Hi,
Just a quick follow up. I had some high pressure fuel line with me &
did a bypass from the water pump up to the thermostat housing, bypassing
the oil cooler completely. A 20 minute repair once I stepped back and
thought about it. Spent about 2 hours trying for a "proper" fix with
silicone Rescue Tape in a crazy awkward spot, gave up and then had the
idea to do the bypass.
Weather was favorable... rain and 7C in Lake Louise when I started
driving. 90 km/hr with a tail wind! Stopped a few times to let air out
of the front radiator & the pressure tank since I had lost about 2
liters of coolant in the process of my messing around. By the time I
got 200 km, everything looked 100%.
Thanks for the wisdom everyone!
Cheers,
Steve W.
