I've run multiple VW turbo-diesel engines in Vanagons (including 1.6TD, 1.9AAZ, 1Z, AHU, and ALH) without any aux coolant pump/sensor and have never had any coolant issues as a result. As far as why VW added it to the JX, you would need to ask VW. While you're at it, find out why they added the BOV to the intake manifold... |

I don't like engine bay clutter and so did not implement it in my ALH.
Letting a diesel idle a minute or two after a hard run is just good diesel hygiene anyways.
I added an override switch to the radiator fan instead. A minute of idle with fan on low drops coolant temps by a lot.
All engines from AAZ on don't get that hot in vans anyways...
The 1,6td on the other hand... |

In 2014, from Rockford, Illinois, enroute to Alaska, pulling a popup camper, the cooling system in my 84 tin-top with an ALH lost pressure. The hard pipe come loose from the back of the gauge at the dash. Yeah, I do have such a gauge.
So, rather than try to make a repair, I drove on watching the temp gauges to make sure the engine didn't over-heat. After 100s of miles at highway speeds and running the AC, I come to the conclusion everything was going to be just fine.
We completed the entire trip with no issues.
I agree in some circumstances, the engine should be allowed to idle for a couple of minutes so that the Turbo cools down. The temp drop is rather fast based on what I've observed on the EGT gauge. _________________ '84 Vanagon Tin-top, ALH TDI. 1989 Tin-top
