Thread: towing tdi auto temperatures and coolers

I have a Madman unit that monitors the auto trams temp, from the pan and after the cooler because I wanted to see the effectiveness of the cooler. (typically 10-15 degrees difference).

The oil is apparently good up to about 180 degrees. I has only ever reached about 130 driving in sand loaded and pulling 1.3 tonnes, yeah I had it in high range with selector in D. Did not take me long to work out this was not a good idea and changed down. Brought home the importance of selecting the right gear as the temperature dropped to around 80 degrees at a slightly lower speed once I had dropped gears.

I do not know if mine being an earlier model locks up in all gears although I have never tried it.

Anyone confirm this one way or another?

Apologies for the long post.

Mike, my D2a definitely locks up in all 4 gears.

Regards. Gordo

Thru a bizarre twist ive ended up with two coolers back to back and a temp guage on the hot side.

Test run went ok, got it to 110degrees after half an hour up a major mountain. Interestingly the light went on at 100degrees! Dodgy sensor.

With the temp guage ill know when to stop for a cuppa. Cheers
