Do you have to remote the thermostat to flush cooling system in '97?

I've got a 97 XLS (V6) and have drained the radiator and block of its coolant. The Haynes manual says to do a flush but removing the thermostat but does that *really* need to be done?

Thanks!

nope, not really....but it does let the coolant flow faster and earlier.
if you do remove it, go to the dealer and buy one. DO NOT REPLACE IT
WITH ONE THAT IS NOT FACTORY RIGHT FROM THE DEALER! yspert
