**ganador** · 13-02-2007, 02:51 PM

Just wondering what the water temp should be for the 18rg. My hilux had a 18rc now its got the 18rg and needle sits higher on the rg to the rc.

Hi,

Mine sits at 78-80 degrees C. When it's a stinking hot day, traffic and the air-con going it can get up to 82 deg C.

mine floats from 77 up to 90*C.
I have a thermofan on mine which is set to switch on at 90*C and off at 86*C, as opposed to the stock clutch fan setup which tends to keep temps down constantly in traffic.

On highway, mine sits at 78-82 constantly.

if anything mine takes what i would consider an excessive time to warm up, (over 10 minutes usually), it hovers around the 80 degree mark once there however give or take 2 degrees, just like above

when it did run high, i redid my head gasket and it fixed it.
are you just using straight distilled/demineralised water in the coolant system until you are sure or does it have the glycol(coolant) stuff in there also?

i only just finished installing the motor in the hilux so for now im just using straight tap water. the heads been completly rebuild and rings bearing ect, replaced. I guess ill have to get an aftermarket water temp gauge.

not that cheap shit thats 65g/L. put something with a nice high concentration so your head doesnt corrode.

yeah matey, if you just want to put water in it to test, grab some demineralised water from woolworths/safeway at the very least.
It only costs 2 or 3 dollars for 4 litres (you need 2), and it is better than tap water, especially after you have spent all that money on reconditioning a head. you also don't care as much when you find something wrong and have to drain it out (yeah been down that path a few times

).
with demineralised water only, i was still getting around the 82 degree mark when i built mine.
