Had a cooling issue towing and have now upgraded to a ARE alloy twin core rad.
I'm looking at the thermostat now.
daily, with towing duties big van.
Iv'e been a little unlucky in the past prior to upgrade imo with temps getting to 105 C in cool weather on a long-ish approx 1k but low grade climbs, and want to stop this sort of problem before the hot weather turns up.
I've read n read and it seems common for 100+ deg c to be seen as ok, but this is around boiling point and not ok imo.
so little perplexed on which thermostat to use.
Thermostats listed for said car.
Std is set at ----76.5 deg.
aftermarket-----80.0 deg.
a/m hiflow also-80.0 deg.
things floating around inside the little mussel.
Should I be fitting say hi flow 76 deg c ?
Is hiflow a good thing as it will allow more flow partially open, and then open more when pushed to keep things under control when hills appear?
Or just stick with a std oem unit ?
oh and egt's are good, large t/m so that's not the issue or part the problem.
Note- hi flow is recommended for towing according to it's packaging.

Update as the aftermarket temps were quoted wrong they should be 70deg c
