Just had a quick look at the coolant level today (car hasn't been driven since yesterday evening) so the engine is stone cold. The coolant level has dropped ever so slightly again with no obvious leaks. I've followed the coolant pipes for pink staining but to no avail.
Could the issue possibly lie with the coolant expansion tank cap? Surely though if the cap was faulty, pink residue would be found on the inside of the cap and possible staining on the expansion tank?
