Loss of coolant, over heating on hills, bubbling in the coolant fill bottle, replaced several radiators
Head gasket leak causes coolant to be depleted after driving 20 to 30 miles. Overheats. Have to stop and replenish coolant. On top of oil leaks and and noisy 4th gear, I'm scrapping it and getting something else.
