  Q: How should you perform the work with the radiator on Volvo 940?

  A:

  Perform this work only on a cold engine. Start out by disconnecting the negative battery cable and setting the heater control to MAX heat. Remove the expansion tank cap and place an appropriate drain pan. Open the cock at the right-hand side of the engine block and fit a hose to collect the coolant, open the radiator draincock. Close the drain cocks in the coolant solution or coolant unit once the coolant is drained completely. Proceed to take out the cooling fan and the cooling fan shroud, and disconnect the upper and lower radiator hoses. For those with automatic transmissions, disconnect transmission oil cooler lines at the radiator and plug the lines immediately, catching the spillage in a separate pan. If equipped, remove the connector on the temp sensor on the driver's side top of the radiator. Remove the radiator retaining bolts and brackets, and then remove the radiator assembly from the vehicle (please note: on models 850/C70/S70/V70, the radiator is removed from the bottom of the vehicle). To install the radiator, place it in position and install the retaining bolts. For automatic transmission cars, attach the oil cooler lines, and then install the fan and shroud, and the lower and upper radiator hoses. Connect the expansion tank hose, and make sure the overflow hose is clear of the fan and without sharp bends. Fill the cooling system, via the expansion tank, with 50 percent antifreeze, 50 percent water solution and reconnect the negative battery cable. Operate the engine to normal operating temperature, bleed the cooling system and check for leaks. Top up the cooling system as needed, replace cap and check and top up automatic transmission fluid level.
