Toyota 80 series temperature gauge

Mate,
best thing you can do if you are worried about temp is to put in and aftermarket gauge with an alarm like a murphy gauge + put in a low water alarm.

RA.

you will know when its getting warm the air con will cut out

The in dash gauge I can't help you with Ian but mine is like yours it boiled a couple of times in Tassie and the guage was only reading half way up.

I installed a "watch dog"gauge and mounted it on the lower part of the dash under the ash tray that way the led lights don't bother me at night. It looked an easier way to do this than pull the dash out to fix the old gauge.

ive been using engine watchdog alarms for a few years now.
they look pretty ordinary - but make plenty of noise when the car is getting hot.

cheap piece of mind.

G'day Ian,
Either install something like an Engine Saver low coolant alarm, which also has a temp sender, I've installed one, it's a good bit of kit. Or you can install a EGT, if yours is a turbo diesel. This is on my list of bits to get.

Sorry can't help you with the mod for the gauge.

Hi Ian,

Maybe try lcool forum, free to join and a heap of tech info. I think you are right there is a mod to get a better reading.
Having said that I would second what Rockape has posted, fit a good quality after market gauge and level alarm and give the original the flick.

Cheers
