I have an 03 Mitsubishi Shogun 3.2 DID Warrior. Its a diesel and an automatic and has done 80,000 miles. I regularly tow a trailer and a horse. Up until last week it has always been fine. Last week it went to overheat. I managed to pull over and let it cool down. When I checked the radiator it had no water in it. I refilled it and have regularly had to refill it. There is no obvious leak and no wet patch under the car when it has been parked overnight. A couple of days ago I put radweld in the radiator and yesterday when I towed the temperature gauge rose almost to high. When I checked the radiator and reserve tank later, they were still full! I took it to the garage. They were adamant it was the head gasket, but on doing tests it showed it wasn't. They were then scratching their heads as to what it could be. They said it could be the radiator or the viscus fan? or the water pump. They said to change the radiator to see if its that first, and then the fan if not and water pump. I said I don't want to pay out for things if its not the problem, but they said there was no other way of knowing! I don't know what to do now as I'm none the wiser and I just want my car fixed.

You started out with a coolant leak that could have been located and repaired. Now that you have added the sealer, you will likely have to change the radiator now even if it wasn't your original problem. There is no such thing as "mechanic in a can" and the only ones these products benefit are the people that sold them.
You need to pressure test the cooling system and determine where the coolant is going.
