Has anyone heard of an engine running too cool and not at normal operating temperature?
Anyway, this is the deal.
I assumed that my engine in the EL was not running at normal operating temperature and running too cold thus running too rich and using more fuel. So i replaced the thermostat with a brand new one, new coolant and still running fantastically cool even on warm days. I have even given the engine a hard workout in 1st and 2nd gears at high revs and the damn thing still will not get hot. I gues this is a good thing in a way, but i think it is using more fuel due to its colder operating temp.
Is there anything else which i probably dont know about which would cause this to occur? Not that it is a real problem as such, but i think my economy may be affected due to this.
Any ideas would be great.

Thanks.

For one you don't want it running too cold, a cold running engine wears a lot faster than a hot one.

What temperature stat did you put in? If it's std try going one hotter and see how it goes.

Remember guages and sensors are not always 100% accurate either.

Using a 91deg tstat. Standard factory issue.
Its not running too cold to the point that it doesnt heat up, but i think its not running at the temp it should. Maybe its because i also have a new radiator and i was used to the car running hotter when i had the previous rariator in it.
You could be right. Maybe the temp gauge is probably not telling the truth.

At what point on the gauge does the needle normally sit?

On my EL the needle sat on the 'A' of normal.

You could also put you cluster into diagnostic mode, which will give you the temp of the coolant.

Dash trip thing? Please explain.
Im assuming you can find out the temp of cooling system on the trip display. Is that right?

Yes... And the radiator fixit man has spent millions of $$$ and hours of hot and cold weather testing as well, to state that as fact. :shock:

Ford specify a 91 deg thermostat. I've used them for the past 6 + years in my EL and never had a heating or cooling problem. Every Ford that has come out of the facotry uses that temp thermostat.

The ECU is designed to run the engine at this temperature. Anything below may cause you to loose a few fuel saving features.

The needle sounds about right where its sitting. Look up the doco on dash diagnostics to bring up the diags. This will tell you the engine temp as a number.

The problem may also be your temperature sensor. As they age they become less reactive to temperature changes. They get covered in crap, etc, etc. When I changed mine, not only did I get more power and less pinging, but better fuel economy and a more accurate temperature gauge.

Man that is a crock of s**t.

The only reason why ford run a 92 degree thermostat is to meet emission standards. The computer will still work fine with an 82 degree thermostat. BPT performance shop sell these thermostats and have done enough tests to show it will not affect fuel economy. The ECU will still go in lean cruise mode.

On my car the temp needle sits just below the L. Never had a problem and fuel economy hasn't changed from when it was running a 92 degree thermostat.

Yeah Arm you're full of it, and this is coming from a guy who posted this:

Talk to any engine builder buddy, the thicker oil you use will reduce the cam overlap noise coming from the extractor pipes and thus can change your engine note a little.

you must not be the sharpest "tool" in the shed....lol.lol....lol.........

and yeah i am still right about about ford using a 92 degree thermostat to meet emission laws.

It was used because the combustion chamber needs to get hot enough to burn nitrogen dioxide and thus pass the emission standards.

I agree dude.
I went from 15w40 to 20w50 and my car sounded heaps better.
I unfortunately lost a tenth down the quarter due to less cam overlap.
Worth it for the sound but.
Makes my 4L I6 sound like a 4.25L I7.
Sick as.
