well yes it does have a radiator a land rover one but when i stripped down the engine it didnt have a thermostat in it so i put in a 82o one and i didnt think anything of it cool=ing system needs flushing so will try that and also the fan is a manual turn on so i click a switch when i want them on which i jut leave it on all the time!

Do the heaters blow hot?

yes they do although the demisters are not connected so hot air does blow into the engine as it has a series 3 heater and 2a heater in wing and bulkhead but there is no intake in wing it comes out of engine bay!
FIRST make sure it is really running TOO hot!#
Even 82 degrees if PD hot. You will be scalded by water that hot.
You simply MUST ensure that the temp gauge SENDER is THE VERY ONE that belonged to the ORIGINAL ENGINE, because the Ford one WILL NOT give a true reading, never ever, no way, no how not even if Slob casts a spell on it.
Geez ..... people must learn that senders and instruments MUST MATCH or they will not work right.

yh i know that all done
Basically, if it doesn't boil up, you don't have a (serious) problem.
If the cooling system really is duff, it will BOIL when worked hard, especially at low road speeds, like low range, big trailer, steep hill.
The optimum temperature for a diesel engine to run at is VERY HOT, the hotter the better in fact. The fact we run them at about 90 degrees C is simply because we use liquid water as the coolant medium. Some racing aero engines were cooled by deliberately boiling off the water, so the engine ran at well over 100 degrees C. This is not a good system, as steam pockets form, the areas round those go red hot smartish, and at 400 mph about 1,000 feet from the ground that is a bad plan.
People with air-cooled diesels such as Magirus Deutz would be horrified to find out how hot their cylinder barrels get under load. SIZZLING hot. Even the V W Beetle engines got way hotter than 100 degrees C.
If it ain't boiling up, don't fix too much.

What size is the oil cooler and where is it located? The crappy twisty-pipe oil cooler fittied to military IIas ain't up to the job.

its infront of the radiator bhind the grill and without lookin as its in a garage its a twisty pipe one i think!

an its ex miliatry so maybe
wtf is that statement based on??
ave seen FFR landies running statically fer hours in hot climates and never had a problem with them cooking up or suffering from hot oil.
perhaps you'd care to expand on yer all encompassing statement and furnish us with some factual evidence.
of course if the oil is really old then it would be thiner and heat up quicker which would lead to problems , but that would be driver error and fook all to do with the oil cooler not being up to the job

Liquid Nitrogen? Sorry, feeling a bit strange after sniffing the latest dripping fluid...
