Ashamed to admit it, but when I removed and replaced the rad on my 1987 plus 8, I connected the wires back to front and had similar symptoms. Fan was pushing instead of pulling through the rad.

Technical Hi All. My plus eight has the normal problem of getting hot when stationary. I have opened the rear of the bonnet 40mm and fitted an aluminium rad. Still have a slight issue. Before fitting an oil cooler a guy at LeMans suggested fitting a smaller pulley to the water pump to draw more water through the system. With a standard 97 3.9 hotwire I believe I may have room on the pump to try this, engine doesn't rev as high as a worked 4.6. However before I start machining a billet I would like to check the pump characteristics to ensure I don't end up with cavitation in the pump. Currently toying with a 10-15 % speed increase. Now the point . Can anyone provide a spec for the water pump, preferably with characteristic curves. Thanks in advance.
