Rising water temp issue

Hi fellas,

I have zero clue so hoping to tap into some of your knowledge!

I noticed earlier when stopped at some traffic lights on an uphill incline that my water temp gauge was rising, nearly to max. When I moved off, it dropped right back down and sat at the middle. I continued on with my journey for a good 15 miles with it stuck at the middle as it normally should be and didn't notice anything again for the rest of the night, the rest of my journey involved uphill, downhill, flats, twistys (wales!) and seemed ok.

Any ideas what could've caused this? It's also started to flash the central warning light on the dash under braking only which then disappears again under any form of acceleration (dunno if related - read it could be time for a brake fluid flush and change?)

Any help much appreciated.

Have you had any cooling related work done recently?

First thing i'd do when its cold is check the rad cap, also check the coolant levels, it should be full in the rad and

be around half full in the overflow tank

Check the brake fluid level, a low level can bring the red triangle on

Do as Dunk said and report back, it takes a fair amount to get the gauge to move up to the max or even away from the middle. I suspect a small leak and loss of coolant over time, or something (rad cap etc) isn't allowing the system to be pressurised.

Check your fan clutch for the over heating.

Warning triangle, as above check brake fluid level.
