Reply With QuoteFrom ambient 22 -34 deg C, with a 50/50 coolant, new radiator and t'stat, the gauge never goes above half way... but the Torque App via OBDII port shows 93-96 degC. I keep an eye on it and remain "alert but not alarmed"

SupporterI'm a little concerned about the temperatures im seeing on the nanocom. It was 32 here yesterday, so not hot, but after a few minutes of idling (no aircon) it was up to 99.
And driving around it varied between 93-97.
I have a feeling the coolant mix may be a bit rich....

Thats normal operating temp.
Mine runs at 95c.
Even on ambient 40c day I dont recal seeing over 98c with a lazer temperature probe.
I did have a wayward temperature gauge a few weeks ago and thought things were going horribly wrong. The gauge always sits right in the middle.
Investigation revealed a little corrosion on the plug for the temp probe, with a bit of a clean up all is normal again.
A fast warm up is good.
The cooling system on the P38 is excellent.

SupporterGlad to know im within the bounds of normality :what:
I would have though 95 at idle....anyway.
I suppose it's just not 'proven' yet.
We had a 52 degree day a few years ago and the temp guage didnt go above half that day.
On a seperate note my uncle in his new d3 towed dad's 88 rangie from Traralgon to Geelong on that day with the cruise control on 100 and still got 13 l/100km, and the temp guage didn't get above 1/2.
I'll wait to a 40d day and take a slow drive around town.

SupporterI had a feeling there was something wrong.
The viscous fan want working. And there was a large (50cent sized) O ring sitting underneath the thermostate plate blocking around half the water flow.
Now with the aircon on flat chat, running around town today (38c) it sits on 95-96. After a few minutes idleing it went up to 100 - but I think that's as good as it's going to get. Driving on a flat 60kph section it'll drop down to 91.

Mine runs around 92 and never seems to move much I have never seen it at 100 just driving around

SupporterWent for a drive today (40) again. At 100 it sat on 87, and up to 93 moving around the yard. But the fan didn't seem to turn off, even at 87... not sure.

Viscous fan or thermo? The thermo should only run with the A/C on!

My new HC engine varies between 89 and 91. Rock solid with new water pump and hoses and the bypassed throttle body heater. Will have to consider additional alarms to ensure the system stays safe.
But Jeese does it get hot under the bonnet. Can't be good for the plastics. Any thoughts on a bonnet scoop leaving aside the aesthetics, which comes down to personal taste.
