Could be an air lock and need's bleeding. And check out the viscus fan clutch.

I've just been talking to the garage about mine and he said they are 'a pig' to bleed properly.

Probably that.

well, it's overheating if i got stuck in heavy traffic,,
yesterday, 10 minutes after i started up the engine the heat indicator turns to red,, strange huh? it's the first time hapening like that,, is it because i used it to travel out of town 2 days ago??? it's pretty far,, around 200 km,

btw i've changed the viscus fan clutch,,

Have you checked the new one works? These viscous units can fail, if they are stored for any length of time flat. They must be stored on edge.
