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.
