Hello guys
Well, as the title sugests, I've got a cooling issue. This has been happening for a while but it goes away by itself. Decided to find out what the problem is this time. So, went to the car today, found a flat battery. The cooling fans had been on the whole night as one of my friends told me. Good, powered it up again and thought I should bleed the cooling system. Started the car, filled it up as needed and then let it run with the cap open. It reached 90 degrees on the dial and started boiling over

. The fans didn't kick in at all and although it never jumped 90 degrees, it was definitly boiling over. Also, when i stab at the throttle real fast it tends to die. Otherwise runs fine

.
Any thoughts?
