Q: Radiator, cooling system leaks 2006 Nissan Murano

Hello - sounds like the problem is getting worse! Current-day radiators utilize plastic end tanks, assembled on aluminum cores(the shiny fins running across the front of the engine compartment). This assembly inevitably starts to leak over time. I recommend a coolant leak inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs. This will determine if it is only the radiator leaking (which should be replaced), or if another cooling system component is involved.
