Sorry for the snappy title!
I posted recently after I had an Alisport Intercooler fitted to the
1990 110 2.5TD and I was concerned that it was running a lot hotter than usual, this was solo on a cold day. On motorway journeys it would move up to over half way across the white (whereas previously it had only just got into the white - even when towing)Well, last weekend I took the caravan (17', about 1000kg) up to Malvern (from Trowbridge) and whilst it ran a lot hotter than usual, even under the most strenuous conditions (that 1:8 out of Bath on the A46 is a long haul!) the needle never got past the very top of the white area.
So I am now a lot more relaxed. As I was advised, the car is now probably running a better temperature than it was :-)
Cheers
Peter
