i moved the rad to the back in our truggy with the stock water pump. on the flat is manages, but imagine on a climb or descent. the height of the water loop is massive for the water pump. i have a davies craig electric water pump but i haven't installed it yet. i think it can cope with short tracks in winter, but come summer, it'll definitely need the help. there's an old thread on here about installing DC EWPs.

I run a second radiator on the back of my GU ute and I just plumbed it into the heater hose inlet/outlet. This works fine. You don't need to have pressure as much as you need the extra volume of water. This makes it heaps simple and the engine still works exactly the same. I also made sure I used a factory radiator for the rear as I can change it for the front if I damage one. I got this advice from Bob Thompson at Bayswater rd Radiators here in Townsville. He's been doing stuff like this for years in burnout cars and also on modified troopies that are tour buses. After running mine I felt the rear radiator and I have no doubts that it works a treat. You don't need much of a gap between the cab and the radiator either as long as you have good thermo's.

I just realised that you are just running the one radiator. The water pump is more than enough to push the water from engine to radiator and back. Climbing and desending will at most only slow down the flow. This won't hurt your engine at all. The most it will do is allow a bit more time for the water to cool in the radiator.
