Once again, thanks.
My only arguement against that theory though is that the flow rate alters with engine speed. If there was a blockage then i'd pressume the flow of coolant woud be constantly poor? With the engine at 2000rpm, after a minute the coolant comes squirting from the matrix hose and maintains it once i've dropped the revs to idle. Only after 5 mins of replacing the hose and clip does it seem to drop again!
I've also noticed that my engine temp doesn't get higher than 90 and my fan never kicks in. Got back from a run today with engine temp at 90 and opened the bonnet, left the engine running for another 20 mins but the temp didn't raise nor did the fan kick in. Maybe it's just the ambient temperature thats helping to keep the engine cool!?
