It seems there are always 3 ways to skin a Rover so I'm more or less sharing that a simple/cheap toggle switch on a efan that I flip on before the temps start to typically climb has done the trick. I'll add that I'm running a 5-6 year old $500 Proline rad from RN, a HD clutch fan, good t-stat, and fresh coolant. I also monitor my temps through the ECU with an OBD2 app.
This is why I stopped messing around with all of the guess work and just spend a lot to get a setup that I know works. Honestly, I’ve probably spent 20 hours trying to isolate issues on a single defender, and have done that several times on other defenders. There is no one common issue.
I even switched to a RRC 11 blade fan and fan clutch on my D90 which was inadequate. Electric fans fixed that one

Jimmy, when you are out next, let’s hook up my trailer and go up I70 to the Eisenhower tunnel and see how the E-fans do on the way to camping! I’d love to see how they work for others! I should have crap dialed in by then for myself if need be. either way, I’ve got a couple sites to show you and the fam that I think you’ll like.
If I still had my D90 I would! I don’t think my 300 Tdi 110 could hit 50mph on flat ground towing a trailer
. My 110 has an Allisport radiator and mechanical fan which seems to work fine. I’ve never had issues with diesel fan clutches or radiators.
