I have my 2006 Volvo s60 2.5t AWD serviced at the dealership per the recommended schedule in the Owner's Manual. Recently between the 37,500 and 45,000 mile service I noticed my "Coolant Level Low" light coming on about every 2 months but I park my car in a garage and have never seen any fluid leaking. I add the 50/50 coolant to the full level only to have to add it again in a few weeks. Today at my 45,000 service the Dealership tells me my radiator is cracked, is not repairable and needs to be replaced completely to the tune of $850. Apparently the coolant was leaking out by my exaust and burns off before it hits the ground which is why I never saw a puddle. They say because the radiator is made up of aluminum and plastic, the leak can't be welded because it will melt the plastic and this is a common problem with Volvo radiators. Just want to warn other Volvo owners.
Got the COOLANT LOW PULL OVER message. Immediately popped the hood to see coolant spewing out from a hose that runs next to the block and into the bottom of the radiator. I waited until the pressure from spewing died down so I can try and feel where the leak is but there seem to be some other cords and/or smaller hoses in the way of seeing.
Odometer 44,500 km. 3 short trips ago warning message "Do not start engine - coolant low". Put in 1 litre of water and scheduled premature major 48,000 km service and tire change. Volvo Service called and advised radiator cracked and requires replacement, and there are some oil leaks. No sign of leaks in my parking stall. Estimates cost: Radiator C$1,000, oil leak parts C$200, labour approx C$600.
