I've noticed that my 1993 Eurovan has been idling high (about 1500+ RPMs).
And I'm 99% sure that my radiator fans have not been turning on.
?
I'm wondering if a temp sensor or something else could be to blame... and how I might be able to check it.
I did have a leak and a day when it ran quite hot for a 20 minute drive.? Maybe the coolant temp sensor got damaged?
Does anybody have a measuring blocks legend (I have VCDS) with appropriate value ranges for the temp sensor(s)?
I ran an autoscan VCDS, but the 1993 scan results are very basic. No errors.
?
Maybe a vacuum leak as well?
