hey all

I own a 2000 model 100 series with what looks like an aftermarket
safari turbo set up & the old 1hz donk
I have had it for about 6 months and all was well untill I went to tow a mate home who rolled his ute, travelling on the hume back home the cruiser began to get hot, not quite to the red but close enough while travelling up any sort of hill, once she was on the flat or not under to much load the temp came back down to normal.
I can travel up any of the mountains down toward the coast no worries at all, she just can't handle the extra weight
What I am thinking is that the turbo is plumbed straight into the factory exhaust system, which may be restricting the system?
Any advice welcome folks, I need to pick up a caravan next week and need the big girl reliable.
Coolant and radiator all seem to be in good nick.
God I miss me hilux
cheers
Robert

Thanks fella's
Will try the obvious first and go for the cooling system, all looks clean with no blockages in the fins so I will get the radiator looked at asap, how the bloody hell can I check the fans operation?
I mentioned the exhaust because it really looks restricted if you look at the diameter of the pipe from the turbo to the exhaust
will ring someone in the morning to see if they can go over it
for me
Cheers
Robert

If it has been sitting for a while, you should here the fan roar on start up(even if cold), then drop away, once the temp builts, you should here the fan start to align with the motors RPM, that is to say the more you rev the louder it should get and hang on for awhile.
Another way is to grab the fan(motor OFF) by hand and check for resistance, if fan turns easily(almost freespools) she's gone, If your near a new car dealer pop the bonnet of something similar,do the same test to give a guide to what to look for(resitance).
To fan will of course turn, just not as easily
What have you got in front of radiator? may be contributing factor.

Hey shane

yeah nothing in front other than the air con condenser, have tried the resistance and it feels like a bit is there.
I know what your saying about the sound and I'll pay a bit more attention tomorrow on the way to work.

Harry

Will get a new cap first thing and then let an expert check it out, I hope it's fixed though cause the only way I'll know for sure is when I pick the caravan up next weekend.
Not the best time to discover it's still cactus eh

Cheers Fellas

If you can spare 30 mins, put a piece of cardboard across the radiator( as close as you can) and fast idle 1500-1800 and closly monitor temp and the fan SHOULD kick in once the temp rises (10-15min)and stay with rpm, not fade away quickly
MAKE SURE you keep an eye on the temp,
I have 2 toyotas, my 100 sereis (1HZ) fan is quiet and hard to hear when in vehicle, however my petrol MWB leaves no doubt it's working
