Q–I recently had the A/C condenser replaced on my ’92 Ford Escort due to a small pinhole leak. The mechanic said it may have been caused by an object–like stones–hitting the condenser. I also had a water pump and oil pump replaced. Is it possible to fix the hole on the condenser by welding or covering it with tape? Can I solder it or patch it for under $5? Can other parts, such as oil pumps and water pumps, be patched .E., Elmhurst
A–Small leaks may be patched, and we have done so with epoxy compounds. Years ago we patched a hole in the aluminum side case of a motorcycle with epoxy, and it held for as long as we owned the bike. Other small leaks, where there isn’t too much pressure, can be patched this way. A few that come to mind are oil pans, windshield washer jugs, coolant reservoir bottles, exhaust pipes and so on. We would not try to patch critical parts–especially those in the engine such as an oil pump.
Q–I am in the market for a used certified car. I am looking for imports only. But I have a feeling that the certified cars are not usually like they are advertised. I have heard that some dealers roll back the odometer on used certified cars to bring up the price. Is that true .P., Hanover Park
A–We will not say there is no such thing as odometer tampering, but if a certified dealer is caught doing it, he risks losing his certification and may be prosecuted.
