I have a 1996 model petrol "80"series. Could anyone advise me of the expected life of the radiator hoses. I have been told that because of the newer rubber compounds together with the use of coolant such as anti freeze anti boil hoses last longer than in the old days. But roughly how long? Some hoses are impossible to change without removing the inlet manifold which seems a very big job, so I only want to do this when neccessary, but not after a blown hose!!
Thanks in advance for any help.

I've changed mine 3 times in the last 8 years. Not because they needed it , but as a precaution. I also carry a spare set .

I have a 80 series and I waited until after 100000km and then while preparing for a desert trip I changed the hoses and kept the old ones with me to be sure if I needed one I knew it would fit and I had already had a practice run at changeing them.

The 80 has now done about 280000 and I still carry used hoses but would change them again before going to remote.

It’s a hard one to pick,

A good way to juge it to look for split’s/ cracks in the hose periculi around the hose clamp’s also feel the hose and then compare it to a new one, It’s hard to describe but you should be able to make an assessment of the condition of the hose.

You will probably find a lot of the hard to get ones are accessible when the car is on a hoist

The radiator hoses should do 150,000k’s happily heater etc a bit more maybe but it’s a bit hit and miss after that.

You wonder why they put some of them in the positions they do and why not use ½ or 1 inch 316 stainless steel line instead which will never need replacing. Then you remember it’s all about cost, weight and most servicing schedules stop at 150,000 design never look past that and they don’t need to replace them so why do they give a stuff.

Can't tell how long the Missen ones last, 'cause they're missen........

This could lead anywhere, thankfully we're still sober. .....or at least I am...

I actually don't drink inkahol, for medical reasons. But I'm so silly that nobody knows :))
Actually both Toyota and Nissan make a good product these days. I prefer the toyos because I don't want to go missin :))

I have an 80 series Turbo diesel L/C 1991. Changed the original hoses last year. I have always kept spares with me. I don't think that the new hoses are as good as the originals. I now keep the originals as spares also

Should get a good few years.
Look for expansion and splitting.

But I usually change mine after every 2 years for a big trip.
And I check every one, not just the 3 in the kit.
Got caught once with a little radiator hose like you describe going one night in the middle of nowhere. No torch and only basic tools.

Decided after that it was easier to do it at home with all of the tools and in the shade, and not the pressure of having to get it done ASAP.:-)
Take the old ones with me as a spare.

For offroad travelling, we recommend changing the hoses at 100,000km, with the new spares they have [or should have] and keeping the old ones for spares, on the 80 you dont need to remove the inlet manifold to replace the small hose, it can be done in car reasonably easily.

Life expectancy involves coolant levels, stray current, static electricity, cleaning fluids, etc etc in under bonnet life, and are best treated as preventitive maintenance issues, rather than vital signs appearing issues.
