    Rick,
    I might've missed it being mentioned, but are you 120% sure you have a full cooling system? I've had occasion to drain my entire system a few times recently while fixing a leak, and it has been VERY difficult to get it to burp a major air bubble out of the system. I tried filling through the heater hose, pulling the thermostat, blowing in various hoses, etc. Anyway, with that air in there, you'll get no circulation, and no cooling.

    The thing that worked best the last time was the old trick of parking it on an incline when filling/testing/topping. That way any air makes it way to the top of the system and out.

    I don't know the capacity offhand, but before I solved the problem, I somehow convinced myself, even though I knew better, that I had enough coolant in there. It was probably near a gallon. It definitely takes closer to 2 gallons! So I spent some hours chasing a bunch of ghosts. It'd be easy to check by draining into a container and seeing how much coolant is in there.

      Which water pump

      I pulled the radiator today for service and took a photo of the water pump.

        Radiator

        Here is a picture of the radiator. You can see that it has fin rot and has been worked on before. It appears that someone replaced the radiator using two sections of core. I am guessing it was overheating causing the fins to become so brittle.

          I think it was that way from the factory. My original radiator looked exactly the same way - fins had a vertical split.

          The fins corrode over time, not sure you can attribute it to overheating.

            Get it radiator repair guy and have it recored. Not such a big deal and a whole lot cheaper than buying a replacement.

            That will add to your abnormal heating problems but may not be the sole cause. Less likely to be the pump at fault.

            Cores are replaceable, the header and footer tanks are not so much.

              I took the radiator to a shop I have used before and he could not locate a core for it, it would be a custom core and I was quoted a price of $325.

              So unless someone has a core number for a Land Rover that is good in the US. I guess I will have to buy one from our hosts.
