One last final check on the old truck currently running the (TD27 88C thermostat) idling away outside tonight with the heater on full tilt and the A/C running with its fan cooling all.

Information Overload:
1st Gear Low Range Test Up/Down Hills
(5kmph @ 2,500rpm each way)
92C up
90C down
Does seem to be running power wise healthy although as before reckon the 82C Aussie manual spec TS might be the perfect happy medium for us down colder south here?

[QUOTE=mudski;789623]If its struggling to reach 76c yeah I agree. Putting a higher rated stat in will just mean the water wont circulate until it reaches it spec'd opening temp. But in TD42 land. Who knows. It may help, it may not.

@mudski Mate! I’m too struggling now to fully comprehend why our OEM & Aftermarket tropical 76.5 TS’s both experienced cold winter big downhill runs of 40C for you and experienced also once as low as 56C for me.
Having found now the OEM 76.5C was the only one out of all three OEM’s bought without a ‘Jiggle Pin’ installed is this possibly the issue?
I did notice how incredibly heaps of coolant pissed out (only gravity pressure) of the empty pin hole when popping the housing off for swapping and makes me wonder how many litres per minute are flowing through our radiators down cold highway fast hills even when the 76.5C thermostat is fully closed?
How much flow does a ‘Jiggle Air Pin’ actually hinder in its hole, maybe 50%?
Is your 76.5C aftermarket possibly missing a ‘JP’ too mate?

Upon closer inspection, I think I can see it, in the centre part of the stat....

Certainly does look like it too thanks mate!
If I was a betting man I’d say that’s our cold winter downhill highway issues for sure!
Just looking at the Jiggle Pin here on the OEM 82C & 88C and its tapered to fit very snug under pressure, may only let a very small amount through to our radiators I’d say.
