Hi
this is also my first post though a keen and grateful observer of the other contributors. I have a 1985 +8 with the 3.5 and needed to replace a failing waterpump about 1 year ago. I installed a davies craig electric pump with the temp controller and have been very happy with the results even on 35deg days in Sydney traffic. It is a tight squeeze and I made up a dummy from foam to ensure it would go in before buying the kit. The radiator and fan are still the originals and no fan overide switch has been required. Happy to provide more details if you are interested
Regards j
