I recently bought a P38 Rangy diesel 2.5 after a long break from Land Rovers, and realise i may have made an error in thinking the 2.5 is up to the job of towing a double horse trailer. Have had the 1996 model for two or three days, had no problem with it driving without load on the flat, but having tried to pull the trailer plus one pony up a steep hill today, it rose rapidly in temp before hitting the red. Having let it cool for an hour and topping up the fluid (the expansion bottle pressurized, vent pipe spat most of it out), it then got me the 20 miles home, with the temp graduallydropping more and more as I got closer to 50mph going back. It now appears that it will run fine, unless put under load. Is this just the start of a cracked head or gasket going, or could it be a blocked pipe or similar? Would most forum members say that these 2.5 P38's are suitable for towing a double horse trailer on a regular basis?Thanks
