I am going to replace the one module for the fan,... it got stuck again and stayed on all night without us knowing and drained out battery.. Volvo fan won't turn official. it didn't come on right away when we turned off car, sometime in the night, so I think it is best to replace it... what is the other switch I should change to make sure it doesn't happen again. If you feel that some of this is beyond your scope of repair capability, don't bother with it. You do not want an all metal radiator in your 960/90 series car. My ECU lid was missing the left right screw and it seems as though a lazy mechanic had just broken it off at the back right one due to the need to pull the wipers off to access that screw.
Do not use heater hose stock instead of the OEM hoses. It turned out to be an ideal device for the slotted hex head worm screw on the hose clamps. Off came the fan and shroud. The problem turned out to be a leaking radiator ATF cooler. Gradually deepen the cut. Tips: - don't overtorque the hose clamps on plastic radiator connections or the coolant line nuts. To drain the system afterward, remove the block drain and the pump end of the lower radiator hose, bending it down to drain the water. Volvo fan won't turn off heat. Hence, periodically test the installation to make sure that the bulb, the sensor, and the circuit operate correctly by performing test v) above.
It has a small amount of silicates to improve corrosion protection for lead and aluminum, but not so much as to precipitate out, and in addition uses an OAT package. The other wire goes to the fan. 3 volts) can cause damage to metal surfaces (especially aluminum). The Cooling Fan Relay is tested for operation by running the engine or turning on the A/C. Volvo fan won't turn off air. The oil drip ends up right on top of water pump seal causing it to fail. Use a backup wrench when tightening coolant line nuts.
Conversely, the cooling fan may not run at all causing the engine to overheat. The water pump can still churn suds out of the remainder. Don't go by part numbers you see in pictures, as they vary by manufacturer. If the air is only warm, there likely is an air bubble in the heater core. If you have a small hand, you will be able to grip the hose under the exhaust manifold.

My nine-year-old 945T developed a very small crack in the top of the reservoir... it bubbled a bit when the engine was hot. Disconnect and remove temperature sensor if installed. Over time, these will cause corrosion and material breakdown in radiators, heater cores, hoses, and engine components. The fan motor relay performs the action of a switch, sending 12-volt power to the cooling fan and initiating its operation. The gasket itself provides a great seal without adhesive but adhering it to the pump first assures that it won't slip when you're installing it. People just had no idea.
Put a nut on the stud so that enough of the stud is sticking through the nut to place another nut on top of it. It uses no sealants and relies on a friction fit.
