Joe n Mel
sounds a lot like mine, started heading up from Katanning, fine down low speeds and slowly worse as the days went by, started to get hot at 110 in cold RAIN ..............
1st did thermostat in perth
, it was not opening fully, better but still getting hot.. (June)
2nd fitted sh radiator from wreckers in Perth
, helped heaps, made it to Tom Price
... Got hotter at Broome
Long story cut short.. Broome
, Alice Springs
and halfway up the Tanimi for 3 months, was summer by then and all started getting hot again...soooo..
Got brand new radiator and fitted, new thermostat (again) and complete set of hoses and belts and re-oiled up the fan clutch and fitted watch-dog.... went heaps better but could not handle the REALLY hot days with A/c ....
Travelled back up to Darwin
and back down to Booraloola and got a brand new fan clutch and it is as cool as a cucumber now, loaded, ac, 3 kids and camper ....
So from my experiance and all other posts i have read..... get a brand new radiator (exactly the same "original"), new t/stat, new hoses, new belts, new coolant, and finally buy a NEW and TOYOTA original fan hub, dont touch it just install as is and providing you dont have a cracked head you will have no further problems, if the head is cracked you will still need to do all above anyway if you want it to last....
Cheers matey and good luck......

Going with a new water pump tomorrow. I've done 200,000k in the beast and not touched the water pump so its due anyway. Bit of a job pulling off the timing belt. Did the water pump in a 40 series about 5 years ago, a 5 min job, didnt have to touch anything, pull off bolt on new one. Anyway, I will use a genuine water pump and if that doesnt work, hmmm, I'll have to think some more . . . .

in all my 40 yrs in the mechanical trade ,I have never seen a water pump
with a slipping impeller or the pump itself causing an overheating issue
other than a leaking sealing causing loss of coolant .
, yes fan clutches are a big problem on toyotas bye only genuine .
