My cars an
Ibiza, but would like to hear what you Leon guys think of this;
(mines a 1.8T by the way)
Since I purchased my car (about 2 years ago) - in the cooler months if I turned up the cabin temperature or went on the motorway, the dash temperature would drop from 90C.
If I hit traffic, it would rise back to 90C.
I knew it would be the thermostat opening too early, but put off the job for over a year - as it was fine in the summer months.
Anyway, I fitted a new thermostat (opens at 87C) about a month ago.
The temperature gauge reaches 90 a lot quicker, and stays there.
One thing I have noticed when I have finished driving is that the rad fans are going, this happens about 4 out of every 10 drives.
I always drive slowly about 3/4 miles before I finish driving so to not spool up the turbo.
I'm thinking this is probably normal & im being abit over cautious, but im half tempted to fit another thermostat.
