Right, appears to be leaking. So, is this part of the water cooling system? Not sure basically how this works. Diesel turbo. Can anyone explain further if this is a water cooled device please as the top half at front is wet and showing signs of water leakage. Definiately not the radiator nor the air con condenser.

Unless is the Mercedes diesel. Either way, it's in a Patriot.

The charge air cooler (also called an intercooler) is part of the air intake system. It cools the air after passing thru the hot turbocharger. I don't believe the Patriot has a water-cooled unit, so you're likely seeing water from the radiator instead. I'd get under it with a flashlight and see where exactly it's coming from.

Well, it is a new radiator fitted last June 25th 2013. Always seemed to have a problem with pressure, in that there appears very little pressure in the expansion tank. Fluid down intercooler feels like 'gritty' water, no smell.

Temp remains constant, fans working etc. No signs of overheating. There is though a very strong smell of hot rubber after a journey.

Radiator is dry, likewise the air condenser. Along the top of the intercooler is a layer of green mildew. The cooler has a layer about 2 inches or so of wet along it's front from left to right etc. Can also see some drips on the lower air vents in the bumper. Again this is water substance.

I am not losing water from the expansion tank but there is little to no pressure in the tank and can take the cap off straight away after a run.

Dark now and working for local supermarket this weekend driving articulated lorries so will not be able to get a good look at it again until Monday.

I too thought that the Patriot was an air to air cooler but this water has to be coming from somewhere. Also fuel consumption has increased this last few months and still dropping. June had major service etc so all oils and filters changed. Though I have heard recently of diesel filters blocking due to this latest additive fuel companies are using.

Well, the green mould is nothing more than due to the damp conditions we get here in the UK. Wiped off. Checked both days after using the car to get to work and each time bone dry. Also have the same sorft of thing on the window rubbers due to the car being outside most of the time.

All radiators etc are dry, though that persistant smell of over hot rubber still exists. All fans working as well. Mind you if I leave a shirt in the car overnight it is extremely damp in the morning. Likewaise my HVis jackets I use at work.

Plenty of power in the engine and accelerates fine. Just looking at why this increase in fuel consumption is happening. At one time I had a consistant 42mpg, now down to 32mpg.
 
Smell of burning + increased fuel consumption = brake sticking. Feel all your wheels after a run to see if one is hotter.

No it is a 2ltr 07 plate, so no dpf. Owned since new.
i have a dpf on mine(09 2.0 crd).
