So my washer fluid reservoir filled up with coolant this weekend, and I can't find a washer fluid heating coil in-stock locally. I was planning to remove the heating coil entirely and connect the inlet and outlet coolant hoses together. I use the -20*F washer fluid and live in the South, so I might stick with this shadetree solution indefinitely. Any danger or risk in doing so?

Only reason I ask is because of the thermostat/thermovalve attached to the heating coil. I don't want to disrupt the flow of coolant to the engine by connecting the hoses together. Coolant flow and washer fluid temp is tightly regulated between 20-30*C in the factory setup.

Thanks as always.
