hey there. I replaced my housing earlier this summer with a motorcraft one from my local parts store. i thought it was leaking from in between the housing and the head, but found out afterward it was from the sensor plug on the bottom. check that first before you pull it off for nothing. later.
is there any difference in going with the 180F thermostat over the stock temp? i've already replaced my plug o-ring and its still leaking, looks like from the housing now. i'm just not sure which temperature of thermostat i should get on the CFM website
ok cool. what is the actual difference though? i'm planning to get the SCT Xcalibrator 3 tuner in the future. would the 180thermo be a benefit? i'm just curious what the actual difference is from the OEM 197F thermo
yep thats the one. i replaced the o-ring inside mine and the thing and its still leaking. there's fluid all over the place so i can't really tell where its coming from. this "revised thermostat housing" says it comes with everything needed to be changed out. i just bought it tonight and it should be shipping out in the morning.
this is the link for the revised thermostat housing for the SVT focus. the plug that many of us seem to continue having problems with leaking has been completely removed. the hole where it goes has been filled in and sealed. upon looking at this housing just after unboxing it, i would highly recommend it. ive already replaced my o-ring twice so i've got a good feeling this will be $160 well spent. i will be having it installed this weekend along with a coolant drain and flush. ill be sure to let everyone know how it goes.
if anyone can tell me how to upload an image ill upload the pics of the housing just after i opened it from the mail.
just got the new CFM thermostat housing installed. looks like the o-ring between the engine block and the old thermostat was bad, not sure about the o-ring i'd replaced in the plug. i've got pics if anyone can tell me how to upload them to this site.
i'd highly recommend the revised t-stat housing from CFM. i looks like a much better design.
