scavenger fan

[oldmanpete]

what is it where is it what does it do?

what is it

Its a FAN for moving air around!

where is it

Directly in front of the engine, pointing upwards slightly, you can see it when the seats are up look down the front,its in a cage.

what does it do?

Keeps the engine housing cool when your stationery and the air isn't flowing over the engine, otherwise the seats and centre console would get rather hot.

[mitchelln]

Also prone to failure due to it's position, right in the firing line for spray and muck. Pretty sure mines dud!

Is it supposed to come on with the engine off to cool things down after switch off?

[Bob]

It won't run if the key is turned off.

On a hot day I switch off then turn key back on for a few mins. Weather it actualy helps...

[g8dhe]

It will only come on when the temperature inside the housing exceeds 80-90c it will continue to run without the key in until its cooled down. Haven't heard of many failures at all more people expecting it to come on every few minutes, its quite rare to come on in my V6.

Is there anyway of testing the scavenger fan sensor to make sure it is working properly?

Yes i think you can test it using e.g. a hairdryer (the sensor is near the handbrake i think) but why bother when an engine temp block gauge and over-ride will produce a happier and more reliable state of affairs

Cheers but how do I know that it is kicking in and switching off at the correct setting?

You'd need a thermometer and a value for when it should kick in? But i suspect that if a hairdryer activates it at all then its working properly.

The values are ..

20c 2.0~2.9

80c 0.27~0.37

You need a container for water ,multi meter,heat source for the water , thermometer and some black cats Whiskers.

.....and it'd be simpler and more useful to fit a tm2 and over-ride switch? Just saying
