This is driving me nuts. My wife's 2011 RR Autobiography Black S/C smells like coolant, but there are no visible leaks. This is predominantly on the driver's side that I can smell it. I have been poking around for quite some time looking and have found nothing. Finally after months of this, the low coolant message came on so it's really slow whatever it is.
So far I have tried:
Visual examination of everything. There are some light splatter marks on the driver's side of the engine compartment on hoses and such. Cleaned and reinspect.
Pressure test cap: OK
Pressure test system: Not sure if I am doing this right, but "borrowed" a kit from the local AutoZone, removed the cap on the reservoir, screwed on the correct adapter, connect and pump. System holds at around 7, but not at 15-17. I can watch the gauge go down. No leaks that I can see, no hissing of air, nothing. I can't get under the car fast enough to inspect in real time as it's losing pressure faster than I can get into position.
Water pump 10,000 miles ago by the dealer with OEM part, so I don't suspect that.
Not sure if the truck has a front coolant crossover pipe under the S/C and intake? I cannot find a definite answer on this. I have a 2010 workshop manual and no mention here either of a coolant crossover pipe under there? I'd hate to take it all apart just to find out it does not exist. Maybe someone here will know.
Checked bleeder, and no obvious leaks.
Checked every hose connection that I can see for signs of coolant loss.
I'm about ready to buy my wife a new car, but really don't want to as this one has 80,000 miles and is in great condition other than this. She also likes the rarity of the car so there's that too. Not sure I want to pay dealer a bunch of diagnosis hours.
