4JB1 summer temps

Postby magicdeo » Thu Dec 14, 2017 5:44 pm

Hi, does anyone have a digital temp gauge on their diesel isuzu and can tell me the temperature they get up to? We are currently getting some days over 40 degrees C and when driving hard with the air conditioner on i am seeing it get as high as 96 degrees C. The manual says thermostat is fully open at 95. Anyone else's get that high? Cheers

The system is designed with a 13 pound pressure cap so 110 isnt damaging. 96 is fine
I put the factory guage off scale a few times when having fan problems off road. Still didnt boil but a wet finger on the thermostat housing sizzled.
Sanding your knuckles before starting work can help. That way you cant skin them

Thanks Geeves. I have never owned a car with a teperature gauge other than C and H so i really didnt know what sort of temperatures to see
