Purplexed

Can I assume that this means to turn on the heater to full so that the fluid circulates ?? Will the system bleed off if I turn on the heater ??

I located the heater valve , but no other description or way to "open"

I also noted that the manual does not tell you to flush the system and make sure that the heater is on while flushing . This looks like an omission to me.

Thanks for your response.

My 93 SC400 manual said the same thing. I don't know what the h#$l that mean either; I thought it mean to turn the heater on maximum to bleed the sys.?
