Thank you guys for your replies. Good to hear I can block them off, will also be bypassing heater for now, and will unplug monovalve and aux pump after reading sl320's link.

I believe I found the plug for block, listed on this diagram as 35, 53 is what is currently installed.

Is there a part number for the water pump freeze type plug? I'm also replacing the water pump so if there is a specific pump with no output for the cooler I'd love to find one
