Hi all. I drive a 2.0l Outlander diesel and absolutely love it. It’s done 125000 miles but has recently shown signs of a blown head gasket, oh the pain. It’s loosing coolant but has no sludge in the oil or water. It does however stink of fumes from the radiator and has failed the blue liquid test. It’s also not producing heat into the car but is getting up to temperature and NOT overheating. Any advice greatly received especially on cost of garage repair for head gasket repair. Thanks guys.
