Q: How to service and repair the radiator on Mercury Cougar?
A: First service and repair work on the radiator can start by disconnecting the battery ground cable followed by draining the cooling system. The radiator service process begins by disconnecting automatic transaxle upper cooling lines and separating the 2.5L engine expansion tank hose. By removing the fan shroud nut, dismount the fan shroud before securely affixing it next to the work area. After vehicle elevation use a safety stand for support as you must secure any present air conditioning condenser unit. Detach the radiator lower coolant hose before uninstalling the right-hand bracket from the radiator. Vehicles with automatic transaxles require the disconnection of the transaxle lower cooling line as well as the air conditioner condenser detachment if present together with transaxle cooling lines. The procedure ends with removing both the radiator left-hand bracket and taking out the radiator itself. The new radiator installation process requires following the opposite order of removal steps while providing correct fluid amounts to the transaxle of automatic-transaxle vehicles and filling the cooling system of all vehicles.
Q: How to service the radiator on Mercury Grand Marquis?
A: The cooling system of the engine requires draining before beginning radiator maintenance. The cooling fan motor and shroud assembly comes off first followed by removal of pin-type retainers to detach the radiator sight shield. The process of servicing the radiator requires disconnecting upper and lower radiator hoses from this component. The service begins with bolting out the support brackets for the radiator. You must take out the bolts next and position both the A/C condenser core and the transmission oil cooler separately from the radiator to eliminate it. The reuse of hose clamps is not permitted so one should use worm style clamps which replace the constant tension clamps in proper sizes. The installation process concludes by performing a reverse order of removal steps but requiring a process of filling and bleeding the cooling system.
Q: How to service the radiator on a 2.5L engine on Mercury Mariner?
A: Vehicle servicing of the radiator on a 2.5L engine must start with NEUTRAL gear positioning and placement on a hoist. Start the service by removing both cooling fan motor and shroud components. You must detach the upper radiator hose together with both the lower degas bottle-to-radiator hose and lower radiator hose from the radiator. Two A/C condenser-to-radiator bolts need removal before putting the A/C condenser to one side without losing their torque setting which should be at 8 Nm (71 lb-in). You should finish up by removing the radiator then installing the new radiator through the opposite steps of removal.
