator?

Or, could the problem be elsewhere?

Any advice would be most appreciated.

Bleed it properly, front up and open bleed screw to let air out.
Make sure it's hot so the thermostat opens the circuit to the front.
