Thanks for the reminder on this Don. I might just try it after my next
flush. My coolant temps are mainly under control, but my oil still climbs a
bit higher than I'd like. I used to see 275F+ oil temps over mountain
passes, but since installing a V6 TDI oil cooler, I haven't seen above 260F,
even pushing it hard on this last trip. But I can tell the engine is hotter
than it likes as I start to lose power. Coolant temps never went above 3/4
on the gauge.
