Removing any fluid residue after a leak repair is part of a thorough job and not an afterthought to it.
Sometimes lingering liquid residue such as oil or coolant causes a vexing comeback by creating the false impression of a persistent leak. Of course, a vehicle owner interprets a persistent or ongoing leak as a failed repair.
Remember that all leaks are not the same. Depending upon the type of leak and its location on the vehicle, liquid residue may linger even though the leak repair was successful.
Worse yet, lingering liquid may slowly drip from the vehicle for a period of time until there's no residue remaining.
Mind you, a motorist may never notice any remnants of the old leak because he or she doesn't look for it. And the leak location simply may be difficult to see, for instance, without raising the vehicle on a lift.
Another factor is the condition of the customer's garage floor or parking spot. Over the years, a motorist may have tolerated various leaks until he could no longer ignore them — then the vehicle went in for repairs.
Consequently, the garage floor or parking spot already is so oily that the car owner usually won't recognize additional drips.
Matter of fact, this customer may have become so accustomed to the accumulated oil on the garage floor that he takes the mess for granted.
On the other hand, there are conscientious car owners who keep a garage floor clean in order to spot leaks quickly. So, this caliber of motorist may recognize the slightest leak after the liquid hits the garage floor.
Clearly, certain areas of automotive repair require technicians to make accurate judgment calls — including any clean-up following a leak repair. After all, today's leak fix may not be anything like yesterday's. Some leak repairs simply demand extra attention when the job is done.
