Does it matter which way the coolant flows through the matrix?
As above, I got some -12an hose to supply and return the coolant from the matrix. I got 2 lengths and cut 1 to see what it looked like. By chance the cutoff part that was left fitted in the opposite way from stock (meaning a reverse flow through the matrix) so I was just wondering if I would get away with it as is or if it needs to be as per stock for any particular reason?
I don't want to waste a perfectly good bit of -12 for nothing
Just speculation, but it's possible that connecting the hoses the "wrong" way round would inhibit the flow of coolant via convection. I'm not sure where the coolant pathways lead, and specifically the relation between the coolant pump (which will drive the coolant much more strongly than convection flow) and where the pathways that feed the matrix come from. Like in the thread Jos linked to, this *could* cause the matrix to only chuck out warm air rather than hot.
