Would be a manual, only made auto in the petrol and turbo diesels, only the 100 series non turbo diesel come in auto or manual.
Wayne, If you havent been playing in the mud and you havent filled the fins with seeds/grass/mud etc then my guess would be either the thermostat isnt opening all the way so is ok at lower revs allowing enough cooling but not at higher speeds. Id go the fluid clutch coupling first, either pull apart and replace the fluid (this is also not a definate as the spring on the front of the coupling could be stuffed due to age, or Id but a new one. Personally I would go genuine, yes they are alot dearer but have heard of people buying after market ones and having the same problem, I was even told this by the spare parts
shop I was going to get myn from and he could have easily have made some $$ from me but said go genuine. This is an extremely common problem on all the 80 series. Some people say the clutch fan doesnt lock in when at highway speeds, that is crap, They will lock in whenever they need to, some vehicles you can even hear them cut in, some sound like a jet winding up and the same when they unlock, its all detected by the metal bi spring that runs across the centre of the clutch coupling at the front detects the temp of the air flowing through the radiator onto it, when the air is hotter then the setting on the spring it does its job unlocking and locking when ever needed. Normally toyota temp guages only move 2 to 3mill either way once they hit there normal runnning temp on the guage, for them to move more then a couple of mill indicates possible problems.
Check also if the bottom radiator hose isnt sucking itself together, possible if hoses are old or are cheap crap non genuine replacements, they are generally very thin where as genuine are very think, I wouldnt touch one if it has the metal spring inside as they break up with age and guess where they end up ??.........Regards Steve
