Does 82 degrees at the thermostat housing measured with a laser thermometer sound about right?
Thanks,
Dave

yep, well depends on engine but 82* isn't far off
thermostats meant to open at 83 or something around there IIRC

Thanks, I just don't want to cook anything. Both the oil temp and the water temp gauges are more than 1/2 way across which started me wondering. It was 30* out today in Arizona.

You could fit an earlier opening stat, or more cooling through extra fans or a better radiator

Have you got all of the fabric ducting and everything in place on your ttruck? Mine was missing all of that and had been monkeyed up with a fan from a VW - i dumped all of that and fitted it up with a Kenlowe puller fan on the back of the radiator.
If this interests you, go have a look at:
Richer Engineering
There's a write-up with pictures.
To answer your question, not completely sure I'd trust an external reading there with a non-contact thermometer. I've seen them read inaccurately unless right on top of the item in question - the spread of the focus area on those things is not all that easy to tell.

Viscous is better than a leccy, look at kenlowes site they say in hot weather keep the viscous and fit the kenlowes as extra

If I'd actually had the fan on the 2.5 I might have agreed - but that was not an option I had open. The 2.5 didn't all have a viscous clutch fan - mine (ex-MOD) had a fixed fan in any case....all of which was missing anyway.
Have to say I'm of two minds on the statement, though - a nice big electric is going to pull well with no isues of engine RPM - if you sit in traffic as I do in Summer (commuting into and out of Boston) an engine-driven fan is nearly useless.
If airflow is an issue one thing I'd be looking at is to make sure all that ducting is still there and intact - a blown out bit in the cloth connection between the engine and radiator shroud could blow the whole thing to hell (if you'll pardon the pun).

I was sorting the heater out and changed the stat last week.
I was offered a 74 or 82 degree stats.
74 allows the water to follow sooner round the system and helps with cooler running.
I put the 82 in cause it does mainly short trips 10mile or less.

You'd be looking at 8-900rpm at idle for a viscous though, bigger blades with
more mass flowing. Blades are huge compared to electric hence needing twin fans if removing the V8 viscous

All the ducting is present and in good shape. I'll probably put a cooler thermostat in and see if it makes a difference. Thanks all!

Mine sits a fraction below that and never budges regardless of what I do or don't do. I thought it was meant to sit around there?

Another warm day and I noticed that it runs hotter when I am on the highway (60+ MPH) than on the streets (45 MPH).
Any thoughts before I swap out the thermostat for a cooler one?

I think you're doing a completely unnecessary job. Clearly, the faster you drive, the hotter the engine gets as its working harder, faster and generating more friction...

60+ in a n old 2.5n/a is thrashing it.

That's why I ask, thanks. Slower is better anyways.

I would advise you to install an oilcooler with thermostat, especially when the engine has to operate on heavy circumstances like towing, hot temperatures (> 25 Celsius), slow city traffic or long stationary duties.
