Saab 96 - Fitting an Electric Cooling Fan


As part of the work to cure an over-heating problem, an electric cooling fan was fitted.

In the end the over-heating problem turned out to be the gauge mis-reading, but the electric fan still helped the engine warm up quicker and run more efficiently.

 

 

 

 

 

 

 

 

The fan chosen was of 10" diameter and made by Kenlowe. It was of the 'blower' type so it could be fitted in front of the radiator in addition to the mechanical fan.

The fan came with securing ties, thermostat, adjustable switch and top hose gasket. The optional manual override switch was not ordered.

 

 

 

 

 

 

 

 

The fan was fitted to the radiator core using the supplied ratchet ties. The fan had to be positioned as low as possible within the radiator core to avoid a clash with the bonnet release mechanism.

 

 

 

 

 

 

 

 

The radiator also had to be tilted back at the top to ensure the fan didn't touch the front car in the area shown.

 This was done by making some simple metal brackets to hold the top of the radiator

Top radiator hose connection with thermostat inserted.

The thermostat was fitted to the top radiator hose and the variable adjuster secured to the inner wing of the car.

The kit included a novel gasket to allow the thermostat to fit the hose without leaking.

To adjust the setting for the fan to come on. The engine was warmed up and left to stand in the driveway. Once the temperature needle approached the red, the adjuster was turned down until the fan started.

 

 

 

 

 

 

 

 

Initially the fan was used in addition to the mechanical fan but after several trial runs, it was found that the electric fan provided more than enough cooling on its own.

The mechanical fan was removed along with its pulley and a new shorter fan belt was fitted (975mm).

The shorter belt was from a 1984 Saab 900.
