Yes, i'd really appreciate that, thanks. I'd like to know what i'm getting myself in for before I go draining all of the fluid out.
How hot on the temp gauge does it get after a few hours with the heater on? Does it give you heat in the cabin straight away?

Its probably not a bad thing that i'm choosing to do this soon.... I noticed last night that my water pump is getting noisy, so i'll have the fluids out anyway.
