35d worsening gas mileage - solved- thermostat/fan/EGR cooler - DIY with pics

The skinned knuckles were well worth not paying someone else a few hours labor.

But I'm a cheapskate. Probably driving the wrong marque, but I'm also a glutton for punishment.

What kind of Acetone did you use? and did you soak the EGR in it? Thank you.

That's like asking 'what kind of oxygen do you breathe' ...

Funny response, I'm not laughing. Forums are to help each other.
Acetone comes in many many forms. From the stuff you get at the drugstore to the stuff you get at the hardware.
This is not my first rodeo, nor am I stupid. A simple answer takes as long to write as an intelligent one.

***UPDATE***
I had my thermostat replaced by an Indy. I am now running at the prescribed 88 degrees Celsius. I do notice the X runs smoother. Should have had this done probably a few years ago. I still get the DPF warning, but I think it is the 250k warning mentioned on this forum in another post.

Just replaced my T-Stat at 110K miles. It probably needed changing sooner. The DIY instructions were a major help. Ended up taking the radiator out to help with EGR flange bolt reinstall. I also tied a piece sewing thread around the flange bolts, so when I dropped them, they could be easily retrieved (use to do this in the Air Force. Dropping a screw/bolt down a vertical stab would cause two days of maintenance).

Damn that’s a brilliant idea about the thread! Wish I had known that sooner! It is possible to get at with the fan and radiator in place.. couldn’t get the fan out without breaking the plugs and clips so I left it in.

Hello all.
Did the thermostats, and while finishing, I can´t seem to get the alarm for too low coolant level to go away.
The system was filled, I have run the electric pump for almost half an hour, I have squeezed all accessible hoses, it has idled up to temperature and the reservoir is full. But the alarm is still there.
I have checked with a scan tool to see if it was a code that had to be reset to go away, but there are no active fault codes.
Where is this sensor for coolant level positioned (radiator, coolant reservoir or ..)?
Could i have forgotten to connect something?

Anyone else encounter this?

Any help appreciated.

UPDATE: the next day the warning was gone. All good, but not sure why it took so long.

well that is pretty ingenious
