I'm Thinking To Install the
M7 Thermostat To My R53.
Because They Said Keep You Car Colder.........

That's Correct?

Is At Good Option?

Or Just Keep The OEM Thermostat.

 

Keep the OEM, and if you think its damaged in some way replace it with the factory unit.

If you run a colder Setting Termo it will throw a code.

 

I ran a colder one and had no troubles. I like my motor running cooler. But I ran a 160 degree thermostat. To be honest I think it performed better. If I could get a cooler one for my R56 I would do it on the spot! Good luck!

 

Thanks Guy's!

The M7 Thermostat Is 180°F
So I Think Gonna Be Ok Huh?

Because I'm N' Vegas.
N' Here the Summer is Coming.
Most Of The Time Is 90°F to 110°F

 

I think a 180 degree F. should be just fine. The cooler the better in my book!

 

The MINI will run more efficiently and get rid of crankcase moisture better with the
stock thermostat.

Metal parts in a liquid cooled motor are made to finer tolerances also.... Running it cooler means those parts are a bit "loser" that at a warmed up stock temp....
Unless the car is SERIOUSLY MODDED, I would stay stock.....
The "cooler thermostat trick" is a holdover from the days before computer controlled motors....and much of that stuff does not really apply to a modern engine....

 

I don't think this person has nothing to worry about. Hes only talking 180 degree F. Not to mention his location is more then fine for this. As far as efficient, that word shouldn't even be used in the ownership of a MINI! lol. Even in my location I ran a 160F. Never had a ounce of trouble. Ran that over 100k.

 

Thanks Zippy "S"
For That I Appreciate!

I'm Going To Tried That Thermostat.

Also I Gonna Do The Radiator Flush. ☺

 

I've run the same 180 for a little over 10 years now . It makes a difference during our rather warm So Cal summers .

 

What a lower temp thermostat does is just open earlier. It doesn't really mean that your car will run at a lower operating temp. Just takes a bit longer to get there but peaks basically the same temp as stock 1s.
You want the car to run cooler? Trigger the stage 2 fan by switching A/C on. Should have same effect.

 

Have 199,600+ miles on my MCS and been running the colder 180* thermostat from M7 since it had 80K miles. I have a ScanguageII plugged in to monitor vitals and on occasion when temps drop below 40* outside, I have had to clear the code. Takes 3 seconds....no big deal.

The stock thermostat opens at 193* so 13+* difference shouldn't really make the engine parts run "looser" IMO. What it will do is trick the engine's fuel management systems into thinking the engine hasn't quite warmed up yet thus dumping in more fuel = better engine performance while also helping to keep upper cylinder head temps cooler. The only down side is a reduction of your average MPG. Mine dropped about 2-3 miles per gallon. As with most mods, there are trade off's.


My running temps are always 177* so yes operating temps are reduced.

Would I do it again....Yes. It's a more logical alternative to adding an engine oil cooler to a daily driver which directly alters oil flow rate by significantly reducing the engine's oil running temps potentially resulting in premature engine wear and adding more hardware from which oil can leak from.....

 

Cooling an engine compartment is critical and operates on a balance of both air flow and under hood pressures.

Triggering the AUX fan to draw all that hot air in all the time will only serve to dump it through your intercooler increasing AIT temp, pushing it to your air intake system while drawing power off the electrical system.

IMO both ineffective and counterproductive.

 

I'm on stock t-stat. On the hottest summer days in city traffic w/ 2nd stage fan on, my temps hover from 194F-203F. Yours at 177F is indeed significantly lower. That would surely lower oil temps & in your theory, affect flow rate, too.....much like an oil cooler does.

 

Good to hear it has worked out...remember the early days one winter when you saw a couple codes...
My guess...since there is s stock oil cooker with a coolant loop, the oil temp is high enough to boil off the moisture....
I guess if you can take the 2-3 mpg hit, sounds like an OK mod if know what you are doing!

 

I have one sitting on my shelf I would probably part with as I live in a cold climate and have no use for it.
