hey there everyone,i was just driving driving down the M1 and i noticed the temperture creep up just over half way it normally sits just under half way,i was sitting on 110kph when it went up then when i pulled off the highway back down to 60kph it went back to normal.
when i got it
home i lifted the bonnet and had a look everything
looked fine the radiator is full with green coolant,overflow bottle was at right level there doesn't seem to be any leaks any where that i could see,and i checked the viscos hub on the fan and that seems ok,i couldn't stop it while it was idling..only thing i can't
check is the thermostat.
so does anybody have any ideas or has had the same problem or know what it could be,or is it possible the gauge could have had a hissy fit.
oh yeah the car is a 98 LC 105 GXL turbo diesel auto 228000km
any help would be great
cheers

Hey B,
i would be replacing the thermostat and getting the radiator flushed,
check and be sure the viscous fan is working correctly,i am not sure if the LC105 can be cleaned out and refilled(the earlier hilux could be) reminds me i must
check mine to see if it can be done.but it will be one of the first three things.cheers Paul

At 110km/h the fan does nothing to aid cooling. Get the radiator flushed and
check the thermostat.

brentos,
My 99 did the same thing and it was the silicone in the fan hub, it was only 12 months old at the time but had done 100 tousand k's already.
Start with the cheapest thing and work your way up. Cheapest thing is to drop into a competent workshop and ask them to
check the fan hub, you may be able to just get a few tubes of silicone (available from Toyota) squeezed in there and problem solved??? then if that don't work do the thermostat then ect ect through the cooling system until you find the problem as it could be many things.
Cheers, Trevor.

brentos,
"hey there everyone,i was just driving driving down the M1 "
I assume you mean the M1 on the
Gold Coast? If so, drop into SE QLD 4X4 at Carrara and speak with Sean, he will be able to pin point the problem.
The other thing to
check is the radiator fins, if you do a lot of off roading, the radiator fins can fill with dust, dirt, mud and grass and block air flow through the radiator. This limits the cooling effect on your coolant.
Cheers

Your radiator requires removing and an internal clean.
The viscous fan hub only works up to about 60 km/h. Once you go faster than this the air forced through the radiator is greater. If it was getting hot around town and then cools down on the freeway, it would be your fan hub.
Either that or your fuel pump is screwed up too much. Being a 98 105 series it would be an after market turbo. I suggest you fit an EGT guage and monitor your exhaust gas temperatures as these 1HZ engines will crack pistons and heads like road maps if they have too much fuel.
