well last time i tried using that method it didnt work n i ended up spending hours of pumping hoses n warming up/ cooling down etc. etc.
this time i've not actually tried that yet

ops;... just done the whole "let it get fookin hot, bung on cap, then top up when it cools down n level drops" so might try that tomorrow (means putting the viscous back on tho

)
thing is the car dont overheat or nuffin, its just that the temp fluctuates a bit when cruising, and runs hotter than usual in traffic... so unless this garage have done something SERIOUSLY wrong when replacing stat+waterpump i assume it's be the same as it was or even better perhaps?
