[urq] [s-cars] Coolant

With steam coming from the driver side and 20 years on the car, I would
suspect the radiator. If you can't find any residue (some coolant leave
obvious residue, some don't) there is an untraviolet sensitive additive you
can add to the coolant. Drive with it for a while (until you see steam
coming out) then track the leak with an ultraviolet light. BTW the same
additive can be used for oil and gaz leak too. I used it to track a coolant
leak after I converted to Ford coolant (much cheaper, much easier to find
and compatible with the pink unobtainium Audi but leaves almost no residue)
and it took 5 min. to find the leak.
