sorry gauge

Yep sounds pretty normal to me, lot of strain on the cooling system in those conditions.

Cheers

yes it will get hot towing a 20 ft van on a 40+ day,
have much the same combo and always tried not to tow on days like that,
either left early in the morning..dark.. or another day..
always watched the BOM as departure day got closer,

lots of towing vehicles on the side of the saturday and sunday

Hi Andy,
It says a lot about those engines that they can tow that sort of weight on a 40 deg. day at 90km/h and still sit in the normal zone. I would not worry, you found the solution, ease back to 90Ks as you said. Give the old girl a kiss (car that is) and thank her for a good job well done.

Remember there is not as much oxygen per cubic foot of air on a hot day so the engine has to work harder to get the same job done.

I own an 96 80 ser. with a 1HD FT engine and that is what I find.
regards, Bruce.

Hi,
My old girls does the same.
It has a near new radiator and new coolant and only small driving lights on the front. I have noticed that if I travel at 95-100 in fourth it is fine, 105 in fourth the temp starts to rise, fifth at 110 and it rises only slightly above half way where it sits most. I've learnt to drive to the way it likes to tow the camper. I still keep and eye on the gauge, the revs and what gear I'm in.
I've fixed a piece of fly wire behind the grill right across in front of the radiator to catch small stuff that may clog it, insects, seeds grass, but I doubt that would effect it.
Sorry I don't have an answer for you. :(
Became a member of Lcool and ask in the 80's Section. Someone will be able answer your question there. Those guys know them inside & out.

Hope that helps. :)

Factory gauges only provide an 'indication" of what is happening.

If you're worried (and I wouldn't be too worried unless the gauge goes all the way over into the "danger zone"), then I would recommend fitting an aftermarket temperature gauge (eg: TM2 engine watchdog) and I also swear by the Engine Saver product, which tells you if you've lost any coolant.

It always pays to keep your cooling system in tip top condition when you are expecting your rig to work hard on hot days. I would be taking it regularly (ie: at least every 18 months or so) to a radiator specialist and getting them to clean it out (ie: "rod it") and also check replace the thermostat and radiator cap.

thanks all

with you're advice i feel a bit more confidant about how the 80 ran, i also forgot to mention that there was 7 people in the vehicle 2 adults and 5 children aged from 17 to 3 years for the trip home. which took approximately eleven hours mainly due to all the traffic and of coarse the slower speed due to the heat and temperature fluctuations with the 80.

fuel usage was also pretty good i thought, leaving with a full main tank and just refuelling main tank once at Bairnsdale in Vic and only switching to the sub tank about 60kms from home travelling approximately 780 kms in total.

i am due to replace the timing belt so i will get the radiator reconditioned and look at putting in a new thermostat.

thanks again

regards andy

""also the fan ( factory Toyota) stops spinning immediately when engine is switch off so seems to be working as it should"" Although I think most of the other replys are probably spot on, heavy load, hot day, pushing the old girl to 100k, I would still get the coupling on the fan checked. Just caused it stopped spinning when you stopped the old girl, it should have some resistance in it. A little way to check it is when she starts up in the morning the fan should be quit noisy then fade out, better to rev it to about 1500 rpm and you will hear it better, BUT this still doesnt guarantee its locking in properly when required. Some people are under the impression that when cruising along the fan doesnt need to cut in due to airflow. This is incorrect. it will still cut in if required and generally is heard in the vehicle. Another way is next time you can and the temp starts to climb pull over put in neutral pop bonnett and grab the throttle cable from under the bonnet and give a rev the fan should be roaring its head off.
