My wizard is a rebuilt viscous but that is road only. Bighorn though its a toss up between electric and viscous. I didnt slice open the radiator but from the top of the zigzag to home used 6 litres of water after attempting the bog in slippery forest a little quick. High centre between ruts stops you very quick. Able Smith radiators tested it in there tank and at 0.5psi air was coming out in 7 places. Went to a half nissan pulsar fan running continuous and it was ok but not great. I overheated on the zigzag but that was towing a zuke at the same time. Went back to viscous and within 6 months all the blades fell off and more bruises in the radiator.(also the radiator bought online from a well known Auckland wrecker was near solid with mud with a coat of fresh black paint to disguise but thats another story) No leaks this time. Then as I was wrecking Lewises Mu I put the radiator from that radiator and fan into the bighorn. Its a 14 inch aftermarket fan but not 100% happy with the result. It climbs to 100C on hills but never higher but at the same time doesnt eat radiators. I havnt got round to the thermo switch yet and might not considering the type of use that truck gets.
If you are interested I do have a nissan pulsar twin fan here that should fit your truck. Its too wide to go in the ubs55 but looks like it would fit the wizard so should fit your truck providing the thicker radiator doesnt use up all your room. You would have to figure out how to mount it but shouldnt be hard. It shifts a lot of air
Sanding your knuckles before starting work can help. That way you cant skin them
