Thread: What oil pressure and Coolant temp?

ok... found oil pressure...

OIL PRESSURE: 45-65 LBS at driving speeds with engine at normal operating temperature

and coolant temp.. i have a 74 Deg C thermostat... so around 80 Deg C for normal temp????

But what is critical temp?

Can't help with the temperature but the thermostat only controls the temperature at which the system is fully open. This allows the engine to get to a reasonable running temperature more quickly.
The cooling system is pressurised so can be run over 100C (boiling point is raised when the pressure is increased).

Bringing our 2.25 petrol LWB SIII back from WA on a 40 degree C day with the accelerator floored most of the way (head wind), we saw 210 degrees F (99 Celsius) on our gauge continuously with no problems eventuating. If it went any higher than that we would slow down a little until it came back to 210F or less (precautionary principle), and at planned stops we slowed a little before stopping and switching off.
It never overheated.
Hope that helps,

PS: We have since reverted to the standard LR gauge as the after-market gauge it had been fitted with couldn't withstand the vibration from the Oodnadatta track.
