What problems will it lead to when you had a 180 deg thermostat in your Focus and a tune ?

Lots of racing around for longer periods.. plenty of full speed freeway driving. HOT Summers..Warm Winters..

No problem. Do it. I am certain you will be happy.
No way would I change the thermostat unless I was racing the car.
For daily driving? ONly if you live in the Middle East. Or maybe Australia/Africa with typical temps over 100F.


For wannabe racers this is a great mod. You can talk about it. impress your buddies. But unless you are actually racing.. It is not much use, and generally a bad idea. If I have to explain it from scratch? Hah.
Good luck though.

Sounds like you have no idea why you are saying all this I have been researching this for hours over last few days and it really does not have negatives. Unless you can give an explenation nobody should listen to you

Of course no one should listen to me. I agree fully. Forget i even posted it. Be happy.
Sorry i even mentioned it. I am sure it will be perfect.

Oops I Googled lower temp themostat and the very first post I cut and past for your pleasure:
""
We have discussed this on another board, but once the car is up to operating temperature, there is NO DIFFERENCE between having a low temp thermostat and a high temp one, once they are both open. It is radiators, not thermostats, that are responsible for coolant temperatures. The only difference is that the low temp opens sooner, which actually causes your engine to take longer to get up to operating temp, which is not necessarily a good thing.

So, it's really only the "interim" period that is different, when your coolant is between 160 and 190 degrees, and I have not seen any definitive issues that occur during that timeframe.

Still curious what bad things happen to your Focus with the 180 deg thermostat installed , you talk about it like you must have a lot of experience with a 180 thermostat in a Focus engine ????? If you havent done it just say you have no experience and it all opinion ??

Yes please explain it to me ? I have only installed about 70 of them personal in Focus engine and tuned them and tuned another few Hundred Foci with 180 deg thermostat with no issues

It seems there is a lot of people that have opinions about the 180 deg thermostat but they all dont seem to have ever tested them to back up there opinions or questionings

Good luck.
Guy obviously didnt know what he was talking about , its the Fans / Raidiator that are responsible for coolant temperatures. Fans being the key , Thermostat has very little to do with the engines temperature except for cold days , Thermostat is there mostly to bring the engine up to its operating temps quicker , On the Focus depending on ECU code, year and engine thats 145 to 165 deg in the ECU settings , NOT the 180 or 196 that the thermostat is

The tuning WITH the 180 deg thermostat is the key as well , this changes the " Up to temperature " settings , low / high speed fan settings and a few more things

No,i agree you are 100% right. Obviously the manufacturers are tricking us all into using thermostats 20F too warm so we ruin our engines faster and thus have to buy new cars sooner.
I wonder what is in thier collective heads to do something so evil and stupid.
And that it is not a big scandal?

"Car makers want YOU to over-heat Hah ha" as the headlines..

It HAS to be a conspiracy.
I hope you can bring the Truth to all Humans.

Where are you getting the idea that Tom is trying to say the dealer puts bad tstats in the focus? He never said the stock tstat is bad for your car. Nor did he say you NEED to perform this mod to run safely. Obviously you don't because there plenty of people who run his and injected's tune with out the 180 tstat. I see people all the time attack him on the forum like he doesn't have a clue what he is saying. I can tell you right now that anyone can look up something on Google and copy and paste it. I'm sorry but there is something to be said for experience and time on the job.
