Heating the regulator in a D2

[Pedro_The_Swift]

How hot does the coolant need to be?
The system is set to swap fuels at 35c.
but driving down the road should the hoses be too hot to touch or not?

As per my reply to your other thread (why the two threads?) your coolant seems to not be circulating enough. The hoses and converter should be essentially at engine temp, around 90C, too hot to touch.

Yep. Mine are too hot to touch.
