Yes direct without coupling was what I was thinking.
I have ordered a new direct pump and fan from euro 4X4 as I have the original pump and a Landover fan that fits but may be over cooling???
The problem I am having is that it will only warm up to about 1/3rd on the water temp gauge and blow barely warm air even when engine is up to temp.
I was considering electric fan but I get your drift as the truck is mostly original apart from the rear body.
Looks like I'm well late commenting on your quote above, but it sounds to me like your thermostat is not working correctly.
I don't know your engine, but the principle is simple, the stat should stay shut from cold blocking any water from circulating around the radiator until up to temp.
Then it should open a little to allow some water to circulate thtough the rad until the whole system is up to temp.
If the stat is stuck open, then it will take a very long time to get up to temp, if ever, because there's nothing to regulate the temperature.
It sounds like your stat is either stuck open or its opening too soon.
Likewise, if it stays closed, once up to temp it won't release flow to the rad and she'll boil up.
The problem with a fixed fan is that the rad will probably be over-cooled meaning the stat will be (or should be) in the closed or almost closed position all the time.
If I'm right, and it's not closing at all, it will never get to temp, so there'll be very little chance of ever having hot (enough) water circulating the heater matrix.
The fixed fan will only make this situation worse.
If you haven't done so already, I suggest you get a new stat.
I said it before, but this a beautiful truck, and a major credit to you and the build.
