Ok guys,
As we are on this subject, I have some questions too as I am working on a Zetec4 also in a Merc that is soon coming south to Las Cruces, NM for a new home in HOT country too.This car has a special 2 valve thermostat. As it opens it shuts off something else in the back of the thermostat housing. This thermostat design is not an after market type and so far, I have only been able to find a replacement at the Ford dealer for $12 and they sell only 192 degree ones here. Are you all using aftermarket 180s? I am NOT impressed with working on this engine as most everything seems to be designed with you going back to the dealer for service or his parts...Even with the new thermostat, this Zetec4 is running warmer than I want it to....We all need to find some good answers to these cooling questions that we all are experiencing....PS. Been to Yuma in JANUARY several years back with my Beretta....Had to turn on A/C that day ..TOO HOT for me...Duane Koss / Blue Springs, MO
