Overheated - panic stations?

Kroll · 20th December 2022, 14:27

My 1.8t ZT got a little warm on Sunday afternoon during a drive back from a hospital appointment. The temp gauge blipped into the red, the warning flashed up for a second and then immediately went back to normal.

I’ve not been well so only had the chance to check on things properly this afternoon. Oil levels seem fine, but coolant levels were way down. I’ve filled that up and will see if it goes down again.

There’s no sign of the dreaded mayonnaise, but I know that’s not the be all and end all of HGF diagnosis.

Is it likely the cold snap and fast thaw we experienced this last week could have caused a leak somewhere? Or is this just wishful thinking? The only other symptoms I’ve had are the heating taking a while to kick in, but I put that down to the weather.

What other checks and precautions should I take? I’m just looking for advice and reassurance really.
