Disco TD5 - viscous fan

took mine off last year, & there was only one time I heard the thermostat kick in & that was when we towed our caravan , which is a quite big twin wheel one, to Dorset Steam Fair. Where we park is over the other end of the site up the hill, & when we parked up & idling to shunt the van etc. I could hear it. So I thought 'must put that back on' but hav,nt yet! But I will do before the start of the summer.

To be mate I don't think I needed to put the fan back on for towing, but you know what it's like when you've got something that you really like, you don't want to muck it up !!

Have been running round with it off and all seems stable.

I have noticed a subtle improvement in smoothness, so maybe that's down to not having the fan turning. Incidently I've left the engine cover off, for easier accesibility, without any increase in engine noise.

If the weather permits I'll do the exhaust downpipe de-catt this arvo.

You don't need the compressor running for the electric a/c fans to run in a fail safe mode, that's why they have a sensor screwed into the thermostat housing.

100 clicks (no viscus fan) with that on the back and the temp gauge did'nt flutter once above it's normal mark

if its a td5 then the temp has to be over 106* for the air con fans to kick in

could some one tel me if i take the fan off for every day runing about 50 miles of motor way will it harm my disco 2 tdi

I run both my 200tdi & TD5 every winter without the fans, would'nt risk it in summer though
