Yep mate. With stock 3 way thermostat in Qld they sit on 90 to 95 most of the time and 103 to 105 in low range and higher offroad. Crazy. Cheers
Yeah I'm over here in WA so plenty of coastline to really work the ol girl. I don't really want to end up with a cooked motor in the middle of nowhereQuote:

As said by others the factory temp gauge is a complete waste of space on the dash and an OBD2 unit will give you an accurate reading, Also a low coolant alarm is a great idea for these engines as well.
The 4l V8 also has a well known issue with the head gaskets which is another common cause of overheating and at 270K this could be what is causing your overheating problems and they may need to be replaced.
2012 huh,, I wonder what has changed in a D2 cooling system since then,,
oh right!
Nothing! [bighmmm][tonguewink]
buy a genuine one, take pics before hand, (I doubt an RV8 has lasted this long without someone replacing the hoses, but now would be the time..) use GREEN coolant, test your engine fan, use that OBD2 dongle to check O2 sensors are working, STFT's are moving, and the MAF is in range.
I didn’t think twice about installing a 78C thermostat in my new(second hand) 4.6L after the block split at 178k in my 4.0L.
She cruises at 85-87 and up to 97 when things get a bit more difficult.
I wouldn’t want to see it get any hotter than that.
Want to give me the short & sharp run down on why to change it to green coolant? Something to do with not finding its way out of every nook and cranny like the red OAT stuff? (Spewin as i have new red penrite stuff to go in [emoji1787])Quote:

Believe it mate. Believe it.:bat:Quote:

But later checking of their website shows they changed at some point from the Red (G40) product to the Blue (G30) product.
I dunno what the previous owners had in brothers Td5, but it was green and one can assume that it wasn't OAT coolant .. just something that looked green, and probably the cheaest they could get their hands on.
Anyhow, we flushed it out flushed it again, added the Red stuff I now have (way too much of!) .. and it dutifully began it's process of elimination .. as you said, found it's way to every nook and cranny it could escape from.
Waterpump, fuel cooler, a few hoses ... etc. All fixed and now a few years later, all good.
Hi,
I have the PEM101020 82° hard spring thermostat fitted and it works fine. These are still available from John Craddock according to their website.
Cheers
