Engine bay fan 9 months 2 weeks ago #197021

Long time member, well several years, but first post. Engine bay fan has stopped working on my 02 160.

Tried pulling the sensor nothing, tried new fan, replaced fuse and relay still nothing with sensor unplugged cant think of any other options apart from ECU!

So apart from any bright suggestions on how to solve it, or quick temporary fix, OH is tearing her hair out as we are due to go to the lakes in a fortnight in it, question is with cooler weather and not ragging it any dangers in using it without the fan working?


Cheers

Bill

Hi Bill,
Would not worry about it, my fan has not come on all summer. Yes it does work, came on all the time when I had a dodgy ECU in the past. Many reports that they only really kick in when driven hard on a very hot day . And if my memory serves me right , the parameters for the engine bay fan are higher in a VVC 160 than in a standard 135 anyway so will come on / stay on even less.

Cheers, Mark

About 4 or so months ago I did a detailed post on this.

VVC thresholds are higher. and yes the fan rarely kicks in. Only when the engine is under load (ie up a hill going hard unless you are in places like New Mexico.....) and ambient temp in the engine compartment is high.

The best way of ascertaining whether the fan comes on is using PScan live and logging the data. Makes interesting reading and you realise then that the engine fan is hardly used.
