Thread: What is an acceptable coolant temp for a Defender 300tdi?

I've never had cooling issue's with my Tdi until a few days ago,I run a Ford XE fan and the front seal let go and it spat all the fluid out so the fan just free wheeled.It's been doing alot of towing in high 40 degree heat as I've moved south of Perth and I've not had to nurse it at all until the viscous failed.

do you have any spring lift?

do you have any bullbar or accessories?

Took all the crap off the front of both my defenders when I was living in the Pilbara and I'm very anal about correctly servicing the cooling system in my vehicles.I think the Ford fan helps the Tdi. Pat

Serge, I picked up an alloy core radiator through British off road. I did have the option to get a oem copper.core, but preferred aluminium.

I am just sitting at coolangatta airport waiting collect my boys. The run from Brisbane was very hot outside with 36 degrees ambient temps. Sat on 110km/ hour and coolant temp read 91-92 and did not fluctuate even up hills. Very happy!

Serge,I thinking along the lines of Dougal and think your fan could be an issue.Have you gotten it up to temp and jammed a paint brush into it to see if it stops?.If you have to nurse it on the flat to stay under 100 somethings a miss. Pat

Unscrew your capilliary temperature sender and put it in a pot of water and bring to the boil[portable gas stove], i did this with my vdo capilliary sender and in boiling water the gage only read 94, now removed and replaced with a auber instruments digital gage[tested against my flir thermal imaging camera to be accurate] that also controls my twin thermo fans[vt commodore] to cut in at 100 and cut out at 96
